Pinned topic lpcpu - a Linux performance customer profiler utility package

‏2012-09-27T13:22:51Z |
Increasingly, we're taking advantage of a package of scripts to capture and format system information for performance analysis.   This package is a derivative of an automated performance infrastructure used inside of IBM for performance testing, analysis, and controls - so this quite literally is an example of sharing what we're using everyday.
 
The "lpcpu" package - available on this page - provides for an easy script to run which gathers a lot of the information generally needed to understand, debug, and analyze performance problems.   The script runs on both x86 and on Power systems.    Additionally, post-processing and formatting of the results is available from an x86 based Linux system (the graphing routines depend on an x86 charting library).
 
In this message board thread, we'll post the updates made to the package, hints and tips, and news.   I would encourage you to click "notify me" on this message thread to automatically get the updates.

    An update was made this morning to remove the profiler termination messages.   The termination messages from kill'ing the mpstat, vmstat, iostat (etc) profilers was disconcerting for new users of the scripts.  
     
    Additionally, a small fix to the formatting of the mpstat output to graphs was corrected in the case where an LPAR had no CPUs assigned in one of the NUMA nodes.

     An update to lpcpu.tar.bz2 was made this morning.     A number of post-processing routines were updated and corrected for special case conditions with meminfo and sar.   The sar generated charts were clarified to show consistent metrics for throughput (KBytes/second) and packet size (Bytes/packet).
