![]() If you want to get only the over provisioned datastore: get-datastore | Get-Datastore2 | Where-Object I wrote the function Get-Datastore2 below to give a clear output of the state of the datastore without having to dig into the objects. There are plenty of good and free tools that will do the job like RVTools which is a must have! But it is more interesting to do some PowerCLI to get there yourself. Now you probably want to know which one of your datastores are overprovisioned. PowerCLI script to find out the overallocated datastores That’s all, you will now get alerts on overcommitment threshold. You could also set the critical alert to repeat every X minutes, I like it to be annoying so we take the time to deal with it. You can then configure the action according to your alerting process (email, snmp and so on). The default thresholds are Warning = Datastore 100% Provisioned and Critical = Datastore 200% Provisioned.īut because I am a little bit paranoid and I don’t use thin disks a lot I set a lower value to be warned when 130% is reached. Then add a trigger, and select “Datastore Disk Provisioned”. To set it, select your vCenter on the “Manage” tab then “Alarm definitions” and select “Datastore usage on disk” This alert isn’t set by default and is “hidden” in the datastore usage alert. See this very good post by Cormac Hogan for more details: Thin Provisioning – What’s The Scoop? Add an alarm for datastore overcommitment The thin provisionned VMs asking for extra storage will be paused (imagine the db of a web stack).The thick provisionned VMs will keep running as the space has been “reserved” on the datastore so it is already ready for usage by the VM which is good.However, if you get to the point where one of your overcommited datastore runs out of storage you might get into trouble. no surprises with tempdb filling up) it is sensible to have a bit of overcommitment environment. If the storage is well monitored and the storage activity of your VMs is predictable (i.e. Since the dawn of times in virtualization it is possible to thin provision the disks of the virtual machines by not allocating the blocks to it, hence over commit the actual physical storage by provisioning X+Y GB even if the storage has only X GB to offer.
