Hi guys. I have some questions:
Do you have a best practices for interfaces errors in/out, discards in/out threhsolds ?
Does there a way to measure this using percent of packets per second through the interface ?
Does there a list of metric description of snmpcollector ?
No, the only type of best practices doc is on how to configure the probe:
snmpcollector probe - performance tuning and optim - CA Knowledge
As far as best practice for setting up what to monitor and thresholds that's up to you to decide based on what the device is doing and its importance.
Basically the probe will collect data for whatever the device supplies. See the device support site, referenced below, to see if it has the % item you are looking for.
UIM SNMP Device Support
There is UTILIZATION metric in snmpcollector probe. The unit is percent and the metric can be collected per interface.
