When you run Logstash, it automatically captures runtime metrics that you canuse to monitor the health and performance of your Logstash deployment.
The metrics collected by Logstash include:
- Logstash node info, like pipeline settings, OS info, and JVM info.
- Plugin info, including a list of installed plugins.
- Node stats, like JVM stats, process stats, event-related stats, and pipelineruntime stats.
- Hot threads.
You can use the basic monitoring APIs provided by Logstashto retrieve these metrics. These APIs are available by default withoutrequiring any extra configuration.
Alternatively, you can configure X-Pack monitoring to senddata to a monitoring cluster.
Monitoring is an X-Pack feature under the Basic License and is thereforefree to use.
You can use the monitoring UI in X-Pack to view themetrics and gain insight into how your Logstash deployment is running.
The pipeline viewer in X-Pack offers additionalvisibility into the behavior and performance of complex pipeline configurations.It shows a graph representation of the overall pipeline topology, data flow, andbranching logic, overlaid with important metrics, like events per second, foreach plugin in the view.
This documentation focuses on the X-Pack monitoring infrastructure and setup inLogstash. For an introduction to monitoring your Elastic stack, including Elasticsearchand Kibana, see Monitoring the Elastic Stack.
