I have been using the vCheck v5 for several months and have nothing but good things to say about it. The script has helped me find and resolve several issues in the environments I maintain. There are a few additional checks that I have come up with myself, but I usually run those manually once a month or so and then view the output from a command prompt. I have spent a couple of hours recently retro-fitting the scripts I use into vCheck format and then adding them to the existing script. If you would like to use these checks, please get the full script from here (after leaving a quick thank-you for Al). Here are my additions:
