Cisco Port Channel Monitoring

To add to this -- there is in fact a pair of datapoints in the new SNMP_Network_Interfaces datasource that could be used to detect aggregate speed problems, a proxy for channel member loss (inInterfaceSpeed and outInterfaceSpeed, set to the reported speed unless overridden by ILPs).  To use this, you would either have to set a threshold on the specific datapoints needed and deal with generic alerts, or add a virtual datapoint with a proper alert message, making future module updates painful.  I really wish that the F/R I posted years ago to allow for LogicModule inheritance was implemented...

If you use SNMP_Network_Interfaces in any real world environments, be sure your collectors have been tuned to allow more batchscript threads!
