I'm new to esxi/vmware world. Have few question about monitoring esxi host. Now I'm using trial versian esxi 5.1

1. I can see performance charts in vShpere client. Cool. But I want to export this raw data (raw - I mean cvs,txt or some format which I can parse later) to other server to be able to parse this data later and create custom charts. (please do not advise to try vCenter, I need custom charts etc.)

2. I could run esxtop in batch mode and use this data... But... How does vShpere client performance charts work? Where client takes data for charts? So if I will use esxtop batch mode it will add extra load to server. Is it possible to use same source as vSphere client use for charts?

3. There is /var/lib/vmware/hostd/stats/hostAgentStats-20.stats file. Its looks like it is binary format. As I understood it is exactly data which I need?!?! Any ideas how to parse it?

Thanks!

PS: maybe some one know where to find, if there is one, info about processes running on esxi host?
