amxmodx profiler

This is a profiler built into amxmodx's core - it really is only useful to people trying to find bottlenecks in their plugins.

What is a profiler? It basically tells you how long your plugin spends executing stuff.

To install it, just replace the amxmodx_mm_i386.so or amxmodx_mm.dll files (remember to backup your old ones) with the provided binaries. You do not need to recompile any plugins or change any modules.

Then configure plugins to be profiled like you would to get plugins debugged.

There is a new cvar, "amx_profile", its configuration is identical to "amx_debug":
0 = no plugins will be profiled
1 = only specified plugins will be profiled (default)
2 = all plugins will be profiled

To specify a plugin for profiling (for amx_profile mode 1), open up plugins.ini, and after the plugin name, add "profile".

For example, "admin.amxx" would become "admin.amxx profile"

Note: You cannot profile a plugin in debug mode.

When a plugin is being profiled, there is a very slight overhead. It should be unnoticeable, and you should be able to profile plugins on a production environment.

At map change, all plugins that are being profiled will get their profile data appended to amxmodx/data/profiles/<pluginname.amxx>.txt

The profiler will read the time it takes to execute native calls, public function calls (from forwards), and function calls (direct public function / stock function calls).

Additionally, it provides two new natives (they are not available in amxmodx's official core) to allow you to profile special chunks of code yourself. Documentation for these is available in the "profiler.inc" file.

Source is available here

Any issues with this version post here, do not file a bug report for it.

Edit:
New version for 1.8.2 and bugs fixed is available here: https://forums.alliedmods.net/showpo...0&postcount=87

Here's an example profile report from admincmd.amxx

50 natives, 21 public callbacks, 33 function calls were not executed.

Type "n" is native call, type "p" is public function call from a forward, and type "f" is direct function call.

Note that it doesn't add up recursive calls.

For example: If function a() calls function b(), for the duration that b() is executing, the profiler for function a() is not keeping track of time. As soon as b() stops executing, a() will continue tallying up time.

sawce if I could steal that trophy of yours and re-award it to you - I would.

It's that amazing.

Your karma status could not be more accurate.

Re: amxmodx profiler

Irrefutable proof that there is nothing that sawce cannot do!

I need to steal this for SourceMod.

Re: amxmodx profiler

would it be possible for you to make something that logs at which function ( or maybe even the certain portion of the function ) a certain plugin is when the server crashes or reboots
