Hello rb,
Service discovery you mean full scan and automatic refresh (rasa) that Is done after changng the port in the check rule for elastic search .
After that host is showing ping issue .
every service of the host gone to unknown .
If we are giving port as 9200 in check rule for elastic search and doing full scan and refresh and activate affected changes , all other service move to unknown and only shows ping service only below is the screenshot for the same.
showing ping service only . Not any other service
