[System.Char] doesn't contain a method named 'substring'.

description

Hi Guys,
 
I'm getting the following error when trying to analyse a csv log. Looks like something other than a string is being sent to the GetCounterComputer function?
 
Method invocation failed because [System.Char] doesn't contain a method named '
substring'.
At C:\Program Files\PAL\PAL\PAL.ps1:1165 char:29
  • If ($sCounterPath.substring <<<< (0,2) -ne "\")
    • CategoryInfo : InvalidOperation: (substring:String) [], ParentC
      ontainsErrorRecordException
    • FullyQualifiedErrorId : MethodNotFound
       
      I used relog.exe to convert a .blg file from a Windows Server 2003 server with Exchange 2003. Then I ran PAL Wizard v2.3.2 against the csv with default settings.
       
      Any help would be great as this looks like a great tool if I can get it working.
       
      Cheers,
       
      Dave

Don't worry about this one. I think it was just a corrupt csv. I exported the Exchange 2003 template and used that in PerfMon and that analysed fine.

I am seeing this error with blg files for a custom xml (attached), analysing a single counter for a product i'm troubleshooting. I have tried it with three separate blg files with the same error.

I think i cribbed relatively accurately, although quickly, and did not take time to determine if my series syntax is particularly correct.

I will dig in as time allows, and my powershell is serviceable, but if anyone has any insight I would be grateful.

kind thanks,

mike

Hi mcstf, can you send me the BLG file that you are using? If it is larger than 4 MB, then consider putting up on a free Microsoft Skydrive.

Clint, just got emailed for your response this morning.

blg is on a spideroak share:

https://spideroak.com/browse/share/cannel-dot-la_netshare/pal_is_an_absolute_godsend

This is a little 5MB one--a one-week run is 160MB--but they all exhibit the error.

Hi mcstf, I received your counter log and custom threshold file. It processed just fine for me. I am using PAL v2.3.3 which I am going to release later today. Try it out with v2.3.3 and let me know if you still have problems with it.
