I now have about 200 servers that I am monitoring, all of these created with a template. So far so good - however now I need to change the trigger value of a memory sensor on ALL of these machines.
Logic sense dictates that I only need to change the template from which the sensors have been created, but in the KB I read disturbing news: changing the template does NOT change settings on the sensors, not even when an auto-discovery is triggered!
I find this highly disturbing, since this IMHO makes a template pretty much useless - why use a template if I can simply clone an existing server and rename that one? Works even faster, since I only have to modify a name and a DNS-name/IP-address... with the same effect.
So how can I now change about 200 memory sensors in a sensible way? I have already tried to use the 'Management' tab at the topmost level and select all the memory sensors, but the trigger values do not appear in the right-hand side.
NOTE: I will enter an RFC (Request for Change) regarding this template issue.
