Hi, we have a Cisco C7200P router at work running IOS 12.4(12.2r)T, and we monitor it using Zenoss 3.1. We want to be able to capture the total output drops for a Gigabit Ethernet interface. I created a custom monitoring template and I added the following data source:
The total output drops as viewed via the CLI are as follows:
Input queue: 0/75/1335749/399902 (size/max/drops/flushes); Total output drops: 53882894
However the graph on Zenoss reports a completely different value of ~360M. Here is the output of snmpwalk:
Did you tried using ifOutDiscards (.126.96.36.199.188.8.131.52.1.19). These are counted as output drops as shown in the show interfaces command.
It shows the number of outbound packets which were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a packet could be to free up buffer space.
