We have two PRTG servers set up in a cluster (they are in separate data centres for resilience), but have now hit performance issues with the probes and they are complaining of too many open requests.
I would like to add two additional servers as probes for our cluster to distribute the load and keep the resilience of the cluster i.e. if one side fails, the other continues monitoring just as it is now. How is this done?
As a test I have added the two servers as simply additional probes, but I don't think this is what I needed to do, perhaps I should have enlarged the cluster?
