Who Me Too'd this topic

Hi All,

I've been collecting and plotting CPU, Session, Packets Descriptors, Packets Per Second, as well as some other metrics. Once in a while I see a spike on the Packet Descriptor graph.

According to KB article How to Interpret: show running resource-monitor :

The cores specified in the CPU usage output have dedicated functionalities:

• Core 0: used for Management Plane (MP) and Data Plane (DP) communication
• Core 1: used for session and flow management
• Core 2 and above: used to process network traffic and log processing

Same article talks about: If the output of packet descriptors or buffers stays > 80%, it indicates the device is over loaded and may lead to packet loss and abnormal behavior of the device.

Question: Is there a way to pinpoint WHAT exactly contributes into Packet Descriptor spike? None of the other graphs show anything for the particular period of time. CPU is normal, Session util is fine, Packets per Second are fine for each zone. Is there anything in the logs that I should search for?

Thanks!
