We use a combination of Dell Open Manage and IT Assistant to monitor SNMP traps for our Windows Servers. We have just recently setup a 3 server Hyper-V 2012 failover-cluster and all appears to be working fine. However on one host, and on the cluster IP, we are getting notifications every 30-60 minutes (and while it isn't every 30 or 60 minutes, it is in exactly 30 or 60 minute intervals) from IT Assistant as follows:
Device:[devicename] 
, Service Tag:
, Asset Tag:[AT], Date:04/08/13, Time:07:25:38:000, Severity:Warning, Message:A HyperV Host has been modified
Obviously bracketed items have been masked since it shows our info. We do not have any scheduled jobs running on these servers and at this time only have 5 VMs attached to the cluster which are not doing much right now, so we cannot track down what would be modified on the host on such consistent intervals . Anyone have any info on how, what, when, and why Hyper-V would send out SNMP messages?
