RE: [ISSForum] EC throttling event rate



With a few exceptions throttling of events occurs when the Database is unable to keep up with the EC.  So generally the best way to improve the EC performance is to improve the DB performance.  However with recent advances in the SP Database there are some cases where a single EC can become bogged down and the Database is fine.  In this case we have not seen a Database be able to outperform two EC's therefore adding a second EC is all that should be needed for performance sake.

SP is limited to 5 EC's, however since the EC is not a limiting factor the need for more than two EC's is usually for other reasons then performance.

Support can assist in determining what is the cause of the throttling of events.

I hope this helps.

Subject: [ISSForum] EC throttling event rate


Good day.

I have constant problem with EC - great number of events such as:
Message     (EventCollector_RSSPSQL) - Started throttling event rate (due
to large backlog of events waiting to be stored in the database).  If this
happens often, this may be an indication that your Event Collector is
overloaded.  [ID=0xc734004c]

Message     (EventCollector_RSSPSQL) - Stopped throttling event rate.
[ID=0xc734004d]

As I understand it is because of very high stream of events. But machine
with EC installed is not seems overloaded, so i'm interesting in:
1. How can I increase EC performance?
2. How can I manage EC queue?
3. How many events per second EC can process?
4. Is it right that SP can support only up to 5 ECs?
.. and others relevant with this problem.

Thank you all!
