Security

Hi

I am having slowdown on the clearpass GUI and high CPU warnings periodically.  Running as 2x 5K version on a cluster on windows Hyper V.  Clicking on an access tracker entry can sometimes take a few minutes.

Whereas it used to be quite fast although there is a lot more activity on our network now.

How can I start to work out what is the cause and how to resolve it?

I set them up with the resources the Hyper V document stated.

Thanks for any help

Been looking into it, in more detail.  

It seems not to be CPU usage but High I/O wait when accessing the GUI and data in the database:

CPPM[clp02] System(CPU): High I/O wait(10 min avg) - 18

The CPU usage isn't high.

Please open a TAC case on this subject.

High IO wait, typically means that your disks are too slow (not enough IOPS), which can be that the hypervisor infrastructure is overloaded, or you have not enough physical disks in a RAID, or the wrong RAID configuration.

Thanks. I will look into it.  It is using RAID 1+0 on four SAS disks with a 10/90 read write cache config.

the second node with the same setup does not slow down.

Did you ever resolve this? Same thing is happening to me after upgrading to 6.7. TAC has NOT been helpful at all...

 Ryan,

Have you escalated this case you had at TAC?

Can you send me a personal message with the case numbers, so I can have a look at it?

in my case, I moved all the authentications on to the subscriber and left the publisher just mostly doing publisher role.

This enabled the web gui to be responsive.

The subscriber copes with the authentications as well
