PA CPU usage via the API

Mohammad.Qawasmeh — Tue, 30 Apr 2019 14:18:29 GMT

Hello All,

In PA Firewall Dashboard we have the system Reousrces widget, were we can see the Management CPU and Data Plane CPU usage, I was trying to do the same using the API, but I'm not sure how PA are calculating the values,

The GUI is sending a POST request to the backed PHP code (DashboardDirect.getSystemResources) to get the values.

But we don't have such API available to use,

So for DP CPU usage we can use *show running resource-monitor* API and we can calculate the CPU load during the last 60 seconds and we can get a value that is similar to the one in the GUI.

But for the MP it's a bit complicated! *show system resources* API will return a text output of the command itself, and we can get the details from the below part
*Cpu(s): 51.9%us, 5.4%sy, 1.0%ni, 41.6%id, 0.1%wa, 0.0%hi, 0.0%si, 0.0%st*

So my concern is how to calcluate the load average from the output, and I'm trying to query the api multiple times but I'm getting the same output each time for a long time!! the below row will never change! any caching is being done via the API ?!

*Cpu(s): 51.9%us, 5.4%sy, 1.0%ni, 41.6%id, 0.1%wa, 0.0%hi, 0.0%si, 0.0%st*

Thanks!

Mohammad

You could also just query the mp-monitor.log from the API which is going to return in the same format you saw in show running resource-monitor

3 year bump here, trying to achieve the same and noticing the same that it's a backend PHP code call.

You can also get the same info via >show system state | match sys.monitor.s0.mp.exports, unfortunately it returns a non-XML formatted response with a huge amount of text. (credit: https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000PLKKCA4)
