Saw an ad for VMTurbo, which promised monitoring for Virtual Machines in an environment. I missed the fine print that indicated that it required vCenter, so it doesn’t work on ESXi.
“Free VM Monitoring” is prominently displayed on the front page. “Doesn’t work with ESXi” is on a forum post that requires a Google search.
If I’m spending money on the virtual environment I’m building, I’m spending it on Veeam.
