I'm finally getting my hands dirty on a new vRealize OM setup at my datacenter. One of the main things we need to do is monitor free space on our VMs. Initially, this seemed like an easy task.
I have servers that have many drives on them, and I need to monitor specific GB free on each drive. IE: If any disk gets below 15GB free, alert.
I can't seem to find a metric for this. There's a TOTAL system free GB metric, but that's useless as it combines all drives, so one drive could easily completely fill up and we never get an alert. Then there's a metric for % free of individual drives. But this is useless for us as well we want to monitor a set level of free space, not a percentage which varies too much. Is there really no metric and way to accomplish this? Seems like such a simple thing to monitor for and there's so many similar metrics that there should be a way to do this, but I can't find it. We previously used Veeam ONE and had no issues with doing this.
