I am seeing more and more the following happening in our environment:
Log entries appear in this order:
1. VMs show as disconnecting in the logs
2. host shows as not responding
3. Cannot synchronize host - this is a default alert, yet doesn't show up as triggered in the "triggered alarms"
4. Host connection failure triggered by event 887153 - this is a default alert, yet doesn't show up as triggered in the "triggered alarms" ; and someone please help me with the event ID 887153, can't find info on it anywhere...
5. Host connection failure triggered an action
6. Host connection failure sends snmp trap
Then, 40 minutes later... (sometime only seconds later, sometimes minutes, but in this specific case 40 minutes, but it varies without rhyme or reason)
7. VMs start to connect
8. Established a connection (obviously this refers to the host but this is all you see in the entry)
and that's it...
SO, where is the red to green snmp trap?? or yellow to green you should see described in VMware Knowledge Base ???
the alert by default is supposed to send an snmp trap when the alert changes to green, but nowhere in the logs is this showing that it turns Green. therefore, no trap is being sent to clear the condition to our monitoring system.. and the alerts aren't showing up as triggered, so they aren't being cleared automatically.
I want to know what the underlying cause of these alerts, so it can stop. Also, the references to these alerts being triggered when coming out of standby mode is irrelevant, we don't use standby mode, it has nothing to do with it.
I wonder though, perhaps this is because our blades are in a balanced power mode and not static high performance??? thoughts?
