Did anyone else experienced similar issue?
I have an active alert on device port that is admin up oper down because i’m waiting for customer to connect its equipment.
Somehow after 3 days librenms decides to resolve the alert and activate it again after 5 min (polling interval). I’v checked device logs and there was no change to port state
Hi @Dejan
One possible explanation : an issue during poll (missed poll, incomplete poll) which would end up as port being wrongly “seen” admin down.
And if port goes “admin down”, alert is cleared (that’s expected). And of course at the very next successful poll, alert comes back as the port is seen admin up again.
Try to check if you have connectivity issues between libreNMS and your device, timeout issues during SNMP polls (which you can sometimes solve with longer timeout in LibreNMS snmp config), etc etc.
Usually, if this kind of issue happens, you also see some spikes on graphs for ports that are oper-up and carrying traffic.
