Sentry Logback

Motivation

Grouping logging events by logger name. It's useful than you have log messages without stack trace:

WARN  [2019-09-28 10:51:32,371] [qwerty-akka.actor.default-dispatcher-26] a.h.i.e.c.PoolGateway: Connection attempt failed. Backing off new connection attempts for at least 200 milliseconds.

Usage

Dependency

To resolve artifacts through Artifactory, simply add the following code snippet to your pom.xml file:

    <repositories>
        <repository>
            <id>jcenter</id>
            <name>jcenter</name>
            <url>https://jcenter.bintray.com</url>
        </repository>
    </repositories>

Choose dependency snippet:

    <dependency>
        <groupId>com.github.andriimartynov</groupId>
        <artifactId>sentry-logback</artifactId>
        <version>1.7.30</version>
        <type>pom</type>
    </dependency>

Add sentry appender to your logback.xml:

<configuration>
    <!-- Configure the Console appender -->
    <appender name="Console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

    <!-- Configure the Sentry appender, overriding the logging threshold to the WARN level -->
    <appender name="Sentry" class="com.github.andriimartynov.logback.SentryAppender">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>WARN</level>
        </filter>
    </appender>

    <!-- Enable the Console and Sentry appenders, Console is provided as an example
 of a non-Sentry logger that is set to a different logging threshold -->
    <root level="INFO">
        <appender-ref ref="Console" />
        <appender-ref ref="Sentry" />
    </root>
</configuration>
