About monitoring Memory statistics for DP and MP

[ttongfly]

Hi Guys.

I want to know command on CLI or WEB-UI for monitoring memory statistics for Data Plane and Control Plane in realtime.

It's important for POC and BMT.

Thanks.

Regards.

Roh.

To monitor the control plane:  'show system resources' or 'show system resources follow'

To monitor the data plane: 'show running resource-monitor' will show you CPU and buffer utilization on the DP. Or you could tail the dp-monitor.log 'tail follow yes dp-monitor.log'

Thanks a lot

But I want to know that memory statistics of DP and MP and I could only find cpu info from what you suggested.

Thanks.

You will see the memory utilization if you give the output of those commands another look.

Look for this in the dp-monitor.log:

Jun 07 20:03:51:  --- memory

Last 180 seconds

Type       Free (kB)     min (kB)      Total (kB)

Mem        7564          7548          254468

Swap       0             0             UNKNOWN

Or in the output of show system resources

Note that the DP does not have any swap, but the MP does.
