OK here is a quick few off the top of my head, Alan has mentioned a large number that are annoying. A lot of mine come from the consultant side rather than just day to day administration. I understand their are a lot of powershell scripts out there that could do a lot of what im asking, its just trying to find the time to improve my powershell skills enough to be confident with what im running and customising to my skill level.

As a consultant I maybe visit some of our customer only once or twice a year to add one new host or do some upgrades etc I need to compare all the key configuration settings across all hosts in a cluster, such as Service Console Memory, vSwitch names and number of uplinks, NTP is enabled and configured the same, DNS and Default Gateway is configured the same and all those other little settings you want to check are configured the same on all the hosts. << Would be lovely in a single report.

Working out what had changed in an enviorment that was working fine when you installed it. After leaving a working system with a customer and the customer then tweaking it and causing an issue. Would be nice to be able to run a report at the end of the project then run a report on the next visit that could tell you what had changed since the last report.

Health checks and documentation, theVESI has helped immensely with both of these but it still involves me running each report manually and then copying the data into word. This really isn't much of a hardship, but when trying to standardise documentation and healthchecks across multiple engineers it would be nice to be able to have some kind of report builder where you could select which VESI functions to run and then be able to export these as a settings file to give to all our engineers.
