I'm trying to size up a FCP environment where they are running ESX 3.5 directly on the host’s hardware and have some critical non-Windows OS based VMs. There’s around 57 VM’s. 46 are Windows based which I was planning to monitor using the Virtualisation Data Collection Tool (VDCT). The remaining 11 are made up of a mixture of Novell Open Enterprise Server (OSE) and SUSE Linux Enterprise Server (SLES) variants.
Is there a way to monitor these Linux based OS's in a similar way to that of the VDCT? I was thinking of looking into IOSTAT and ESXtop, but i wasn't sure if there's a recommended script to use?
