[Observium] Ports Shown As Down

Hi,

After a power outage, the front page (and Status Warnings and Notifications) is showing a Cisco device's Ports as Down, of all ports that have NO devices (workstations) connected.

The alert I have defined (taken from the example)

Port is enabled, but operationally down ifAdminStatus equals up ifOperStatus notequals up * ifType equals ethernetCsmacd

I have run the poller.php multiple times with no success.

Is there a default amount of time until these warnings will be cleared, is there a process that can be run to clear these alerts?

Thanks Laurence
