Hi,
customer has got Exchange 2010 SP1 environment - 8 servers in DAG, 6 servers as CAS/HUB plus two servers with EDGE role installed and some additional servers. Environment is monitored by SCOM and SCOM has got some collecting rule described here: http://technet.microsoft.com/en-us/library/ff360216%28EXCHG.140%29.aspx
Counters from node MSExchangeIS Client are present only on servers with MBX role and from these servers collecting rule tries to collect, but all of these counters has value of 0 (zero).
In Exchange 2010 all connections from client are terminated at CAS servers, but on CAS servers counters from "MSExchangeIS Client" are missing. It's expected and counters for MSExchangeIS Client on MBX servers must be activated (they are enabled) or these
counters are useless on Exchange 2010 mailbox server?
