tlviz-format crashing ... why?

Hi all,

I'm using the tlviz-formatter to format EVAperf output (we don't have Storage Essentials to generate pretty graphs for us).

Each time I run it I get the following error:

Run-time error '457':
This key is already associated with an element of this collection

The EVAPerf output is in CSV format and I'm sure it's valid.

Can anyone suggest what might be causing this? I wrote in a previous ITRC forum post http://forums11.itrc.hp.com/service/forums/questionanswer.do?admit=109447626+1268935835923+28353475&threadId=1382218 that I fixed it by making sure the .MDB file was writeable - that didn't fix it this time though.

The error always occurs while trying to make the Host Stat file ...

Re: tlviz-format crashing ... why?

Hi Chris,

Ensure two following things:

- Command & syntax used to capture the data - evaperf all -cont XX -dur YYY â csv â ts2 -fo data.csv
- TLViz Formatter version is tied with EVAPerf Versions - So, you need to use same version. No backward compatibility.

There is an "Run time" error with Tlviz Formatter fixed in latest version(v9.2) â The problem with an undefined port in the evaperf hc command causing a run time error in TLVIZ Formatter has been fixed.
