I remember eons ago when I was running Patrol training in Oz for BMC
that it averaged something like about 5% or so.  Depended on how many
things you were monitoring and what the levels were set at IIRC.  But
that's quite dated now so I'd respect others figures more.

We are in the process of implementing BMC Patrol for
monitoring our databases.  This is a good thing since
we have hundreds of database across several states. 
Monitoring from a single location with one tool makes
sense.

However, the question has arisen about the actual load
that Patrol will put on the databases.  To read
Patrol's data, there are words such as, 'negligible'
or 'minimal' but they offer no solid metrics.  In the
not too distant past, BMC's Perform and Predict
product literally consumed all of the memory on our
database machines and ground them to a halt.  It took
several weeks before BMC was able to correctly
diagnose the problem and come up with a fix.  Rather
than repeat this experience I would like to hear from
others using Patrol.  

If anyone has any hands on experience with performance
problems resulting from implementing the Patrol KMs
for Oracle, SQL Server or Sybase, I would appreciate
hearing about them.

Thanks,
