Fundamental problems in PRTG installation after Master Slave move



Hi I used this link ( https://kb.paessler.com/en/topic/413-how-can-i-move-migrate-my-prtg-installation-to-another-computer ) to move my Master PRTG to a Slave PRTG but I don't see that the migration was successfully completed.

While logging in to the Web GUI I see this message:

“…Warning Monitoring may be incomplete or inaccurate due to fundamental problems in your PRTG installation!...”

When I check the Server configuration I still can see the old Master PRT still active but not started. More still the FQDN used is not available and I got to use the new server name instead.

Could You please help me to get this going, thank you.

the article referenced only describes to move a PRTG installation itself but not how to move a master cluster node to failover. In your case I would recommend reactivating the old master node and then breaking up the cluster on both nodes. Afterwards you can move your master to failover and if wanted re-establish a cluster. See this article for details.
Best regards

In some cases this message appear to all PRTG users: “…Warning Monitoring may be incomplete or inaccurate due to fundamental problems in your PRTG installation!...”

I know about this (i Shut Down Failover Node) and i don't want to this message showing to every user. How i can Disable it?

Hi there,

If you plan to leave the Failover Node offline, then please consider reverting PRTG back to a standalone installation. This will also save a lot of resources.

Best regards.
