I have 3 Node Search Head Cluster member with ITSI app. This environment is operational .
Now we added 3 more Search Head Cluster Member.
How can I confirm that newly added SHC member is in synch with others for ITSI app?

Here is After that we confirmed that all the members are in cluster using command

$SPLUNK_HOME/bin/splunk show shcluster-status
$SPLUNK_HOME/bin/splunk show kvstore-status

To confirm if itsi looked good , login to the new SHC member and navigated to ITSI app and in this App under configuration>Services and here count the ## of services ( i.e this should match with old SHC member)

In addition, navigated navigate to Setting>”Search and Report” verify KPI indicators like “>[Indicator - 3e6a914db63fa245b5df5358 - ITSI Search]”
