• Linode Exporter

Development Installation

go get github.com/DazWilkin/linode-exporter

Then:

LINODE_TOKEN=[[YOUR-LINODE-API-TOKEN]]
ENDPOINT=":9388"
METRICS="/metrics"

go run github.com/DazWilkin/linode-exporter \
--endpoint=${ENDPOINT} \
--path=${METRICS}

Run-only Installation

Linode Exporter only

Either:

LINODE_TOKEN=[[LINODE-API-TOKEN]]
PORT=9388
docker run \
--interactive \
--tty \
-e LINODE_TOKEN=${LINODE_TOKEN} \
--publish=${PORT}:${PORT} \
ghcr.io/dazwilkin/linode-exporter:b775c09c2d7dca994fccfb662f0b347864d21d30

The exporter's metrics endpoint will be available on http://localhost:${PORT}/metrics

Linode Exporter with Prometheus, AlertManager and cAdvisor

NB AlertManager integration is a work-in-progress

The following

LINODE_TOKEN=[[LINODE-API-TOKEN]]
docker-compose --file=${PWD}/docker-compose.yaml up

You may check the state of the services using:

docker-compose ps

And logs for a specific service using, e.g.:

docker-compose logs linode-exporter

The following endpoints are exposed:

• Linode-Exporter metrics: http://localhost:9388/metrics
• Prometheus UI: http://localhost:9090
• AlertManager UI: http://localhost:9093
• cAdvisor UI: http://localhost:8085

NB cAdvisor is mapped to :8085 rather than it's default port :8080

Using the Prometheus UI, you may begin querying metrics by typing linode_ to see the available set.

The full list is below.

Collectors are instantiated by main.go with registry.MustRegister(NewSomethingCollector(linodeClient))

The [name].go collector implements Prometheus' Collector interface: Collect and Describe
