[Observium] Best practice for alert threshold per devices

%Hello,

I’m trying to define different alert threshold per devices.

I’ve tried by proceeding like this :

1° I’ve defined a global alarm for all my devices having disk over 90%

I’m associating this alert checks to every devices except those in a specific group

2° The group with id 17, correspond to devices for which I accept a disk filled under 95%

3° I’ve defined a second alert check specifically for this

Is it the good way to achieve my goal ? Is my syntax correct ?

Best Regards

Thibault
