# Logstash APIs

When you run Logstash, it automatically captures runtime metrics that you can use to monitor the health and performance of your Logstash deployment.
The metrics collected by Logstash include:

- Health report.
- Hot threads.
- Logstash node info, like pipeline settings, OS info, and JVM info.
- Node stats, like JVM stats, process stats, event-related stats, and pipeline runtime stats.
- Plugins info, including a list of installed plugins.


The APIs that retrieve these metrics are available by default, with no extra configuration needed.
