Disable logs for solr healthchecks

9/19/2018

I'm currently running a distributed solr cloud with Kubernetes.

I have configured a liveness probe with kubernetes which always restarts the solr pod if the liveness probe fails.

solr healthckeck -c collection-name

This works very well, except that every time when a liveness probe gets performed, solr logs this request (currently 4 lines of log output). The liveness probe gets executed every 10 seconds, so the whole log file consists of this healthcheck messages and real useful messages disappear or can hardly be found.

Does anyone know if there is a way in solr to disable these healthcheck messages/logs?

You can just set up a filter on your Solr log4j2 configs:

Something like:

  <Loggers>
    <Root level="INFO">
      <RegexFilter regex=".*something-that-matches-the-liveness-probe.*" onMatch="DENY" onMismatch="NEUTRAL"/>
    </Root>
  </Loggers>

Hope it helps!
