PowerCLI Script to Check Host Over-commitment Percentage & Ratios

At my previous employer, we had a Dev/QA vSphere environment that was very over provisioned.  The environment had lots of CPUReady issues with VMs having to wait for CPU time, which caused things to be slow, etc.  We knew this but the application teams didn’t understand.  I ended up writing a PowerCLI script to check the CPU overcommitment and sent the results to my manager who was able to go to the application team’s management and get them to clean

Script to backup your vCenter DRS Rules

I was thinking yesterday, I have a script that I run on a monthly basis to backup my vDS configs…  Shouldn’t I also have something that does the same for my DRS rules?  So, I wrote a script that I can schedule to run on a weekly/monthly basis to backup my DRS rules. I have multiple vCenter servers, so I used an array to connect to each one and then exported the rules for each cluster within those vCenters. The

PowerCLI Script to create new vDS Portgroups

We deployed new hosts into one of our office locations.  Because these hosts would have different number of uplinks as well as use a LAG group instead of normal dvUplinks, we decided to create a new vDS Switch.  Then, we needed to re-create all the portgroups as well.  I figured, instead of manually adding 15-20 portgroups, I’ll automate it.  I used this blog post as reference to do some of the work, and added the LAG and uplink changes.

Creating shortcuts for PowerCLI that automatically log you in.

I recommend you upgrade to the latest version of PowerCLI (6.5.1) for

Script to delete folder older than 30 days… by Name

I had a need, on one of my file servers, to delete some data that was older than 30 days, to clear space.  This would need to be a re-occurring task, so what better way to accomplish it than to script it! Here’s the rub…  The folders are each in a YYYYMMDD format (ex: 20170115), yet the content in the folders could be dated other than the folder name itself.  For instance, there could be a folder (say 20170626) that
