Add maintenance window to supress alerts

[MorganMLGman]

Hi,

I think it would be beneficial to add something like maintenance window or maintenance switch that will temporarily disable sending alerts when triggers are activated.

Maintenance window with start_date_time and end_date_time would be better than switch as switch could be forgotten and left on.

This should be possible to set per machine or global. Stats should still be collected, but any alarm triggers will be suppressed during maintenance.

I came here to request this feature. Right now I have to manually pause each machine monitor. Luckily all I have is 5 machines but it's still annoying. It would also be nice if you didn't have to set a time but just an activate maintenance mode button or pause all machines that then needs to be manually turned off.

I'll try to get an option added for this in the next feature release or two.
