proc files explanations

[Manuel Arostegui Ramirez]

Hi all.
I'm trying to keep LVS monitorized by using Pandora Free Monitoring system
and I have to deal with the LVS' /proc files, so I'd like to know if there's
any document where fields and meanings of the files below is explained. I've
already found out some obvius fields of that files, but not all. I suppose
there's something out there but I found nothing, though.
These are the files, by the way:
/proc/net/ip_vs
/proc/net/ip_vs_app
/proc/net/ip_vs_conn
/proc/net/ip_vs_stats

Any suggestion will be really apreciated.
Thanks in advance.

Manuel.
