Subject:        [TME10] Correlated situation overhead on ITM HTEMS
Sent by:        [email protected]



Hi List.
 
A question came up recently about the growing number of ITM Correlated 
Situations running in our environ. These SITs run on the HTEMS, and we?d 
like to know if they consume a significant amount of HTEMS resources, and 
if so, what is a reasonable number to have running? Currently we have 
about 2 dozen correlated SITS.
 
I would think that since correlated SITs are based on a comparison of 
true/false values from other SITs, that the HTEMS is probably not sifting 
thru much data and could handle a pretty good number of these.  We have a 
pretty healthy 24-CPU, 16GB mem Sparc Solaris HTEMS, with a load avg that 
rarely goes above 2, and about 6400 OS agents in the environ (ITM 622, 
FP5).
 
Any experiences running a large number of correlated SITs?
 
Thanks in advance,
 
-James
