Learning using PAL

Editorial architecture visual showing system boundaries, service interaction, and technical tradeoffs

PAL is good, producing good quality report, as usual, the learning curve is not cleared documented.

  • Problem: MergeConvertFilterPerfmonLogs : Relog.exe failed to process the log
    • fixed this by adding the monitored performance counters in the blg file
  • Problem: CheckPalXmlThresholdFileVersion : The threshold file specified is not compatible with PAL v2.0.
    • for whatever reason, the custom.xml supplied in codeplex download package is not correct, fixed by copy structure from systemoverview.xml
  • Problem: MergeConvertFilterPerfmonLogs : ERROR: Not enough samples in the counter log t properly process.
    • quite intuitive, just add more samples by sample intervals

Overall, good tool, of course much better than eyeball the performance counters!

    Hi there,

    Clint Huffman did a great job with PAL. I just had following Issue.

    [PAL crashed with [MergeConvertFilterPerfmonLogs] ERROR: Unable to find the converted log file …]

    In this case the cause was that the .blg File (permon trace) came from a initial in english installed server that had a german ui language pack installed afterwards.

    So PAL only speaks english therefor the .blg has to be translated into en-US. You can do this with the Perfmon Log Translator, written by Sven Haubold, and available at codeplex.

    After coverting the .blg the PAL Script worked like a charm.

    all the best,
    Florian
