Hi,

Alert (and group) associations are rebuilt directly after a device discovery, so if during a discovery some ports are removed or their ifType/ifAlias is returned black because of timed out snmp, they'll drop off this checker.

Do you see the ifType/Alias being changed in the entity's logs?

Hello,

I've created alarm checker:

os equals nxos
hostname match *NET*

ifType equals ethernetCsmacd
ifAlias match *vPC Keep-alive link*

And after a while i noticed that some entities where disapeared. The device was reachable and etc.
I did a "rebuild' and they're reappeared again. What could be the cause ? NXOS ? :)
