+NAME
+ RT::Extension::Log::MemoryUsage - log information about memory used by
+ RT processes
+
+DESCRIPTION
+ RT is a big application with many modules, extensions and different ways
+ to run system. As well, there are tons of ways to screw up memory usage.
+ It's hard to detect memory leaks and not only them, but just places in
+ code that like to eat lots of memory.
+
+ Purpose of this extension is to help identify requests that cause a
+ memory usage spikes.
+
+AUTHOR
+ Ruslan Zakirov <ruz at bestpractical.com>

+ Under the same terms as perl itself.

+RT::Extension::Log::MemoryUsage - log information about memory used by RT processes

+
+RT is a big application with many modules, extensions and different ways
+to run system. As well, there are tons of ways to screw up memory usage.
+It's hard to detect memory leaks and not only them, but just places in code
+that like to eat lots of memory.
+
+Purpose of this extension is to help identify requests that cause a memory
+usage spikes.

DESCRIPTION
+ This extension helps identify requests that cause a memory usage spikes.
+
RT is a big application with many modules, extensions and different ways
to run system. As well, there are tons of ways to screw up memory usage.
It's hard to detect memory leaks and not only them, but just places in
- code that like to eat lots of memory.
+ code that like to eat lots of memory. This extension reports memory
+ usage changes after each request to the server. Unix `ps` command is
+ used to get this information.
+
+INSTALLATION
+ perl Makefile.PL
+ make
+ make install
+
+ Change RT site config according to "SYNOPSIS", restart server.
+
+RESULTS
+ When RT handles a request this plugin logs two messages. Before the
+ request and after. Something like:
+
+ memory after '/index.html' =>
+ pid: 25956; rss: 55380 (+20); rsz: 55380 (+20);
+ vsz: 129168 (+144); tsiz: 0; %mem: 2.6;
+ memory before '/index.html' =>
+ pid: 25956; rss: 55360 (-20); rsz: 55360 (-20);
+ vsz: 129024 (-144); tsiz: 0; %mem: 2.6;
+
+ Message issued before request shows change in memory usage since
+ previouse request to this process. Usually it shows negative numbers,
+ except for request after first touch of a component. Negative numbers is
+ a result of taking sample a little bit earlier after request when some
+ memory is not freed yet, but it is free before next request. As you can
+ see above in example all additional memory was freed between requests.
+
+ When a page requested for the first time then usually numbers don't
+ match. This happens cuz perl have to compile new code and that code
+ stays in the system for the whole time.
- Purpose of this extension is to help identify requests that cause a
- memory usage spikes.
+ However, if you have a page X and constantly next request doesn't
+ reclaim all memory before then you have a memory leak.
