["ASF GitHub Bot (Jira)" <ji...@apache.org>]

ASF GitHub Bot commented on TIKA-3327:
--------------------------------------

Subhajitdas298 opened a new pull request #417:
URL: https://github.com/apache/tika/pull/417


   For TIKA-3327,
   
   Added very simple MBean for exposing ServerStatus (over an abstraction to enable readonly).
   
   This is **activated when status is enabled** using command line.
   
   This can be used along side Prometheus JMX exporter (or other tool like Jconsole).
   
   Sample Prometheus JMX exporter usage:
   
   Standalone: _java -javaagent:./jmx_prometheus_javaagent-0.15.0.jar=8080:../config/jmx-config.yaml -jar .\tika-server-1.26-SNAPSHOT.jar -status_
   
   Parent-Child mode: _java -cp .\tika-server-1.26-SNAPSHOT.jar org.apache.tika.server.TikaServerCli -status -spawnChild -Jjavaagent:./jmx_prometheus_javaagent-0.15.0.jar=8080:../config/jmx-config.yaml_
   
   Note: MBean works irrespective of java execution mode (-jar or -cp ..Cli). And JMX exporter by default exposes a lot of JVM metrices.

> Currently only  /status endpoint is there as a simple monitoring endpoint. This can not be used directly as part of standard monitoring systems available.
> But no JMX MBeans or any other endpoint is there.
>  
> The status data can be exposed as an MBean.
>  
> This MBean can be then used by, something like Prometheus JMX exporter to export to Prometheus.
