I like doing "serious work" in an AGI instead of the dialplan because: 1) It allows me to use a compiled language. Not just for performance reasons, but because a compiler (or a strict interpreter) helps me protect me from me. My production dialplan is just over 600 lines. The sources to my AGIs are a bit more than 15,000 lines. I like that if I "fat-finger" a variable, the compiler will help me. If I "fat-finger" something in 16,000 lines of dialplan will I ever find it? 2) It allows me to hide complexity. I like having a single statement in my dialplan that says "agi(block-ani)." I know that in this single statement I am invoking code that acts as the gatekeeper to my system, allowing me to block callers by area code, area code and prefix, and the complete subscriber number. I know it works well and I don't have to look at it any more. 3) I can "share" better.

Re: [asterisk-users] need examples of asterisk and mysql integration
I did not mean to stir up a hornet's nest or religious war :) The BASIC QUESTION I was trying to ask is this... "Since the MYSQL add-on provides a way to interface with MySQL what is it that one gains or is trying to gain by writing their OWN AGI script to do the interface ?" The only reason I mention this being a "performance hit" was that the book ATFOT mentioned that AGI scripts in general were less efficient and therefore one should do all possible work in the dial plan. Maybe this is true, maybe this is not true. Regardless. I would just like to borrow from the expertise and experience of other and ask the BASIC QUESTION above and hope that folks will share their experiences. I'm pretty sure they did what they did for very very good reasons that I am just not experienced enough yet to know. So The answer to the questions is ???

There's a difference between C and a dynamic language engine (such as perl and PHP). To give you some idea of that, let's look at some "do nothing" loops. # For a base line: pure internal shell: $ cnt_list=`seq 100`; time ( for i in $cnt_list; do :; done ) real0m0.001s user0m0.000s sys 0m0.000s # What happens if I run a subshell? $ cnt_list=`seq 100`; time ( for i in $cnt_list; do (:); done ) real0m0.240s user0m0.036s sys 0m0.204s # Now a small C program: $ cnt_list=`seq 100`; time ( for i in $cnt_list; do /bin/true; done ) real0m0.272s user0m0.052s sys 0m0.216s Slightly worse. Now a very minimal perl script: $ cnt_list=`seq 100`; time ( for i in $cnt_list; do perl -e ''; done ) real0m0.570s user0m0.220s sys 0m0.352s # Not so bad, right? But it didn't actually have to compile anything. # Let's give it something to compile: $ cnt_list=`seq 100`; time ( for i in $cnt_list; do perl -MCGI -e ''; done ) real0m4.447s user0m2.884s sys 0m1.564s # Likewise PHP5 $ cnt_list=`seq 100`; time ( for i in $cnt_list; do php5 -r ''; done ) real0m3.241s user0m1.524s sys 0m1.716s # Python: $ cnt_list=`seq 100`; time ( for i in $cnt_list; do python -c ''; done ) real0m2.618s user0m1.684s sys 0m0.932s As you can see, each of them used way more than one second of pure CPU time for 100 runs (except the C one, and the perl-without-modules one).

Re: [asterisk-users] need examples of asterisk and mysql integration
At 02:58 PM 4/23/2008, you wrote: Re performance hit. I actually re-wrote one of my frequently used AGI in "C" and even set the STICKEY-BIT to avoid reloading the static text portions. I noticed slightly lower disk activity level (but the perl file was probably in memory cache too). So keeping it memory resident with stickey-bit probably was not really needed. But I did see a drop in over-all memory usage. Alas, none of these 'savings' were big enough to matter. I notice same performance level regards number of simultaneous calls - - - but that too was moderated by eternal load balancing distribution to multiple Asterisk gateways. For a slightly different twist. I re-designed the AGI to be only a message-passing function that talked via SOCKET to a always running service. I let that service do all the heavy lifting DB work and the AGI itself only asked questions and got replies. Again, no measurable difference in performance. So, I summarize to say that with over 6,000+ simultaneous call on 60 different Asterisk boxes, there was no difference in OPERATIONAL performance that the human operators could measure. Since any one box was running a balanced distribution, the large peaks of inbound calls did cause a problem either. The CPU cores (dual core Xeon) were seeing about the same utilization levels with lots of idle time left over. Probably because I was using more lower cost boxes spread about the US rather than fewer large boxes with a greater number of calls per box. As several folks have commented, everyone should write your AGI in whatever language you feel is best for your long term support needs because that is where your real costs savings are to be found.Getting a few more cycles from the CPU by squeezing the programming is not high on my list of priorities. IMHO, My suggestion to use perl AGI still stands as good advice on any current technology machine. ..mike.. ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

AGIs do not have a substantial "performance hit" and I think people need to get this misconception out of their heads. Writing AGIs in a scripting, non-compiled language may be great for prototyping and proving concepts where performance is not expected to be an issue. Personally, I don't write AGIs in anything but C. It's the sharpest tool in my kit and I know it best. A lowly 1.6GHz Celeron can execute over 100 AGIs per second. I strongly suspect that the "startup hit" will pale to the "interpretation hit" of the dialplan script quickly. AGIs are a wonderful resource. You get the execution speed of an application (minus the usually insignificant startup hit) in a "sandbox" environment where you can't crash Asterisk and debugging is a couple of orders of magnitude easier. You can even write multi-threaded AGIs if needed. If you don't need to access the internals of Asterisk an AGI beats an application in my book. Maybe I should write one... I guess some day I'm going to have to cobble up one of my 2,000 line AGIs (written in C) in "dialplan" so I can speak with authority from actual experience. However, the absence of facts has never stopped me from expressing an opinion :) It seems that "compartmentalizing" a boat load of complex code in "a real language" (ducking quickly out of Tilghman's death glare) to be so natural to me for so many reasons I don't know where to start. So I won't.

Hi, With AGI you can write logic in whatever language fits you best. if you like perl, use the asterisk-perl stuff. if you like php, you can use the native mysql stuff if you like bash, you can use the mysql commandline client etc etc You can even use the MYSQL dialplan functions.
