Hi all,

How can I monitor memory statistics on dataplane from the CLI (not SNMP) ??

Regards,

@licenselu,

'show system resources' will show the total, used, and free memory stats right at the top of the response.

Hey @BPry

Correct me if I am wrong but isn't show system resources to view management plane related processes?

For viewing dataplane health I would use the "show system resources follow" command. For historic logs you would then use the "dp-monitor" log (> less dp-log dp-monitor.log)

Hello,

The less mp-log dp-monitor.log command generates a massive output values !!

Which counter indique the memory used on the DP ?

PS: In fact, show system resources gives the mem on the MP...

Hey @licenselu

In the output from the dp-monitor, you'd want to start reading from "malloc allocator".

If you have access to PANTS or AutoAssistant tools then you can drop a tech support file in there and generate some cool graphs based on DP MEM utilisation as an aggregate or a per process basis.

@LukeBullimore,

Definitely right. The whole reading thing before second coffee is real hard 😉

@LukeBullimoreHey - are you a PA customer? Did your SE get you access to PANTS ot AutoAssistant? If so, on-prem or hosted?

Hey @dberber1

I'm a partner, Technical Partner of the year 😉

Pants is available to ASC Partners

https://asctraps.paloaltonetworks.com

AutoAssistant I believe is available only for CPSP partners

https://autoassistant.paloaltonetworks.com

In which case, your best option at the moment would be to create some graphs in excel based on the data from the dp-monitor.log. This log file is contained in a tech support file or otherwise you can obtain it via SCP:

> scp export log-file data-plane
+ remote-port SSH port number on remote host
+ source-ip Set source address to specified interface address
* to Destination (username@host:path)

Otherwise, reach out to your SE.

Cheers,

Luke
