Error: No data to return.

Oct 2, 2012 at 4:02 PM

I created log file on win 2008 R2 and tried to process it using pal 2.1 on the same server but I got the following error (so trying to open log generated in newer win version is not the case). Please advise:

C:\perflogs\PerfLog_BL_DEVSPBQA03.blg (Binary)

The log isn't corrupted and can be opened.

According to Relog.exe there is only 4 samples of data in the log. This is not enough data for PAL to properly process. The log needs at least 31 samples before it can be processed using the PAL tool. Also, be aware that you are using an older version of PAL consider using PAL v2.3.2.

Thanks for quick response. The issue wasn't connected with PAL. The root cause was the list of counters to collect. If you add 'Processor' counter then don't forget to add  'Process' counter. Because w/o it in my case relog.exe returns error described above.

You can export a counter list from the PAL threshold files by clicking on the Export to Perfmon Counter Template button. This will ensure that you are collecting all of the counters that PAL intends to analyze.
