Get node stats

GET /_node/stats

Get runtime stats for Logstash, where <types> (optional) specifies the types of stats you want to return. You can limit the info that is returned by combining any of these types in a comma-separated list:

  • jvm gets JVM stats, including stats about threads, memory usage, garbage collectors, and uptime.
  • process gets process stats, including stats about file descriptors, memory consumption, and CPU usage.
  • events gets event-related statistics for the Logstash instance (regardless of how many pipelines were created and destroyed).
  • flow gets flow-related statistics for the Logstash instance (regardless of how many pipelines were created and destroyed).
  • pipelines gets runtime stats about each Logstash pipeline.
  • reloads gets runtime stats about config reload successes and failures.
  • os gets runtime stats about cgroups when Logstash is running in a container.
  • geoip_download_manager gets stats for databases used with the Geoip filter plugin.

Query parameters

  • pretty boolean

    If you append ?pretty=true to the request, the JSON returned will be pretty formatted (use it for debugging only!).
