Collector event queue has reached it's limit
Hi All
We got this alert today and am looking for some advice on calculating a good figure to increase the limit too, also what if any performance implications are there on the collector ?
Alert: nworks Collector: VC Event Queue has reached its limit

Alert description: VC220 The internal events queue for the nworks Collector has reached its limit. vCenter camvc001 has generated more than the current Collector capacity of 75 events per 30 seconds, therefore some events could be lost. Check for an event storm in vCenter.
This event generated by the nworks collector For more information see http://veeam.com/support/events.aspx?EvtID=119

Re: Collector event queue has reached it's limit
Mark,
You can increase this up to 1000 events / 30 seconds I believe. This will obviously increase the amount of data the nworks Collector will have to query thus increasing CPU utilization. As long as you monitor the usual metrics on each nworks Collector you should be ok.
VM\cpuUsed
OS\Processor Queue
Agent\SendQueueLength
FYI - this is a new feature implemented in nworks MP 5.6, which is why you may have "just" started to see the behavior.
Cheers!

Re: Collector event queue has reached it's limit
I started recieving this alert after upgrading to 5.6. The default is 75 events per 30 seconds, how can I create an override to change this?

I've got the same alert time to time in version 5.6, so I'm also interested to know how to increase this value.mike.bosco@dcsg.com wrote:I started recieving this alert after upgrading to 5.6. The default is 75 events per 30 seconds, how can I create an override to change this?

Re: Collector event queue has reached it's limit
Any chance we can get an answer to this question? I have a very busy VC and tweaking this queue would save me a lot of useless messages.
I could open a support case but since this appears to be a common issue having the solution in a forum would help someone else down the line.
Thanks,
Allen

Re: Collector event queue has reached it's limit
Greetings all,
This new setting (since 5.6) is available in the nworks Enterprise Manager UI. (You cannot use an Ops Mgr override to change this)
Setting is called Event Queue Limit, and you can find it in Advanced Settings in nworks Enterprise Manager, on Enterprise Manager tab when the top node Enterprise Manager is selected.
I would recommend only increasing to around 100 - 150 or so, to see if this stops the alerts. Any increase in the event page size we request from vCenter could have a performance impact on VC.
Note the absolute maximum setting is 1000.
Please note - there are a couple of 'false positives' for this alert (which we will fix in the next update). So do not assume that you need to increase this setting. You can get a false alert if -
(1) the Collector service was stopped for some time. Then the Collector sees the gap in events while it was stopped as 'missed events' and raises this alert.
(2) there is a failover of a monitoring job to an inactive Collector, and this Collector previously monitored the same VC at some time in the past. The Collector sees this gap in monitoring also as a 'gap' in events and raises the alert.
Please see the KB article on the monitor for full explanation of the monitor operation. (Also note, to have the full KB, you should have the latest MP, version 5.6.0.786)
Cheers,
Alec

How do we edit this default value?

Re: Collector event queue has reached it's limit
Hello aperson,
We had similar issues with the VC events limit. (basically due to our busy vCenters)
To increase the limit access the Enterprise Manager, then open the Enterprise Manager tab. Select Enterprise Manager on the left hand column then open the Advanced Settings under Global Collection Settings section. Double click on the Event Queue Limit and set it to your desired value (ours is currently sitting at 350 with no issues). Save your settings. Access your collector servers and restart the nworks Virtual Infrastructure Collectors. Done
I would recommend putting your Veeam infrastructure into maintenance mode whilst you do.
