I've just been going through and setting up some monitoring on our esx servers and basically have it all running. Was just wondering if you are able to monitor if:
1. The server is in maintenance mode or not
2. The Licensing status of VMware - License Key, day remaining on license, license details
3. The status of the guests
Can you share what type of monitor sets you have setup to monitor your ESX hosts? At the moment I really just want to get hardware monitoring up and running, so that we're alerted if there is an issue with RAID, or redundant power supplies.
Your best bet for that type of check is the monitor that can be found under Lua scripts:
Monitor/ Script/ Lua Scripts/ wbem_esxi_health_.lua
Performance monitoring is also available, but that script will check the hardware health as you've requested.
