This functionality is experimental and may be changed or removed completely in a future release. Elastic will take a best effort approach to fix any issues, but experimental features are not subject to the support SLA of official GA features.
The node stats API retrieves runtime stats about Logstash.
GET /_node/stats/<types>
Where <types> is optional and specifies the types of stats you want to return.
By default, all stats are returned. You can limit the info that’s returned by combining any of the following types in a comma-separated list:
|
|
Gets JVM stats, including stats about threads, memory usage, and garbage collectors. |
|
|
Gets process stats, including stats about file descriptors, memory consumption, and CPU usage. |
|
|
Gets runtime stats about the Logstash pipeline. |
The following request returns a JSON document containing JVM stats:
