1.2.2 (October 22, 2013)
# general
- new 'worker' setting for outputs. This helps improve throughput on
request-oriented outputs such as redis, rabbitmq, elasticsearch,
elasticsearch_http, etc. Workers run in separate threads each handling
events as they come in. This allows you to linearly scale up outputs across
cores or as blocking-io permits.
- grok performance is up 600%
- lots of bug fixes
- bugfixes to conditionals (#682, Matt Dainty)
- rabbitmq now replaces the old deprecated amqp plugins. amqp plugins are
removed.
- inputs will now do their best to handle text which is encoded differently
than the charset you have specified (LOGSTASH-1443, Jordan Sissel)
## inputs
- bugfix: udp: respects teardown requests via SIGINT, etc (LOGSTASH-1290,
Jordan Sissel)
- bugfix: rabbitmq: disable automatic connection recovery (LOGSTASH-1350,
#641, #642; Michael Klishin)
- bugfix: twitter: works again (#640, Bernd Ahlers)
- compatibility: Restored the old 'format' setting behavior. It is still
deprecated, but was accidentally removed in 1.2.0. It will be removed
later, but is restored as part of our backwards-compat promise (Jordan
Sissel)
- bugfix: s3: fix LOGSTASH-1321 and LOGSTASH-1319 (Richard Pijnenburg)
- bugfix: log4j: fix typo (Jordan Sissel)
- bugfix: rabbitmq: disable automatic connection recover because logstash
will handle it (LOGSTASH-1350, Michael Klishin)
- bugfix: heroku: works again (LOGSTASH-1347, #643; Bernd Ahlers)
- bugfix: tcp: improve detection of closed connections to reduce lost events
(Jordan Sissel)
- bugfix: elasticsearch: now works correctly (#670, Richard Pijnenburg)
- improvement: elasticsearch: make size and scroll time configurable (#670,
Richard Pijnenburg)
- improvement: elasticsearch: tunable search type (#670, Richard Pijnenburg)
- compatibility: restore 'format' setting which was accidentally removed in
1.2.0. This feature is still deprecated, but it has been restored
temporarily as part of our backwards compatibility promise. (#706, Jordan
Sissel)
- bugfix: syslog: fix socket leakage (#704, Bernd Ahlers)
- improvement: all aws-related plugins: Add proxy_uri setting (#714, Malthe
Borch)
- bugfix: unix: fix variable name crash (#720, Nikolay Bryskin)
## codecs
- new: graphite: parse graphite formated events (Nick Ethier)
- new: json_lines: parse streams that are lines of json objects (#731, Nick
Ethier)
- bugfix: multiline: time is now correctly in UTC. (Jordan Sissel)
- bugfix: oldlogstashjson: improved conversion of old logstash json to the
new schema (#654, Jordan Sissel)
- bugfix: oldlogstashjson: fix typo breaking encoding (#665, Tom Howe)
- bugfix: json: now assumes json delimited by newline character
(LOGSTASH-1332, #710; Nick Ethier)
- improvements: netflow: new target and versions settings (#686, Matt Dainty)
## filters
- performance: grok: 6.3x performance improvement (#681, Jordan Sissel)
- bugfix: geoip: empty values (nil, empty string) are not put into the event
anymore. (Jordan Sissel)
- bugfix: geoip: allow using Maxmind's ASN database (LOGSTASH-1394, #694;
Bernd Ahlers)
- improvement: kv: target will now overwrite any existing fields, including
the source (Jordan Sissel).
- improvement: Kv: 'prefix' setting now respects sprintf (LOGSTASH-913,
#647; Richard Pijnenburg)
- checksum: sha128 was not a valid digest, removed from list
- feature: metrics: added clear_interval and flush_interval parameters for
setting flush rates and when to clear metrics (#545)
- new: collate: group events by time and/or count into a single event. (#609,
Neway Liu)
- feature: date: now supports a 'target' field for writing the timestamp into
a field other than @timestamp. (#625, Jonathan Van Eenwyk)
- bugfix: riemann: event tagging works again (#631, Marc Fournier)
- improvement: grok: IPV6 pattern (#623, Matt Dainty)
- improvement: metrics: add clear_interval and flush_interval settings (#545,
Juarez Bochi)
- improvement: useragent: include operating system details (#656, Philip
Kubat)
- improvement: csv: new quote_char setting (#725, Alex Markham)
## outputs
- feature: all outputs have a 'worker' setting now that allows you to
perform more work at the same time. This is useful for plugins like
elasticsearch_http, redis, etc, which can bottleneck on waiting for
requests to complete but would otherwise be happy processing more
simultaneous requests. (#708, Jordan Sissel)
- bugfix: elasticsearch: requests are now synchronous. This avoid overloading
the client and server with unlimited in-flight requests. (#688, Jordan
Sissel)
- bugfix: elasticsearch_http: fix bug when sending multibyte utf-8 events
(LOGSTASH-1328, #678, #679, #695; Steve Merrill, Christian Winther,
NickEthier, Jordan Sissel)
- performance: elasticsearch_http: http client library uses TCP_NODELAY now
which dramatically improves performance. (#696, Jordan Sissel)
- feature: elasticsearch_http now supports a 'replication' setting to
allow you to choose how you wait for the response. THe default is 'sync'
which waits for all replica shards to be written. If you set it to 'async'
then all index requests will respond once only the primary shards have been
written and the replica shards will be written later. This can improve
throughput. (#700, Nick Ethier, Jordan Sissel)
- bugfix: elasticsearch: the default port range is now 9300-9305; the older
range up to 9400 was unnecessary and could cause problems for the
elasticsearch cluster in some cases.
- improvement: aws-based outputs (e.g. cloudwatch) now support proxy uri.
- bugfix: rabbitmq: disable automatic connection recovery (LOGSTASH-1350)
(#642)
- bugfix: riemann: fixed tagging of riemann events (#631)
- bugfix: s3: fix LOGSTASH-1321 and LOGSTASH-1319 (#636, #645; Richard
Pijnenburg)
- bugfix: mongodb: Fix mongodb auth (LOGSTASH-1371, #659; bitsofinfo)
- bugfix: datadog: Fix time conversion (LOGSTASH-1427, #690; Bernd Ahlers)
- bugfix: statsd: Permit plain floating point values correctly in the
config. Example: sample_rate => 0.5 (LOGSTASH-1441, #705; Jordan Sissel)
- bugfix: syslog: Fix timestamp date formation. 'timestamp' setting is now
deprecated and the format of the time depends on your rfc selection.
(LOGSTASH-1423, #692, #739; Jordan Sissel, Bernd Ahlers)
## patterns
- improvement: added IPV6 suppot to IP pattern (#623)
1.2.1 (September 7, 2013)
# general
- This is primarily a bugfix/stability release based on feedback from 1.2.0
- web: kibana's default dashboard now works with the new logstash 1.2 schema.
- docs: updated the tutorials to work in logstash 1.2.x
- agent: Restored the --configtest flag (unintentionally removed from 1.2.0)
- deprecation: Using deprecated plugin settings can now advise you on a
corrective path to take. One example is the 'type' setting on filters and
outputs will now advise you to use conditionals and give an example.
- conditionals: The "not in" operator is now supported.
## inputs
- bugfix: pipe: reopen the pipe and retry on any error. (#619, Jonathan Van
Eenwyk)
- bugfix: syslog: 'message' field no longer appears as an array.
- bugfix: rabbitmq: can now bind the queue to the exchange (#624, #628,
LOGSTASH-1300, patches by Jonathan Tron and Jonathan Van Eenwyk)
## codecs
- compatibility: json: if data given is not valid as json will now be used as
the "message" of an event . This restores the older behavior when using
1.1.13's "format => json" feature on inputs. (LOGSTASH-1299)
- new: netflow: process netflow data (#580, patches by Nikolay Bryskin and
Matt Dainty)
## filters
- bugfix: multiline: the multiline filter returns! It was unintentionally
removed from the previous (1.2.0) release.
- bugfix: json_encode: fix a syntax error in the code. (LOGSTASH-1296)
- feature: kv: now captures duplicate field names as a list, so 'foo=bar
foo=baz' becomes the field 'foo' with value ['bar', 'baz'] (an array).
(#622, patch by Matt Dainty)
## outputs
- new: google_cloud_storage: archive logs to Google Cloud Storage (#572,
Rodrigo De Castro)
- bugfix: fixed bug with 'tags' and 'exclude_tags' on outputs that would
crash if the event had no tags. (LOGSTASH-1286)
1.2.0 (September 3, 2013)
# general
- The logstash json schema has changed. (LOGSTASH-675)
For prior logstash users, you will be impacted one of several ways:
* You should check your elasticsearch templates and update them accordingly.
* If you want to reindex old data from elasticsearch with the new schema,
you should be able to do this with the elasticsearch input. Just make
sure you set 'codec => oldlogstashjson' in your elasticsearch input.
- The old logstash web ui has been replaced by Kibana 3. Kibana is a far
superior search and analytics interface.
- New feature: conditionals! You can now make "if this, then ..." decisions
in your filters or outputs. See the docs here:
https://logstash.net/docs/latest/configuration#conditionals
- A new syntax exists for referencing fields (LOGSTASH-1153). This replaces
the prior and undocumented syntax for field access (was 'foo.bar' and is
now '[foo][bar]'). Learn more about this here:
https://logstash.net/docs/latest/configuration#fieldreferences
- A saner hash syntax in the logstash config is now supported. It uses the
perl/ruby hash-rocket syntax: { "key" => "value", ... } (LOGSTASH-728)
- ElasticSearch version 0.90.3 is included. (#486, Gang Chen)
- The elasticsearch plugin now uses the bulk index api which should result
in lower cpu usage as well as higher performance than the previous
logstash version.
- Many deprecated features have been removed. If your config caused
deprecation warnings on startup in logstash v1.1.13, there is a good
chance that these deprecated settings are now absent.
- 'type' is no longer a required setting on inputs.
- New plugin type: codec. Used to implement decoding of events for inputs and
encoding of events for outputs. Codecs allow us to separate transport (like
tcp, redis, rabbitmq) from serialization (gzip text, json, msgpack, etc).
- Improved error messages that try to be helpful. If you see bad or confusing
error messages, it is a bug, so let us know! (Patch by Nick Ethier)
- The old 'plugin status' concept has been replaced by 'milestones'
(LOGSTASH-1137)
- SIGHUP should cause logstash to reopen it's logfile if you are using the
--log flag

## Overview of this release:
- new inputs: drupal_dblog.
- new filters: anonymize, metrics.
- new outputs: syslog, cloudwatch.
- new 'charset' setting for all inputs. This should resolve all known encoding
problems. The default charset is UTF-8.
- grok now captures (?<somename>...) regexp into 'somename' field
- Elasticsearch 0.20.2 is included. This means you are required to upgrade
your elasticsearch cluster to 0.20.2. If you wish to continue using an old
version of elasticsearch, you should use the elasticsearch_http plugin
instead of the elasticsearch one.
## general
- fixed internal dependency versioning on 'addressable' gem (LOGSTASH-694)
- fixed another case of 'watchdog timeout' (LOGSTASH-701)
- plugin flags are now deprecated. The grok filter (--grok-pattern-path) was

## inputs
- All inputs now have a 'charset' setting to help you inform logstash of the
text encoding of the input. This is useful if you have Shift_JIS or CP1251
encoded log files. This should help resolve the many UTF-8 bugs that were
reported recently. The default charset is UTF-8.
- new: drupal_dblog: read events from a DBLog-enabled Drupal. (#251, Patch by
theduke)
- bugfix: zeromq: 'topology' is now a required setting
- bugfix: lumberjack: client connection closing is now handled properly.
(Patch by Nick Ethier)
- misc: lumberjack: jls-lumberjack gem updated to 0.0.7
- bugfix: stomp: fix startup problems causing early termination (#226
- bugfix: tcp: the 'source host' for events is now the client ip:port that
sent it, instead of the listen address that received it. (LOGSTASH-796)
- improvement: tcp: the default data_timeout is now -1 (never timeout).
This change was made because read timeouts were causing data loss, and
logstash should avoid losing events by default.
- improvement: amqp: the 'name' setting is now called 'queue' (#274)
- improvement: eventlog: the 'name' setting is now called 'logfile' (#274)
- bugfix: log4j: fix stacktrace reading (#253, patch by Alex Arutyunyants)
## filters
- new: anonymize: supports many hash mechanisms (murmur3, sha1, md5, etc) as
well as IP address anonymization (#280, #261; patches by Richard Pijnenburg
and Avishai Ish-Shalom)
- new: metrics: allows you to aggregate metrics from events and emit them
periodically. Think of this like 'statsd' but implemented as a logstash
filter instead of an external service.
- feature: date: now accepts 'match' as a setting. Use of this is preferable
to the old syntax. Where you previously had 'date { somefield =>
"somepattern" }' you should now do: 'date { match => [ "somefield",
"somepattern" ] }'. (#248, LOGSTASH-734, Patch by Louis Zuckerman)
- feature: grok: now accepts (?<foo>...) named captures. This lets you
compose a pattern in the grok config without needing to define it in a
patterns file. Example: (?<hostport>%{HOST}:%{POSINT}) to capture 'hostport'
- improvement: grok: allow '$' in JAVACLASS pattern (#241, patch by Corry
Haines)
- improvement: grok: can now match against number types. Example, if you're
sending a json format event with { "status": 403 } you can now grok that
field. The number is represented as a string "403" before pattern matching.
- bugfix: date: Fix a bug that would crash the pipeline if no date pattern
matched. (LOGSTASH-705)
- feature: kv: Adds field_split, value_split, prefix, and container
settings. (#225, patch by Alex Wheeler)
- bugfix: mutate: rename on a nonexistant field now does nothing as expected.
(LOGSTASH-757)
- bugfix: grok: don't tag an event with _grokparsefailure if it's already so
(#248, patch by Greg Brockman)
- feature: mutate: new settings - split, join, strip. "split" splits a field
into an array. "join" merges an array into a string. "strip" strips leading and
trailing whitespace. (Patch by Avishai Ish-Shalom)
## outputs
- new: syslog output supporting both RFC3164 and RFC5424 (#180, patch by
Rui Alves)
- new: cloudwatch output to emit metrics and other events to Amazon CloudWatch.
(LOGSTASH-461, patch by Louis Zuckerman)
- feature: stdout: added 'message' setting for configuring the output message
format. The default is same behavior as before this feature.
- feature: http: added 'format' option to select 'json' or form-encoded
request body to send with each request.
- feature: http: added 'content_Type' option set the Content-Type header.
This defaults to "application/json" if the 'format' is 'json'. Will default
to 'application/x-www-form-urlencoded' if the 'format' is 'form'
- bugfix: zeromq: 'topology' is now a required setting
- feature: mongodb: new setting 'isodate' that, when true, stores the
@timestamp field as a mongodb date instead of a string. (#224, patch by
Kevin Amorin)
- improvement: gelf: Allow full_message gelf property to be overridden (#245,
patch by Sébastien Masset)
- misc: lumberjack: jls-lumberjack gem updated to 0.0.6
- feature: nagios: New 'nagios_level' setting to let you change the level
of the passive check result sent to nagios. (#298, Patch by James Turnbull)
- feature: elasticsearch, elasticsearch_http, elasticsearch_river: new setting
'document_id' for explicitly setting the document id in each write to
elasticsearch. This is useful for overwriting existing documents.
- improvement: elasticsearch_river: 'name' is now 'queue' (#274)
- improvement: amqp: 'name' is now 'exchange' (#274)
- bugfix: the websocket output works again (supports RFC6455)
1.1.5 (November 10, 2012)
## Overview of this release:
* New inputs: zenoss, gemfire
* New outputs: lumberjack, gemfire
* Many UTF-8 crashing bugs were resolved
## general
- new runner command 'rspec' - lets you run rspec tests from the jar
This means you should now be able to write external tests that execute your
logstash configs and verify functionality.
- "file not found" errors related to paths that had "jar:" prefixes should
now work. (Fixes LOGSTASH-649, LOGSTASH-642, LOGSTASH-655)
- several plugins received UTF-8-related fixes (file, lumberjack, etc)
File bugs if you see any UTF-8 related crashes.
- 'json_event' format inputs will now respect 'tags' (#239, patch by
Tim Laszlo)
- logstash no longer uses nor recommends bundler (see 'gembag.rb'). The
Gemfile will be purged in the near future.
- amqp plugins are now marked 'unsupported' as there is no active maintainer
nor is there source of active support in the community. If you're interested
in maintainership, please email the mailling list or contact Jordan!

1.1.1 (July 14, 2012)
## Overview of this release:
* New input plugins: generator, heroku, pipe, ganglia, irc
* New output plugins: juggernaut, metricscatcher, nagios_ncsa, pipe,
opentsdb, pagerduty, irc
* New filter plugins: zeromq, environment, xml, csv, syslog_pri
* Fixes for gelf output
* Support for more than 1 filter worker (agent argument "-w")
## IMPORTANT CHANGES FOR UPGRADES FROM 1.1.0
- zeromq input and output rewritten
The previous zeromq support was an MVP. It has now been rewritten into
something more flexible. The configuration options have changed entirely.
While this is still listed as `experimental`, we don't predict any more
configuration syntax changes. The next release will bump this to beta.
- unix_timestamp
Previously, several plugins did not work as expected on MRI due to the
usage of the JRuby-only Jodatime library. We now have a contributed fix
for a slower parser on MRI/CRuby!
- elasticsearch version is now 0.19.8
This means your elasticsearch cluster must be running 0.19.x for
compatibility reasons.
- grok pattern %{POSINT} used to match '0' -- now it does not. If you want
to match non-negative integers, there is now a %{NONNEGINT} pattern.
- bug in file input fixed that led to an extra leading slash in @source_path.
Previously, file input would have @source = 'file://host//var/log/foo' and
@source_path = '//var/log/foo'; now @source = 'file://host/var/log/foo'
and @source_path = '/var/log/foo'. [LOGSTASH-501]
- file input now rejects relative paths. [LOGSTASH-503]
- event sprintf can now look inside structured field data. %{foo.bar} will
look in the event field "foo" (if it is a hash) for "bar". To preserve
compatibility, we first look for a top-level key that matches exactly
(so %{foo.bar} will first look for a field named "foo.bar", then look for
"bar" under "foo").
## general
- NOTE: gemspec removed; deploying logstash as a gem hasn't been supported
for a while.
- feature: logstash sub-commands "irb" and "pry" for an interactive debug
console, useful to debug jruby when running from the monolithic jar
- misc: newer cabin gem for logging
- misc: initial support for reporting internal metrics (currently outputs
to INFO log; eventually will be an internal event type)
- misc: added a "thread watchdog" to detect hanging filter workers, and
crash logstash w/an informational message
- misc: jar is built with jruby 1.6.7.2
- misc: better shutdown behavior when there are no inputs/plugins running
- feature: logstash web now uses relative URLs; useful if you want to
reverseproxy with a path other than "/"
## inputs
- bugfix: stdin: exit plugin gracefully on EOF
- feature: [LOGSTASH-410] - inputs can now be duplicated with the
'threads' parameter (where supported)
- bugfix: [LOGSTASH-490] - include cacert.pem in jar for twitter input
- feature: [LOGSTASH-139] - support for IRC
## filters
- feature: all filters support 'remove_tag' (remove tags on success)
- feature: all filters support 'exclude_tags' (inverse of 'tags')
- bugfix: [LOGSTASH-300] - bump grok pattern replace limit to 1000,
fixes "deep recursion pattern compilation" problems
- bugfix: [LOGSTASH-375] - fix bug in grep: don't drop when field is nil
and negate is true
- bugfix: [LOGSTASH-386] - fix some grok patterns for haproxy
- bugfix: [LOGSTASH-446] - fix grok %{QUOTEDSTRING} pattern, should fix
some grok filter hangs
- bugfix: some enhancements to grok pattern %{COMBINEDAPACHELOG}
- bugfix: grok: %{URIPATH} and %{URIPARAM} enhancements
- feature: grok: add %{UUID} pattern
- bugfix: grok: better error message when expanding unknown %{pattern}
- feature: mutate: now supports a 'gsub' operation for applying a regexp
substitution on event fields
## outputs
- bugfix: [LOGSTASH-351] - fix file input on windows
- feature: [LOGSTASH-356] - make file output flush intervals configurable
- feature: [LOGSTASH-392] - add 'field' attribute to restrict which fields
get sent to an output
- feature: [LOGSTASH-374] - add gzip support to file output
- bugfix: elastic search river now respects exchange_type and queue_name
- bugfix: ganglia plugin now respects metric_type
- bugfix: GELF output facility fixes; now defaults to 'logstash-gelf'
- feature: [LOGSTASH-139] - support for IRC
- bugfix: es_river: check river status after creation to verify status
- feature: es: allow setting node_name
- feature: redis: output batching for list mode
1.1.0.1 (January 30, 2012)
## Overview of this release:
* date filter bugfix: [LOGSTASH-438] - update joda-time to properly
handle leap days
1.1.0 (January 30, 2012)
## Overview of this release:
* New input plugins: zeromq, gelf
* New filter plugins: mutate, dns, json
* New output plugins: zeromq, file
* The logstash agent now runs also in MRI 1.9.2 and above
This is a large release due to the longevity of the 1.1.0 betas.
We don't like long releases and will try to avoid this in the future.
## IMPORTANT CHANGES FOR UPGRADES FROM 1.0.x
- grok filter: named_captures_only now defaults to true
This means simple patterns %{NUMBER} without any other name will
now not be included in the field set. You can revert to the old
behavior by setting 'named_captures_only => false' in your grok
filter config.
- grok filter: now uses Ruby's regular expression engine
The previous engine was PCRE. It is now Oniguruma (Ruby). Their
syntaxes are quite similar, but it is something to be aware of.
- elasticsearch library upgraded to 0.18.7
This means you will need to upgrade your elasticsearch servers,
if any, to the this version: 0.18.7
- AMQP parameters and usage have changed for the better. You might
find that your old (1.0.x) AMQP logstash configs do not work.
If so, please consult the documentation for that plugin to find
the new names of the parameters.
## general
- feature: [LOGSTASH-158] - MRI-1.9 compatible (except for some
plugins/functions which will throw a compatibility exception) This means
you can use most of the logstash agent under standard ruby.
- feature: [LOGSTASH-118] - logstash version output (--version or -V for
agent)
- feature: all plugins now have a 'plugin status' indicating the expectation
of stability, successful deployment, and rate of code change. If you
use an unstable plugin, you will now see a warning message on startup.
- bugfix: AMQP overhaul (input & output), please see docs for updated
config parameters.
- bugfix: [LOGSTASH-162,177,196] make sure plugin-contained global actions
happen serially across all plugins (with a mutex)
- bugfix: [LOGSTASH-286] - logstash agent should not truncate logfile on
startup
- misc: [LOGSTASH-160] - now use gnu make instead of rake.
- misc: now using cabin library for all internal logging
- test: use minitest
- upgrade: now using jruby in 1.9 mode
## inputs
- feature: zeromq input. Requires you have libzmq installed on your system.
- feature, bugfix: [LOGSTASH-40,65,234,296]: much smarter file watching for
file inputs. now supports globs, keeps state between runs, can handle
truncate, log rotation, etc. no more inotify is required, either (file
input now works on all platforms)
- feature: [LOGSTASH-172,201] - syslog input accepts ISO8601 timestamps
- feature: [LOGSTASH-159] - TCP input lets you configure what identifies
an input stream to the multiline filter (unique per host, or connection)
- feature: [LOGSTASH-168] - add new GELF input plugin
- bugfix: [LOGSTASH-8,233] - fix stomp input
- bugfix: [LOGSTASH-136,142] - file input should behave better with log rotations
- bugfix: [LOGSTASH-249] - Input syslog force facility type to be an integer
- bugfix: [LOGSTASH-317] - fix file input not to crash when a file
is unreadable
## filters
- feature: [LOGSTASH-66,150]: libgrok re-written in pure ruby (no more
FFI / external libgrok.so dependency!)
- feature: [LOGSTASH-292,316] - Filters should run on all events if no condition
is applied (type, etc).
- feature: [LOGSTASH-292,316] - Filters can now act on specific tags (or sets
of tags).
- bugfix: [LOGSTASH-285] - for grok, add 'keep_empty_captures' setting to
allow dropping of empty captures. This is true by default.
- feature: [LOGSTASH-219] - support parsing unix epoch times
- feature: [LOGSTASH-207] - new filter to parse a field as json merging it
into the event.
- feature: [LOGSTASH-267,254] - add DNS filter for doing forward or
reverse DNS on an event field
- feature: [LOGSTASH-57] - add mutate filter to help with manipulating
event field content and type
## outputs
- feature: zeromq output. Requires you have libzmq installed on your system.
- feature: new file output plugin
- bugfix: [LOGSTASH-307] embedded elasticsearch now acts as a full ES server;
previously embedded was only accessible from within the logstash process.
- bugfix: [LOGSTASH-302] - logstash's log level (-v, -vv flags) now control
the log output from the elasticsearch client via log4j.
- bugfix: many gelf output enhancements and bugfixes
- feature: [LOGSTASH-281] - add https support to loggly output
- bugfix: [LOGSTASH-167] - limit number of in-flight requests to the
elasticsearch node to avoid creating too many threads (one thread per
pending write request)
- bugfix: [LOGSTASH-181] - output/statsd: set sender properly
- bugfix: [LOGSTASH-173] - GELF output can throw an exception during gelf notify
- bugfix: [LOGSTASH-182] - grep filter should act on all events if no type is
specified.

- Bugs fixed
- [LOGSTASH-147] - grok filter incorrectly adding fields when a match failed
- [LOGSTASH-151] - Fix bug in routing keys on AMQP
- [LOGSTASH-156] - amqp issue with 1.0.16?
- Improvement
- [LOGSTASH-148] - AMQP input should allow queue name to be specified separately from exchange name
- [LOGSTASH-157] - Plugin doc generator should make regexp config names more readable
- New Feature
- [LOGSTASH-153] - syslog input: make timestamp an optional field
- [LOGSTASH-154] - Make error reporting show up in the web UI
1.0.16 (Aug 18, 2011)
- Fix elasticsearch client problem with 1.0.15 - jruby-elasticsearch gem
version required is now 0.0.10 (to work with elasticsearch 0.17.6)
1.0.15 (Aug 18, 2011)
- IMPORTANT: Upgraded to ElasticSearch 0.17.6 - this brings a number of bug
fixes including an OOM error caused during high index rates in some
conditions.
NOTE: You *must* use same main version of elasticsearch as logstash does,
so if you are still using elasticsearch server 0.16.x - you need to upgrade
your server before the elasticsearch output will work. If you are using
the 'embedded' elasticsearch feature of logstash, you do not need to make
any changes.
- feature: tcp input and output plugins can now operate in either client
(connect) or server (listen) modes.
- feature: new output plugin "statsd" which lets you increment or record
timings from your logs to a statsd agent
- feature: new redis 'pattern_channel' input support for PSUBSCRIBE
- feature: new output plugin "graphite" for taking metrics from events and
shipping them off to your graphite/carbon server.
- feature: new output plugin "ganglia" for shipping metrics to ganglia
gmond server.
- feature: new output plugin "xmpp" for shipping events over jabber/xmpp
- feature: new input plugin "xmpp" for receiving events over jabber/xmpp
- feature: amqp input now supports routing keys.
https://logstash.jira.com/browse/LOGSTASH-122
- feature: amqp output now supports setting routing key dynamically.
https://logstash.jira.com/browse/LOGSTASH-122
- feature: amqp input/output both now support SSL.
https://logstash.jira.com/browse/LOGSTASH-131
- feature: new input plugin "exec" for taking events from executed commands
like shell scripts or other tools.
- feature: new filter plugin "split" for splitting one event into multiple.
It was written primarily for the new "exec" input to allow you to split
the output of a single command run by line into multiple events.
- misc: upgraded jar releases to use JRuby 1.6.3
- bugfix: syslog input shouldn't crash anymore on weird network behaviors
like portscanning, etc.
https://logstash.jira.com/browse/LOGSTASH-130
1.0.14 (Jul 1, 2011)
- feature: new output plugin "loggly" which lets you ship logs to loggly.com
- feature: new output plugin "zabbix" - similar to the nagios output, but
works with the Zabbix monitoring system. Contributed by Johan at
Mach Technology.
- feature: New agent '-e' flag which lets you specify a config in a string.
If you specify no 'input' plugins, default is stdin { type => stdin }
If you specify no 'output' plugins, default is stdout { debug => true }
This is intended to be used for hacking with or debugging filters, but
you can specify an entire config here if you choose.
- feature: Agent '-f' flag now supports directories and globs. If you specify
a directory, all files in that directory will be loaded as a single config.
If you specify a glob, all files matching that glob will be loaded as a
single config.
- feature: gelf output now allows you to override the 'sender'. This defaults
to the source host originating the event, but can be set to anything now.
It supports dynamic values, so you can use fields from your event as the
sender. Contributed by John Vincent
Issue: https://github.com/logstash/logstash/pull/30
- feature: added new feature to libgrok that allows you to define patterns
in-line, like "%{FOO=\d+}" defines 'FOO' match \d+ and captures as such.
To use this new feature, you must upgrade libgrok to at least 1.20110630
Issue: https://logstash.jira.com/browse/LOGSTASH-94
- feature: grok filter now supports 'break_on_match' defaulting to true
(this was the original behavior). If you set it to false, it will attempt
to match all patterns and create new fields as normal. If left default
(true), it will break after the first successful match.
- feature: grok filter now supports parsing any field. You can do either of
these: grok { match => [ "fieldname", "pattern" ] }
or this: grok { fieldname => "pattern" }
The older 'pattern' attribute still means the same thing, and is equivalent
to this: grok { match => [ "@message", "pattern" ] }
Issue: https://logstash.jira.com/browse/LOGSTASH-101
- feature: elasticsearch - when embedded is true, you can now set the
'embedded_http_port' to configure which port the embedded elasticsearch
server listens on. This is only valid for the embedded elasticsearch
configuration. https://logstash.jira.com/browse/LOGSTASH-117
- bugfix: amqp input now reconnects properly when the amqp broker restarts.
- bugfix: Fix bug in gelf output when a fields were not arrays but numbers.
Issue: https://logstash.jira.com/browse/LOGSTASH-113
- bugfix: Fix a bug in syslog udp input due to misfeatures in Ruby's URI
class. https://logstash.jira.com/browse/LOGSTASH-115
- misc: jquery and jquery ui now ship with logstash; previously they were
loaded externally
- testing: fixed some bugs in the elasticsearch test itself, all green now.
- testing: fixed logstash-test to now run properly
1.0.12 (Jun 9, 2011)
- misc: clean up some excess debugging output
- feature: for tcp input, allow 'data_timeout => -1' to mean "never time out"
1.0.11 (Jun 9, 2011)
- deprecated: The redis 'name' and 'queue' options for both input and output
are now deprecated. They will be removed in a future version.
- feature: The redis input and output now supports both lists and channels.
- feature: Refactor runner to allow you to run multiple things in a single
process. You can end each instance with '--' flag. For example, to run one
agent and one web instance:
% java -jar logstash-blah.jar agent -f myconfig -- web
- feature: Add 'embedded' option to the elasticsearch output:
elasticsearch { embedded => true }
Default is false. If true, logstash will run an elasticsearch server
in the same process as logstash. This is really useful if you are just
starting out or only need one one elasticsearch server.
- feature: Added a logstash web backend feature for elasticsearch that tells
logstash to use the 'local' (in process) elasticsearch:
--backend elasticsearch:///?local
- feature: Added 'named_captures_only' option to grok filter. This will have
logstash only keep the captures you give names to - for example %{NUMBER}
won't be kept, but %{NUMBER:bytes} will be.
- feature: Add 'bind_host' option to elasticsearch output. This lets you choose the
address ElasticSearch client uses to bind to - useful if you have a
multihomed server.
