I recently had some problems with big queues, is there any way I can get an event to be executed whenever a
queue gets a certain size?
Or do I manually have to check the queue every now and then?
If you take a look at node object representing NetXMS server itself, you'll find some automatically created DCIs. There are queue length for status poller, configuration poller, data collector, and database writer, as well as average time to queue DCI for polling. You can setup thresholds on these parameters as for any other DCI and generate alarms, etc. General rule is that any of this parameters is higher than 0 for long period of time, you have a problem and should do something.
Best regards,

Great, just made policies for them :)
