Exchange Slow FindRow Rate

Just looking for some feedback from other admins who have run across this issue(?) with the Slow Findrow Rate threshold for Exchange 2010. WUG is frequently throwing out messages saying that the Exchange server is down, and the popup on the message mentions that "Slow Find Row Rate is ## which is NOT less than the threshold value of ##FAILED". While I understand what the message means, what's a good way to track down the cause on the Exchange server?

Thanks

If it is any help, here is the Microsoft documentation we used for setting the default values for the performance metrics: http://technet.microsoft.com/en-us/library/bb201720(EXCHG.80).aspx.  Once there, go to the "Monitoring Mailbox Servers" link.  This particular counter is in the Client-Related Search Counters section.  This is what Microsoft has to say:

"Should be no more than 10 for any specific mailbox store.

Higher values indicate applications are crawling or searching mailboxes, which is affecting server performance. These include desktop search engines, customer relationship management (CRM), or other third-party applications."

I had looked at the documentation at this link. All I could find here was recommended thresholds for certain performance indicators. As we have not done much but use the default values for these parameters, my next (current) task is finding out WHY we're going over. Not sure where to start on finding the application(s) that are causing the errors.

So, one thing you could do is use Flow Monitor and Flow Publisher.  You could install Flow Publisher on the mail server, and configure it to publish data to the the Flow Monitor instance.  This would give you visibility into all of the traffic going in and out of the Exchange machine.  This would allow you to pin point who is communicating with Exchange the most.

Another thought that came to mind after reading the counter description a few times, was to look at the message in WUG as to why it failed.  Based on the counter description, I would think that it would list the mailboxes that were above.  If that is true, then you could start with one of the offenders and start looking at what applications are installed on that machine.

My knowledge of Exchange is very limited.  Any Exchange guru's have any advice?

Not surew whre to help you find what is causign this I did find this on Technet not sure if it will help though, http://technet.microsoft.com/en-us/library/ff367871.aspx under client-Related search Queuing counters. 

Slow Findrow Rate

Shows the rate at which the slower FindRow needs to be used in the mailbox store. Should be no more than 10 for any specific mailbox store.

Higher values indicate applications are crawling or searching mailboxes, which is affecting server performance. These include desktop search engines, customer relationship management (CRM), or other third-party applications
