Hi,
I've got DProf working successfully on a development modperl server
here. It is producing tmon.out files as expected:
proceed_id/tmon.out
Any given tmon.out file will contain all the timing information for all
scripts run under that process ID.
However, we want to work on allowing easy profiling of individual scripts.
One way that comes to mind would be to limit the number of scripts that
a mod_perl server will run to 1, before it reforks. Not exactly
efficient, but at least a single tmon.out file would contain one set of
timing information. A lot of files though...
In addition, we like having the single continous process up as it helps
us spot any accidental variable persistance problems.
So, can anyone suggest any good ways of splitting up the tmon.out data
into individual scripts? Or is biting the bullet and running the
"limiting" method the best way to go?
I don't think you have many other choices. httpd -X or in the
httpd.conf limit t he number of children to 1 and have 1 parent (prefork
mpm obviously)
You can always collate the output of each dprofpp tmon.out (sum them)
but you won't be able to isolate one script from another.

I never had a dream come true
'Til the day that I found you.
Even though I pretend that I've moved on
You'll always be my baby.
I never found the words to say
You're the one I think about each day
And I know no matter where life takes me to
A part of me will always be...
A part of me will always be with you.
