Mastering Microservices with Java - Third Edition

Pushing logs to the ELK Stack

We are done making the ELK Stack available for consumption. Now, Logstash just needs a log stream that can be indexed by Elasticsearch. Once the Elasticsearch index of logs is created, logs can be accessed and processed on the Kibana dashboard.

To push the logs to Logstash, we need to make the following changes in our service code. We need to add logback and logstash-logback encoder dependencies in OTRS services.

Add the following dependencies in the pom.xml file:

... <dependency> <groupId>net.logstash.logback</groupId> <artifactId>logstash-logback-encoder</artifactId> <version>4.6</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-core</artifactId> <version>1.1.9</version> ...
