Hey @alankoh,

Is the snapshot size on the Snapshot Management console showing as more than 1Gb?

hi lalegre

sesparse is more then 1G but snapshot doesn't reflect in vcenter

ls -lrth *.vmdk

@alankoh,

What if you try to increase the size even more and apply the alarm at the Virtual Machine level instead to the cluster, just for the purpose of testing.

Hi Lalegre

It seems that the only way is to create another snapshot on top of the current - the alarm will then trigger which seems wierd because the 1st snapshot has already exceeded 1GB

In the GUI, it seems like the 2nd snapshot is reflecting the size of the 1st snapshot ...
