Good morning,
Firstly, a little background. We are in the process of setting up a new DC and currently have about 15 assets configured in Check_MK. My windows colleague is configuring a BackupExec server, and for the duration of the config, I would like to postpone monitoring (to save getting hundreds of unnecessary notifications).
I must also point out that once this monitoring is set up, we will be handing it over to staff who have no Unix experience (or indeed any SSH access to our servers), therefore I have been tasked to ensure that EVERYTHING is setup in the GUI rather than editing the files (main.mk etc.) directly.
Therefore, I went in to Hosts and Service parameters → Monitoring Configuration → Hosts to be monitored → Create rule in folder (Windows).
I then entered the name of our BackupExec server in the Explicit Hosts section, and chose the Negate option. From my understanding, this would tell Check_MK to monitoring everything BUT that server (exactly what I want).
However, the effect was that all my assets dropped off the monitoring tool! I played around with the various logic options (got rid of the negate and made the ruleset negative instead), but got the same effect.
I’ve ensured that the server name I entered exactly matched (including domain suffix), but to be honest, even if this was incorrect I still wouldn’t expect for all my hosts and services to vanish from the monitoring!
I’ve solved the problem for now by going in to the individual services for the host and unchecking the ones that my colleague is working on, but I would really like to know why this other option did not work.
I hope that makes sense. Please ask for any further information as needed.
Also, thank you very much in advance for any help.
Regards,
Pete
