ThreadDumpScan tool for garbage collector trace analysis

[Former Member]

Hello,

I would like to use the non official SAP tool ThreadDumpScan in order to have these nice graphs concerning the garbage collection.

I have downloaded the std_server0.out from my server, where I can find my GC activity, for instance :

...

<GC(1): Bytes Traced =0 (Foreground: 0+ Background: 0) State = 3 >

>> 2 modes = 2,0 (0) free After GC (reg,wild):1414879256,644244672

<GC(1): GC cycle started Wed Apr 18 01:53:12 2007

<GC(1): heap layout: (1464142288/1503237440) (644244672/644244672) /0>

<GC(1): freed 49263032 bytes, 98% free (2108386960/2147482112), in 194 ms>

<GC(1): mark: 171 ms, sweep: 23 ms, compact: 0 ms>

<GC(1): In mark: root scan 150 ms>

<GC(1): refs: soft 260 (age >= 0), weak 0, final 385, phantom 0>

<AF[1]: completed in 214 ms>

...

But the thing is that when I run the command "DumpScan.bat std_server0.out", I get the following error :

no -verbose:gc output found

On a former project, it was working properly, so I do not know why I get this error. The std_server0.out seems fine. I have gone through all the documentation provided with the tool but nothing in there, and the available documentation on this tool is very poor on sdn. Does anyone know what could be the problem ?

Thanks for your help,

Best regards,

Guislain Libessart,

Did you ever get this tool working? I am having the same issue.
