I am looking for more detailed qos statistics on the Nexus switches.
Here is what I have found: "qos statistics" used to enable statistics, this is enabled by default. What I don't find is the display of any detailed statistics showing total packets matched in each queue. Is this information available somewhere and I simply am not using the correct command to display?
"show interface ex/y" shows the normal input and output
"show policy-map interface ex/y" shows:
Service-policy (queuing) input: default-4q-8e-in-policy
Class-map (queuing): 2q4t-8e-in-q1 (match-any)
queue-limit percent 10
bandwidth percent 50
queue dropped pkts : 3883
Class-map (queuing): 2q4t-8e-in-q-default (match-any)
queue-limit percent 90
bandwidth percent 50
queue dropped pkts : 16194
Service-policy (queuing) output: default-4q-8e-out-policy
Class-map (queuing): 1p3q1t-8e-out-pq1 (match-any)
priority level 1
queue dropped pkts : 158844
Class-map (queuing): 1p3q1t-8e-out-q2 (match-any)
bandwidth remaining percent 33
queue dropped pkts : 0
Class-map (queuing): 1p3q1t-8e-out-q3 (match-any)
bandwidth remaining percent 33
queue dropped pkts : 0
Class-map (queuing): 1p3q1t-8e-out-q-default (match-any)
bandwidth remaining percent 33
queue dropped pkts : 856611
It is good to know that some packets are being dropped, but out of how many total packets? Is the drop percentage 50% or 1%, if i want to change the policy it would be good information have as to how many packets are being matched in each queue. What am I missing?
"show queuing interface ex/y" shows:

Nothing that I didn't already discover from the show policy-map command.
Thanks for any information you can provide.
