<snip> Just went live with z/OS 1.7 and noticed that CPU consumption by Omegamon/MVS has gone up dramatically (CMS and HIST tasks) like +50% or 4 to 6 MIPS (FSVO MIPS. </snip>
In 30+ years with various flavors of OM, I have found that there are really only 2 things that seem to matter. 1) Auto refresh interval. Although in repeated studies over the years I have never been able to measure the impact of a difference between say a 5 sec refresh and a 30 sec refresh. Yes the resource consumption did change, but I could never find any impact at the application level. If you don't have sufficient precision to measure it, does it really make a difference? 2) The OM DASD utilization functions can consume significant amounts of resource, especially if duplicated functions occur. (e.g. gathering DASD cache information on more than 1 LPAR). There are several IBM Info APARS on this and probably also on the RMF page. A similar argument would apply to the OM functions, so check them out. All of that being said, I don't have any specific info related to z/OS 1.7.
