Dataplane under severe load

I got this message on the dashboard of my PA - "Dataplane under severe load"

This is the result of the setting "Enable Log on High DP Load" which can be found from Device -> Setup -> Management -> Logging and Reporting Settings. When this option is toggled on, a log will be created whenever the dataplane reaches 100% CPU.

Sometimes the dataplane spiking to 100% CPU usage can be fine and in most cases, traffic flow won't be affected depending on the utilisation of the packet descriptors (on chip) or packet buffers. You can check these with the command "debug dataplane pool statistics". However, it's always a recommended best practice to keep your PAN-OS up to date in alignment with recommended releases to make use of bug fixes that may impact dataplane CPU usage - as I'm sure you're aware 🙂

Cheers,

Luke.

@LukeBullimore

Yes I do have the feature enabled and I checked and the CPU wasn't at a high level when I checked it so what is the benefit of this alert?

Hello,

It basically tells you that the CPU was at that level. Unless you have a 3rd party tool to monitor things such as CPU, memory, diskspace, etc., it really wont show a trend unless you are getting a lot of alerts frequently.
