--------------------------------------------

             Summary: Implement trigger for arbitrary metrics
                 Key: SOLR-11201
                 URL: https://issues.apache.org/jira/browse/SOLR-11201
             Project: Solr
          Issue Type: Sub-task
      Security Level: Public (Default Security Level. Issues are Public)
          Components: AutoScaling, SolrCloud
            Reporter: Shalin Shekhar Mangar
             Fix For: 7.2


It should be possible to set a trigger on any metrics exposed by the Metrics API using a threshold
value. Supporting {{waitFor}} may not be possible or useful for all metrics. For those we
will implement proper trigger support (such as searchRate) However, a naive implementation
might be to just poll the value of the metric frequently and if it is consistently above the
threshold, fire the trigger.
