One of the most useful scripts for ESX in my opinion is health_check.sh. This scripts generates an html file which contains a enormous amount of useful info on how the ESX host was installed. Besides that it contains 30 lines of the most important log files and for instance if there are snapshots and much much more. I just tested the script on ESX 3.5 and it still works great. The script is created by two guys of the Danish VMUG one of them is A. Mikkelsen, check his blog for more scripts! Be sure to check out this script, it’s worth it! By the way, you can schedule it and have the html emailed to you via the use of smtp_send.pl.
