Are you using https://metacpan.org/pod/Catalyst::Log for your own
application-level logging?
This would be step one.
For performance testing, memory leaks, etc. I'm sure there's plenty of
options on CPAN?

Dear all,
I'd need some help with debugging and monitoring an apache2+fastcgi
production environment ...
... i did not find any information about that online ?! :(
what i would need is logs of the fcgi processes that show:
* the request IP, url and paramters
* how long it took to answer a request
* cpu+mem usage of each process
putting a catalyst application into Debug-mode is one option;
but thats not clever for a production environment ... and its pretty
hard to scan through all that information.
any ideas ?
the story behind....
We are running a bunch of Catalyst applications in an Apache2 and
FastCGI production environemnt.
Since a few days it happend 2 times, that one of these applications ran
really "hot";
the fcgi processes of that application used 4times more ram and constant
high CPU-usage.
the result was, that apache spanned lots of processes trying to answer
all requests;
so at the end *all* requests to apache2 returned a "timeout" ..
i tried to find out what the problem was; grubbed through lots of apache
access logs without any reasonable result :(
i'd be thankful for any hints how a catalyst+apache+fastcgi environment
can be monitored ..
thanks alot,
bernhard
