IHAC asking what would be the "top 10" items to monitor for in ops manager when using v-series in a thin provisioned envirnemnt.
I can come up with the first few pretty easily - but wonder if we havea nything offical around best practices for monitoring and alerting?

If you are looking around thin-provisioning, Operations Manager has some good monitoring and reporting mechanism. The thing about thin provisioning is customers always to keep an eye on this "overcommitment" attribute to ensure they don't run out of control - We have a custom report which provides a preety good overview of real capacity utilization vs overcommitment. You get to understand the reailty of capacity utilization on your aggregate (by calcualing the daily growth rate, used capacity, space saings if any). (screenshot 1)
You also have the capability to set thresholds on over commitment and configure email/pager based notifications (screenshot 2)
Plus, we have over-commit vs capacity utilization historical chart which can trended upto an year (screenshot 3)
Thanks and regards
