Hello
I’ve something strange with a basic alert checker
I’ve defined a basic alert-checker to check if my devices are down

The test condition is device_status equals 0
I know it works because I already had some working case.
I’m astonished because I have a case with devices shown as down :

… but not reported by the alarm-checks
The device is a | Dell EqualLogic PS4210 |

Do you know what my mistake could be ?
Best Regards
Thibault
