ASR 9010 10% increase in CPU usage

Hi Community,

 

Currently I have experienced a sudden increase in CPU usage on my ASR 9010 in past two days. The increase is +10% in all cards (2RSP and 2LC). 

 

Until now there is no problem with any service offered but I wanted to know the cause of this increase and the logs are showing nothing.

Below are the top processes:

JID TIDS Chans FDs Tmrs MEM HH:MM:SS CPU NAME

437 28 88 122 17 3M 21:33:52 0.18% tcp

 

Total usage is 17% -19 %. I understand that it is not high usage but the sudden increase is worrying me.

 

Thanks in advance

Re: ASR 9010 10% increase in CPU usage

The spike seems to indicate a lot of RIB messages were being processed, its possible you were seeing a lot of churn the other day.
