Hello ( @Levi_Turner )
I have a cluster of 2 nodes (master and slave)
In each of the servers : all services are running.. (so difficult to differenciate that way)
The question is, based on the host name (maybe?) , how to know which server is the central and which is the node?
I'm planning to upgrade the servers.. so It's mandatory for me to pinpoint which is what.
Thanks
The easiest way would be to expose the Central Node column in the nodes section of the QMC:
So you've set up DNS aliases for the underlying servers and do not know which alias is which server? This isn't answerable in Qlik Sense and it's piggy backing on the networking in the environment. I'd go this approach
cmd.exe:
ping qliksensecentral.corp.inpkg.net
> note the IP
ping LB01
> note the IP
ping LB02
> note the IP
If it's a simple DNS alias, then you should have an IP address match for either the 01 or 02 servers. If you are using a network appliance to provide the DNS alias, then it won't and you'd need to check with your colleagues who administer those devices to determine what server(s) are in the back-end pool.

That's not what I'm looking for.
In fact, I have 2 servers : LBN01 et LBN02; I want to know which server is central and which one is RIM.
The Central node is the server listed as Central = Yes in the above screenshot. The RIM node(s) is any other node listed.
Thank you Levi but still.. that's not what I'm asking for
We have 2 servers LB01 and LB02 in which we have installed 2 qlik sense servers (CENTRAL and RIM)
I know that the host name : qliksensecentral is the central node but i don't know wheither it's the LB01 or LB02 server.
Why am I looking for this? To know in which order I'll do the upgrade (stop the rim services then central etc)..
