Internet response times spike from average

Hi All

I was hoping that someone maybe able to help with an issue I am seeing, periodically we see the Internet response time is around 2000+ ms from an average of 20 ms. Looking at the logs this is all I see.

Does anyone have any ideas of the issue, the sensor verion 7.0(7)E4.

Hi,

Though the messages look normal, sensor is using high amount of memory.

Is there a particular signature which is firing a lot ? Do you have latest signature set ?

Hi Sawan

Thanks for the update, do you know whats the best way to see if a particular signature is firing a lot.

Regards MJ

Yes.

Use the following CLI:

sh statistics virtual-sensor | be SigEvent count

You should get the output as following example:

Per-Signature SigEvent count since reset

             Sig XXXX.Y = n

             Sig ABCD.E = m

Hi

I have attached the outputs, if you are able to help this would be much appreciated.

Regards MJ

How much is the exact Memory Usage and Processing load on sensor ?

Use CLI "show statistics virtual-sensor"

Sawan Gupta

Thanks & Regards, Sawan Gupta

Hi Sawan

Sorry have been delayed in my response.... Hopefully you will still have time to assist...

Regards MJ

The processing load and other stats look normal. You may want to open case with Cisco TAC.
