vCheck is a tool developed by Alan http://www.virtu-al.net/ owner. vCheck is a stet of PowerCLI scripts which checks your system against deviations from standard configuration and gives nice HTML report :-). It is fully configurable, you can specify for example, ReadyTime, disk latency, snapshot thresholds etc.

First, download vCheck from Alan site http://www.virtu-al.net/featured-scripts/vcheck/ – I assume that PowerCLI is already installed. Unpack it. Next thing to do is run Setup wizard.
.\vCheck.ps1 –config
vCheck wizard
Provide all information
At the end of config wizard, script runs (depends on environment size) between 15 – 40 minutes or so and depends what you set, either send you an email or open HTML report in local browser or both. Below part of the report (Capacity planning) from vCheck

I really recommend to look closer on that tool. It gives human readable and cohesive report 🙂 (which is not always the case) with all information which admin needs, to have global overview over its kingdom 🙂 and it’s free.
