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'

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

top - 07:28:36 up 2 days, 22:13, 2 users, load average: 0.11, 0.07, 0.02

Tasks: 93 total, 1 running, 92 sleeping, 0 stopped, 0 zombie

Cpu(s): 2.3%us, 1.2%sy, 2.5%ni, 93.5%id, 0.3%wa, 0.0%hi, 0.2%si, 0.0%st

Mem: 1007852k total, 793756k used, 214096k free, 25092k buffers

Swap: 2008084k total, 775748k used, 1232336k free, 228728k cached

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