Is there any way to get ESXi 4 to send an e-mail when volume space gets below x%? I don't see anything like that in the vSphere client, and I don't see it coming up in my searches here although I cannot imagine there are not threads here about it somewhere. How do you guys monitor it?
...you may be able to get this function out of the free Veeam ESX Monitor?
No maybe about it. I installed it, tested it, and it works. That saves me from implementing the ESXi add-on for Zabbix, which would have taken me a lot longer to set up.
