BPX processor and statistics

I would like to build my knowledge on BPX processor utilisation and statistic collection.

How do they relate, how can you confirm which statistics have been enable and what is the individual weighting in terms of processing and storage for each or all statistics enabled. I.e. is there a way of identifying the statistical memory usage?

The aim I have is to increase the processor idle average from a low 50.

Thanks,

DK.

Re: BPX processor and statistics

Use the following commands to establish baselines:

1. dspprf (displays cpu utilization of system resources)

2. dsptrks (displays trunk count)

3. dsplns (displays line count)

4. dvc t (displays connection count)

Re: BPX processor and statistics

To add to the previous reply, I am not aware of any specific command that will tell you the info you are looking for. As the other reply suggests, its not only the type of statictic that is enabled, but the amount of objects for that stat that weighs on the CPU. i.e. if you have collects stats on connections, then a BPX with 20 cons will not be affected as much as a BPX with 2000 cons.

The best thing to do would be trial and error. Enable stats and watch the output of the DSPPRF/DSPPRFHIST commands.

Re: BPX processor and statistics

In addition to the mentioned commands and possible actions there are two Technical Tips about recovering real time in WAN Switches:

http://www.cisco.com/warp/public/74/76.html

Be aware that the second one was written for the IGX, but it gives some hints on BPX as well. Generally I would suggest to identify the dominant processes with dspprf or dspprfhist first and then see, what can be done.

kind regards

Martin
