DMC protocol/port used to check indexers status?

gdigrego
Path Finder

Hello,

Since we have moved our indexers cluster servers behind a firewall, the DMC is showing all indexers as "unreachable" in the "Overview" and "Instances" dashboards ...

But the "Indexer Clustering: Status" dashboard shows them all with Status "Up".

I guess this is due to missing opening a particular protocol/port on our indexer cluster firewall. Which rule shall we add?

To be complete Port TCP 8089 is already open in the index cluster firewall rules

Thanks for you help
