This subject is always interesting - servers running out of disk space. For a couple of weeks my collegue and I have been looking for at way to trigger an event in Virtual Center when one of the dearly beloved virtual machines runs low on free space.
This mail thread seems to show that this is not possible through Virtual Center - at least not in december 2010.
Now were running 5.0 so the question is if anything has changed here? Could it be that a new event has arrived saying "fireTriggerWhenVMisAbove80percent" so we can see it in Virtual Center as well as send a trap to HPO ?
We're looking at this from two different angles:
1) Fire an event (hopefully an snmp trap) when free space falls below an absolute value (say: 1 Gb)
2) Fire an event (again, in best case an snmp trap) when space falls below a relative value (say: 80%)
