We have upgraded our Elastic to 7.12. And after the upgradation, we can see that when we add any new host in heartbeat/SNMP, the newly added host can be seen in Discover, but cannot find that host from dashboard using the same index pattern (we are using control visualization to select the hosts from drop down). The newly added host can only be seen in the dashboard once a new indice is created which is set to be monthly.
This problem was not in elastic 7.11 but can be see after upgrading to elastic 7.12. Please help me to fix this so that the new host occurs in dashboard as well once added to server.
Thanks a lot.
