Description
How to check whether the licensed throughput limit is reached and where the heavy traffic comes from
Instructions
- If licenses throughput is 500Mbps, then we can extract the real time throughput over 500 from newnslog.
- To enter ADC's shell mode, type "shell" and then type "cd /var/nslog" to enter nslog directory and then issue the following commands, here we can see that the real time throughput is indeed over 500 sometimes . At the same time, we can see that the heavy traffic is received on interface 0/2.
# nsconmsg -K newnslog -g mbits -d past -s disptime=1 -s ratecount=500 | more

- We can also check whether there are packets dropped due to licensed throughput being reached.
