Barton, I am confused by several of your comments. Would you please clarify?
Trivial with ESALPS? - Ok, I believe you. Cannot afford to run something on Linux? - How does ESALPS gather the Linux process-level data outside of running an agent/application ON Linux? The data that Linux logged would be wrong? - I assume you are referring to the inaccuracies of the "tick based CPU time accounting"? - I had the understanding that RHEL5 and SLES10 resolved this issue with the new "virtual CPU time accounting"? - The memory, disk, #page faults, etc. are still accurate. Correct?

And you can not afford to run something on Linux that logs this information. And the data that Linux logged would be wrong anyway. You need something that combines the linux and z/vm data. Which none of what you have does. Morris, Kevin J. (LNG-DAY) wrote: > What tools are available to record/log Linux activity at the process > level? > > Scenario: > 1.
