Hi,
I have the need for a simple profiling capability for mod_perl applications.
At a few (< 50) points in my code I want to call something like:
$profiler->mark("some identifier");
and increment the counter for "some identifier". Later I want to be able to get
(through a web page) a summary (grouped by identifiers) of all the
profiling calls
made (of course, made by all Apache child processes.) For instance, if I want
to profile the number of times a particular subroutine was called, I would use:
sub mysubroutine {
$profiler->mark("in mysubroutine");
...
}
This is very similar to logging, except for the summary part. Does anyone
have ideas of a good way to implement this? Shared memory? An external
daemon to record these calls? Has someone already implemented this?
Robust and simple are good.
Thanks,
ER
