Nothing gets rediscovered at any frequency other than the frequency with which you run discovery.php.

Almost everything collected by the poller is collected by snmpbulkwalk.

It's possible that bulkwalk is failing part way through for this device causing the ifHighSpeed to be set to zero (or set to the value of ifSpeed, which will be just as useless on ports >1Gb)

Hi folks,

we have an alert that triggers when certain ports hit >85% utilisation being triggered by a single device on a regular basis as it seems to get rewalked quite often, which briefly sets the speed of the monitored ports to 0 which then triggers the alert as any utilisation over 0 is >85% :).

The device is a Brocade CES, but it is the only one in our fleet that suffers from this rediscover > trigger alert issue. Though the others also seem to rediscover more often than is necessary.

Any thoughts on how I might figure out what is going on so I can fix it?

Thanks,
Chris
