As many of you know, I have created a vCheck feature request list (http:\/\/bit.ly\/dGrNjh<\/a>) using comments from the Virtu-Al.net site<\/a>. I’ve been working through them as time permits. <\/p>\n

In a post earlier in the week, I provided a solution to make ‘vCheck as a vSphere Client “Solutions and Application”‘. This post attempted to resolve feature request items #16 and #17. If you are interested, that post is available here: http:\/\/enterpriseadmins.org\/blog\/?p=258<\/a>. It is not really a change to vCheck, but some steps that need to happen to make vCheck appear in vCenter.<\/p>\n

Today, I’m am posting more updates to vCheck. This updated version includes feature requests #2, #11 and #51.<\/p>\n

# Version 5.31- bwuch: Bug fix for LockdownMode\r\n# Version 5.30- bwuch: Add check for VMtools installer connected\r\n# Version 5.29- bwuch: Add check for VM capacity forecasting\r\n# Version 5.28- bwuch: Change to Get-HTMLTable function for possible performance improvements\r\n<\/pre>\n
I’m sure update 5.28 was suggested in the Virtu-Al.net comments, but for some reason I couldn’t find it on the feature request list.  <\/p>\n
Update 5.29 isn’t perfect and I wanted to let everyone know.  There are comments in the code, but I wanted to add them to this post for reference.  Instead of looping through all of the virtual machines and adding up the amount of space used, I simply subtract the data store free space from the capacity and assume that is how much is being used.  We also make the assumption that no more than 85% of a datastores capacity will be used (to reserve room for thin-provisioned growth, snapshots, changed block tracking and log files).  These assumptions make the code run pretty fast, but I’ve seen some oddities in my test environment.  (Like -41 virtual machines remaining in a data center I’m sure has enough free space for 1 or 2 more VMs \ud83d\ude42 )  Here is what I’ve added to the comments of the script for reference:<\/p>\n
# The disk forecast will be per datacenter instead of per cluster since\r\n# Get-Datastore -Entity only supports VirtualMachine, VMHost, and Datacenter objects.\r\n# To improve performance in code, we are going to make the following assumptions\r\n#   Assumption 1.) Disk capacity - Free Space = space used by VMs\r\n#   Assumption 2.) used space \/ count of VMs = Avg Space used per VM\r\n#   Assumption 3.) we will reserve 15% of capacity for overhead<\/pre>\n
If anyone else has a better solution (fast and accurate) please let me know.<\/p>\n
