Can you screenshot the Performance Data of that device? Cog-wheel at the top right on the device-page.

Cisco Nexus have a pretty bad SNMP-stack.

I did a manual discover (Discovery time - 206.3) but it still marked as deleted:

2017-12-12 14:42:05 Interface was marked as DELETED < after my discover.

2017-12-12 14:26:32 Interface DELETED mark removed

2017-12-12 14:22:16 Interface was marked as DELETED

2017-12-12 14:06:33 Interface DELETED mark removed

2017-12-12 14:01:56 Interface was marked as DELETED

2017-12-12 09:56:36 Interface changed: [ifAlias] '' -> 'vPC Keep-alive link'

What's wrong ?

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 ? :)
