Hello,
i have a serious problem with Alerting system.
For example, if i create a test rule (see image)
IF LibreNMS find a machine with hostname equals to “pensiero” ( and i have a machine with this name ) the alerting system will be triggered, right?
And it is so, i receive the first Altert after 8 Minutes ( not 5m )
After this, I should receive the same alert every 10 minutes - infinite times (-1), until status change, right?.
but it does not happen, why?
(i receive only the first CRITICAL alert but nothing more after that)
Please help me to troubleshoot that
Thank you very much
