High Management Plane CPU

Frazão — Thu, 23 Feb 2017 14:29:12 GMT

Hello, good morning

I am experiencing a High Management CPU situation (PAN OS 7.1.7)

What is this mongod process?

How to solve this problem?

Thanks

Hi,

The mongod process is the Mongo database used for the correlation engine, if I remember correctly. How long has it been using high CPU time? Did it happen after a reboot?

@BenjAudy.MTL is correct. It would probably be advised to request support form TAC in this type of situation where you have already pin-pointed the cause of the CPU spike. If you have just restarted the device then seeing a slightly higher mongod utilization wouldn't be out of the ordinary

Potentially you may be able to fix it by issuing a debug software restart process device-server and a debug software restart process management-server. Since this doesn't effect the dataplane your traffic will still be forwarded and users shouldn't notice a difference. I'm not positive this would actually restart mongod though, so if this doesn't work I would try scheduling a restart of the whole device.

It happened suddenly
Even after rebooting, the problem persists

It could be corrupt, which would explain why it's running so high since it would be trying to process something that it cann't. I would contact TAC and see what they can do for you.
