Hi aLTeReGo,
Here's what they would like to monitor:
ConnectionQueue
ListenSocket http-listener-1
ListenSocket http-listener-1-SSL
KeepAliveInfo
SessionCreationInfo
CacheInfo
Native pools
DNSCacheInfo
Performance Counters
Sessions
and how many connections that currently used.
I think the iplanet proxy is like a squid.
Anyway, I'll try to check also the template you've recommended to me
