Configuring Event Statistics

To configure the router to count events on a queue, you configure the threshold above which forwarding or drop events are counted.

A forwarding rate event occurs each time the forwarding rate exceeds the threshold during the specified rate period.

A drop event occurs each time the number of packets dropped exceeds the threshold during the specified rate period.

To gather event statistics:

1. Create the statistics profile.
   host1(config)#statistics-profile statpro-1
2. Set the length of time during which statistics are counted.
   host1(config-statistics-profile)#rate-period 30
   Rate period range is 1–43200 seconds.
3. (Optional) Set the threshold above which forwarding rate events are counted.
   host1(config-statistics-profile)#forwarding-rate-threshold 10000000
   Forwarding rate threshold range is 0–1073741824 bps; default is no threshold.
4. (Optional) Set a threshold for committed (green) packets.
   host1(config-statistics-profile)#committed-drop-threshold 2000000
   Drop rate threshold range is 0–1073741824 bps; default is no threshold.
5. (Optional) Set a threshold for conformed (yellow) packets.
   host1(config-statistics-profile)#conformed-drop-threshold 4000000
   Drop rate threshold range is 0–1073741824 bps; default is no threshold.
6. (Optional) Set a threshold for exceeded (red) packets.
   host1(config-statistics-profile)#exceeded-drop-threshold 6000000
   Drop rate threshold range is 0–1073741824 bps; default is no threshold.
7. Reference the statistics profile in a QoS profile.
   host1(config)#qos-profile qospro-1 host1(config-qos-profile)#ip queue traffic-class tc1 scheduler-profile sp1 statistics-profile statpro-1
8. Attach the QoS profile to the appropriate interface.
   host1(config)#interface gigabitEthernet 1/0 host1(config-subif)#qos-profile qospro-1 host1(config-subif)#exit
9. (Optional) Display the event statistics.
   host1#show egress-queue events interface gigabitEthernet 1/0
