["Sumit Mohanty (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMBARI-18986?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15693891#comment-15693891 ] 

Sumit Mohanty commented on AMBARI-18986:
----------------------------------------

Modifying the logic to perform cache update only for EXECUTION_COMMANDs (Start/Stop/etc) even though its only needed for METRICS_GRAFANA start. Also we need to figure out a design where agent does not need logic that is specific to a service/component.
