Using 2.1-M1, I noticed that DCIs which are set to poll at the default interval are polling every 5 minutes - except our DefaultDCIPollingInterval is configured as 60 seconds.

Originally I assumed this was due to the rather high poller queue, so delays were expected, but after fixing that, the DCI results started coming in exactly every five minutes (as opposed to 5-6 minutes).

Is that some (new?) lower limit on DCI pollers?

EDIT: This is causing some issues for us, as alerts which used to be triggered after 60 threshold violations are now no longer alerting after an hour, but after 5 hours. Changing the DefaultDCIPollingInterval to 120 doesn't seem to have made a difference - all default DCIs are still checking every 5 minutes.

Cheers
