Looking for a reliable method to monitor Exchange 2010 DAG failover events
Posted on 2013-05-15
I started this same thread on TechNet earlier today but I haven't received the quality of response that I was hoping for, so I'm bringing it to the Experts.
I have 2 Exchange 2010 servers installed on Server 2008 r2. Both have all roles, one is used as the primary server and the second is a passive back up. My question is about how to monitor when a database fails over to my passive server. It seems like there should be an event logged, probably on the server that is taking the active copy since in theory the other one is non responsive for one reason or another. I've dug through the logs and I've found some events that seem to occur around that time, but nothing that definitely says that a failover has occurred. Can anybody point me towards a reliable method of monitoring this?
The suggestions I've received so far mostly centered around how I should get a monitoring system. I do already have a very robust monitoring system, that isn't where I'm stuck. What I need is to find the exact item to have it monitor for this issue. I am aware of a number of different events that can trigger a failover, but I don't think it's a great solution to monitor for all of them. That relies on my having a large list, which is hopefully all inclusive. It would be way more efficient to find an event on the newly active server which says something to the effect of, "I just activated this database."
Is anybody aware of a way to track this? I can't believe that Exchange doesn't log an Event when this takes place, but so far I haven't found it.
Thank you in advance
