I would need to see the client console output, at least, to analyse
the problem. However, before going into details, I would suggest that
you try following the step-by-step instructions at

Recent version of Polygraph come with Report Generator. The generator
is a much user-friendly tool than a low-level lx.

This is a desired behavior. Move the old log files or use different
names for the new files if you do not want them to get overwritten.
There is no good reason to have two experiments logged in a single log
file (besides creating more mess and confusion).

I do not believe it. If you are specifying the same log file, it will
get overwritten.

No. One log per one polyclt/srv process per one experiment.

The log file is created under the name you specify with the "--log"
option. You can view comments in that file by running lr. For example,

Please use the latest stable version of Polygraph (2.5.4). With that
version, you would be able to run "lx /tmp/tc.log" to get all objects
at once. Again, the Report Generator is your friend here; you do not
need to use "lx" if you can find all the required info in the
generated reports.

Yes, you can. Simple.pg workload is not appropriate for any kind of
testing though. It is provided as the example to start with only.

Sure. Use different log file names for each experiment:

> polyclt ... --log /tmp/clt.nopxy.take2.log
> polyclt ... --log /tmp/clt.polymix3.take1.log

...
Make sure you have enough space where you store log files.
Good luck,
Alex.
