    What is it for?

    It is intended for advanced users to measure per-plugin / per-function (including internal game function) performance.

    See an example of the final report attached to this post.

    Description:
    Provides an easy way to run a valve profiler with one single command and save a log to a separate file.

    This is actually a shortcut for "sm prof*" + some internal game commands.

    This is the only correct way to run profiler for L4D series games without a crash. For details, see the issue.
    EDIT. That bug was fixed in SM v1.11.6726.
    Graph includes:
    - Game + plugin functions call stack
    - Function list sorted by max number of total calls
    - Function list sorted by Avg time/Frame
    - Function list sorted by Avg time/Call
    - Function list sorted by Avg time/Peak
    - All of the above separately with / or without children calls
    WARNING
    - Be careful, if you install it on the Live server! Stopping the profiler will cause a significant lag due to the analysis process. Actually, it can freeze you > 10 sec.
    - You may want to disable a watchdog by putting the following argument in server startup options, otherwise the server can exit with timeout (thanks to peace-maker for the suggestion):
    Code:
    -nowatchdog
    and possibly, "SlowScriptTimeout" "0" in /sourcemod/configs/core.cfg
    - It's better to run the profiler for a short period of time.
    - The longer it is running, the longer the analysis process will take.
    Direct analysis of profiler logs is not provided in this topic.
    Create your own topic in "General" section of the forum to get some help.

    Requirements and Compatibility:
    - SourceMod v1.11.6726+
    - Any SM compatible game
    - Carefully read "WARNING" section above !!!
    ConVars:
    - Nothing

    However, there are other game ConVars you may want to check on your own:

    For some reason it's not producing logs for me, I've loaded the plugin manually and made the suggested changes.
    The debugger starts and freezes briefly on stop, but there's no logs anywhere.

    Game? Platform?

    Well, it seems Valve broke "con_logfile" ConVar in the latest Left 4 Dead 2 update. I opened the issue.
    You can still retrieve the profiler's log from console.log until I push the update.

    I'm still unable to have any logs saved, it seems to not "finish" properly.

    If I start the debugger, and end it after a bit, it'll print out that it's saved, but the file doesn't exist.
    When starting it again later, the server fps is significantly lower than what it was the first time I started the debugger, making it seem like something else is still running.
    If I keep starting and stopping it, the server fps will dip lower and lower (turning it off does return the server to its full performance however)

    I've no idea why that happens to you.
    Try to enter such commands in rcon manually and see what's reported to you.
    Code:
    vprof_on
    sm prof start vprof
    sm prof stop vprof
    sm prof dump vprof
    vprof_off

    It prints to console as expected, it just won't dump it for some reason?
    I couldn't find it in the console log either.

    So, did you receive the output of the profiler in rcon console similar to the one attached in 1st post?

    Try to add such arguments to server startup options:
    Code:
    -debug -condebug -console -usercon -nowatchdog
