Re: [asterisk-users] Capacity of single instance of Asterisk
Hi Steve Thanks for your input. Please check my comments. I have a server with 24 cores running at 2.4ghz and 16 GB RAM. How many concurrent SIP sessions I can run from single instance of Asterisk on this server? I wish to use G711 codec with echo cancel. And all calls needs to be recorded. What kind of capacity are you looking to achieve? [Amit Patkar] Some where 2400 G.711 sessions with recording. So approx 1200 calls. From my experience, Asterisk is not really much of a RAM hog. A couple GB is good for a couple hundred simultaneous calls. With 4 'Intel(R) Xeon(TM) CPU 3.40GHz' cores, I can handle a couple hundred simultaneous non-transcoding calls with no recording on Asterisk 1.2. With 24 cores and 16 GB on tap, you will probably find other resource limitations before either CPU or RAM are a limiting factor. Personally, I'm a 'don't put all your eggs in one basket' kind of guy. Assuming a simplistic linear relationship between my host and yours, what will you do when it crashes with 1600 calls in progress? What will you do when you need to install patches or upgrade or ... I like a couple of instances of OpenSIPS in front of several Asterisk instances, even if OpenSIPS is on the same boxes as Asterisk. [Amit Patkar] I completely agree with you on distributing the load. At the same time, I am looking at juicing hardware as well. Can you share the number instead of saying couple hundreds? What will be impact on no of session when G729a is used? Significant. [Amit Patkar] Can I assume 30% reduction? Or it would be much more. -- Thanks in advance, - Steve Edwards sedwa...@sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000 -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Hi Kevin, Thank for your views. Where as no one is ready to share real numbers. I am looking at benchmarks so that I can plan for resources.

You have completely missed the point that other posters have made already on this list. Let me try to express it another way. Let's say that you were browsing at an engine manufacturer's website, looking at V-8 gasoline engines, and you found one that you liked, that you felt had a good combination of features for your project. If you then contacted the manufacturer and asked them 'how fast can this engine make a car travel', what do you think their response would be? Asterisk is a toolkit; it can be configured an infinite number of ways. Any performance measurements that are made and published apply *only* to the specific configuration that was measured; it may or may not be possible to extrapolate those into other configurations, or higher/lower capacities. There are lots of published numbers of Asterisk being used in various ways and for different purposes; whether any of them apply to your specific project is debatable, and relying on them for your project would carry some level of risk. Whether you are willing to accept that risk or not is up to you. In your specific case, as has been mentioned already, it is extremely unlikely that your proposed hardware would have any trouble with Asterisk 1.8 handling 2,400 SIP call legs (1,200 bridged calls), with the same codec being used on both sides. When you add in transcoding, that will change the system significantly, and depending on the codecs involved, the hardware may still be able to handle the load. I know from experiments I did years ago with an 8-core Xeon machine (2nd generation Xeon, so nowhere near as powerful as modern Xeon cores) that the Digium G.729 codec (software implementation) could handle over 800 channels with Asterisk 1.4; I think it's reasonable to expect that given the hardware you've proposed, transcoding 1,200 channels between G.711 ulaw and G.729A is likely to be achievable. Recording, though, is an entirely different matter. Again, since you haven't provided specifics, let's assume you are going to record the call legs 'as is' (in their native formats, unmixed). If you had 2,400 G.711 ulaw call legs to record, some simple math says that you'd need be able to push 150 megabytes per second of data onto your filesystem, on top of all the 'normal' work that Asterisk is doing. That's rather a lot, and will require that your filesystem and disk subsystem be extremely fast and well tuned. If the call legs were all G.729A, then the amount of data to write would drop to 18.75 megabytes per second, which is achievable even with inexpensive SATA disks. If you want the calls recorded in 'mixed' form (most likely in 16-bit signed linear PCM audio, since that's the easiest format to use outside of Asterisk), you'd double the amount of data going into the filesystem (now 300 megabytes per second) *and* you'd add in the CPU consumption of having to decode the incoming media streams and mix them. For G.711 ulaw this is pretty cheap and would likely not be an issue; for G.729A it's somewhat more expensive, but still might not be a problem given the amount of CPU capacity you have proposed.

Dual power supplies, two thumbs up but RAID 5 is only good for reducing storage costs on large volumes of data. It reduces performance and reliability over RAID 1. Don't put the OS on RAID 5 unless you like rebuilding servers from bare metal. It's much easier to rebuild and restore the data on RAID 5 sets if the OS is already up and running. Your OS and other system critical files (Asterisk) should be on RAID 1 for performance, redundancy and cost reasons. More disks = higher cost and higher chance of failure. Asterisk in general does not need much disk storage. The minimum drive size available in a new server tends to be overkill. Two drives as RAID 1 gives you redundancy and performance. Adding a third drive for RAID 5 adds cost, increases complexity and reduces reliability just to add storage capacity that you don't really need. (but the reseller WILL make more money and impress you with their command of the big words and acronyms on the spec sheet.) If and only if you need to store many hundreds of gigs of data (eg. recording a very large volume of calls) then RAID 5 becomes useful (or RAID 10 or RAID n).

Re: [asterisk-users] capacity
Having ventured high enough and far enough to view the curvature of the Earth and having stayed up late enough long enough (why do disks only fail at the weekend?) to rebuild and restore RAID 5 sets, I proffer the following (not so) Humble Opinion . Dual power supplies, two thumbs up but RAID 5 is only good for reducing storage costs on large volumes of data. It reduces performance and reliability over RAID 1. Don't put the OS on RAID 5 unless you like rebuilding servers from bare metal. It's much easier to rebuild and restore the data on RAID 5 sets if the OS is already up and running. Your OS and other system critical files (Asterisk) should be on RAID 1 for performance, redundancy and cost reasons. More disks = higher cost and higher chance of failure. Asterisk in general does not need much disk storage. The minimum drive size available in a new server tends to be overkill. Two drives as RAID 1 gives you redundancy and performance. Adding a third drive for RAID 5 adds cost, increases complexity and reduces reliability just to add storage capacity that you don't really need. (but the reseller WILL make more money and impress you with their command of the big words and acronyms on the spec sheet.) If and only if you need to store many hundreds of gigs of data (eg. recording a very large volume of calls) then RAID 5 becomes useful (or RAID 10 or RAID n). You should add this bulk storage IN ADDITION TO the mirrored pair holding the OS. regards, Drew Steve Totaro wrote: And I can post a link that shows a bunch of guys think the earth is flat with a 5/10 google ranking also (like the barf guys). http://www.alaska.net/~clund/e_djublonskopf/Flatearthsociety.htm I usually just call my guy at CDW and give him my needs, he is a former techie gone sales.

Re: [asterisk-users] capacity
I use standard wav (most compatible with players) so about a meg a minute. In my experience, most people (users) use their voicemail similar to email, they keep everything. Especially love struck college kids. I think Asterisk has a soft limit of 1,000 (maybe it is 999) messages as the max per inbox that can be changed in source. I suppose if you limit the max time allowed and the max inbox limit it might help but I think your 60GB estimate would be quite low in the real world. BUT, that is based on when I was in college and I was one of the very few to have my own cell phone (dating myself a bit). So in the real world, I am not sure how much use the system would actually see.

I have an Avaya Definity G3R. Calls to students will be routed through the G3R, to the Asterisk system so the caller can leave a message.

Re: [asterisk-users] capacity
I did basically the same thing via T1 on the Definity. It took a bit of tinkering on the Definity to get the coverage path right. For your use, I would go for a RAID 5, dual power supply box with quite a bit of storage. RAM and CPU should not be an issue with anything new. I would go with a T1/E1 card with more than one port just for future possible growth or options. Echo cancellation is probably not needed but if in the budget, it can never hurt (never say never, seldomly or rarely I guess is more appropriate). I would probably go with an HP DL380. The dialplan should be very simple. It should actually be pretty fun project.

Re: [asterisk-users] Capacity for transcode G711 to G729
Hi Matt, The best use I have seen is the newly converted IAX2 which can use multithreading in version 1.4, the beta of which should be released later this week. The best idea would be to compile Asterisk, run some tests (show translation recalc 60) with HT turned on, restart the box, bring it up with HT turned off and try again. What's the best way to know for sure that you've everything setup the right way to use HT with Asterisk? There're so many things, I'm not quite sure if I am turning or conversely not turning enough things on/off. I do the following right now: - in /usr/src, I have the symlink of linux and linux-2.6 pointing to the location of the src of the smp kernel like e.g. /usr/src/kernels/2.6.9-34.0.1.EL-smp-i686 - Then do a fresh 'make' on asterisk with these symlinks in placehe - Then reboot and turn on HT in the BIOS - Then reboot with the smp kernel Is that it? If I compile with the linux/linux-2.6 symlink pointed to the kernel of the NON-smp kernel, then reboot in the non-smp kernel but leave HT turned on in the BIOS, does it matter? would that be enough? or should i turn off HT in the BIOS as well to avoid it causing issues? In my experiments with using (*) inside of a VM and doing SMP I'd seen that simply booting into an smp kernel gave me timing issues even when (*) was compiled against a non-smp kernel source. I don't see these problems on a real machine but that's just one call. Who knows what'll happen if I throw 100 at it. Would love to see the results of this test you're setting up. At the expense of bandwidth, maybe I'll just stick with g711 all the way through and save money on g729 licenses and load on my machine. Any thoughts on g726? Would using g726-32 be a good compromise on bandwidth and cpu power instead of g711 or g729?

[Asterisk-Users] capacity testing
Hello all. I'm new to asterisk and have been using and testing it for about a week now. My initial hope has been to use it as a sip-h323 gateway to tie SIP H323 based ip phones together with my Cisco AS5300 and Lucent MaxTNT/MVAM networks. I am currently running Asterisk 0.5.0 under Redhat 9 on a single PIII 800 with 256megs RAM. I have tried a couple CVS version from the past week (maybe 01/09/04 and 01/14/04) and have not been able to get them to work semi-reliably in my simple 1 or 2 call test cases. v.0.5.0 has supported those ok. Primarily test cases have involved sending ip phone calls via SIP to Asterisk and having Asterisk route the calls using h323 via a gatekeeper to my TNT network which then sends it out the PSTN... and the opposite path, PSTN-TNT-Asterisk-SIP Phone. Another test has been sending a call from a AS5300 using SIP to Asterisk, out H323 to a TNT. Both of those have worked very well with the voice quality being excellent (actually better than a SIP-ISDN T1 hardware solution we've been working with - audiocodes mediant 2k for those interested). This is the test case I describe below as it was the one the allowed me to load Asterisk up with the most calls. Anyway, I know that what I'm doing is not exactly the intended primary use of Asterisk. That said, here's what I found. Voice quality was very good until I had approx. 25 calls up. At that point there were intermittent issues with garbled voice, a little echo, etc. When it reached a little over 30 calls, Asterisk just died (oops). During the test, I was trying to keep an eye on proc. memory util. Memory never seemed to be an issue - even right before the crash the Asterisk process was not using more than 20 - 25MB. Processor utilization was interesting to watch though. I couldn't make any direct/firm correlation, but it seemed like my spikes were coming when Asterisk was doing call setup. Even up to about 25 calls, utilization didn't spike to more the 25% for long, and with ~25 calls seemed to 'idle' around 15%. Above the 25 (when also started noticing voice quality issues), the proc. util. seemed to start going wacky - spikes up to 40, 50, even 60%. Then it went to 99% for a moment, voice quality was horrible if you could hear anything, and Asterisk crashed. I did not find anything in the logs to inidicate any problems, though I've found that to be the case pretty much everytime Asterisk crashes. I saw a list thread in which a developer asked for some gdb output... in it, he said this: Run asterisk with -vvvcg. Do your test (core file generated). Run gdb /usr/sbin/asterisk core_filename From within gdb run bt and send me the output of it. if it is of use, here it is (from asterisk v.0.5.0) - (gdb) bt #0 ast_smoother_feed (s=0xcbf90080, f=0x5de5c4a8) at frame.c:72 #1 0x41eb00b1 in oh323_write (c=0x8214488, f=0x5de5c4a8) at chan_oh323.c:1504 #2 0x0805884f in ast_write (chan=0x8214488, fr=0x5de5c4a8) at channel.c:1385 #3 0x0805afa1 in ast_channel_bridge (c0=0x5de5c4a8, c1=0x0, flags=0, fo=0x6ef20e50, rc=0x6ef20e54) at channel.c:2262 #4 0x418bdd7a in ast_bridge_call (chan=0x5de5ed98, peer=0x8214488, allowredirect_in=0, allowredirect_out=0, allowdisconnect=0) at res_parking.c:224 #5 0x41d6bfeb in dial_exec (chan=0x5de5ed98, data=0x41d6d19b) at app_dial.c:668 #6 0x08061a5a in pbx_exec (c=0x5de5ed98, app=0x80f0f98, data=0x6ef216e8, newstack=1) at pbx.c:396 #7 0x08068c61 in pbx_extension_helper (c=0x5de5ed98, context=0x5de5eeec longdistance, exten=0x8214488 H323:8257, priority=2, callerid=0x5de10048 \Jesse Peterson\ 2474766, action=1104606132) at pbx.c:1150 #8 0x0806392c in ast_pbx_run (c=0x41d6f3b4) at pbx.c:1634 #9 0x08069321 in pbx_thread (data=0x84a5038) at pbx.c:1855 #10 0x40026484 in start_thread () from /lib/tls/libpthread.so.0 - If anyone has tried something like this or has any comments, I'd be interested in hearing from them. jesse ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Asterisk does crash with the number of calls, but in my case, about or less than 20 calls, then I would get either a Segmentation Error and then crashed OR it would just crash saying Disconnected from Asterisk server all of a sudden. 2. I am using Pentium Xeon chip and hence more powerful than yours with 512M RAM, my CPU usage has always been low, however, I have not had a chance to look at the CPU usage just before crashing, but all the time that I was looking, it has been low. Rather the MEMORY has always remained high at 450M usage even with no calls. This is a different experience as compared to yours. 3. I have also noticed that with more calls, and after a certain random period of time, any H323 calls going into the Asterisk would fail, my AS5300 and MAXT TNT would get their calls all rejected from Asterisk. However, Asterisk was still running at the time and I could actually call in and out the zap interface and outbound H323 from Asterisk was not a problem. It seems that something got hung with H323, causing inbound H323 calls into Asterisk to all fail. In this situation, I would have to stop the Asterisk and rerun it to fix the problem. 4. I have not tried the 0.7.0 version, but with existing version, I am not getting reliable and stable system, nothing close to Cisco and Lucent which are rock solid. However, I really love the power and the features of Asterisk, and I remain in good faith to see improvements. Any associate out there who can shed some lights into this? I am rather curious as to why I seem to be using up all memory although I am not running any unnecessary processes, or should I actually disable all modules, other than really necessary ones to support VOIP?

Re: [Asterisk-Users] capacity testing
THat's not bad 20 calls through a 800Mhz P3. I new 3Ghz P4 could likely handle 60 then. Not bad. But don't beleive top. First off if acverages. Think for a minute. We all kow a CPU can never by 20% in use it is either in an idle loop (at 0%) or doing real work (100%) it can't be in an in-between state. I think with Asterisk what matteris is the probibility that when a packet comes in the CPU is idle and available to process it. When top says 20% that means that is only an 80% chance the CPU is free. Looks like 80 or 85 is about the braking point. Same applies to bandwidth. If a packets needs to go out, it needs to go out NOW not some time later if the sound quality is to be OK. So you look at the probibility of collision not just the available bandwidth. If your bandwidth is half used by, say web surfers, then half of your VOIP packets will be delayed. Jitter buffer can help, to a point. Back to CPU utilization: 30% utiliation means it is not available to handle a packet 30% of the time and that hansling must be queued up or delayed. --- Jesse Peterson [EMAIL PROTECTED] wrote: Hello all.

RE: [Asterisk-Users] capacity testing
I am rather curious as to why I seem to be using up all memory although I am not running any unnecessary processes, or should I actually disable all modules, other than really necessary ones to support VOIP? Do you mean that Asterisk is using up all of your memory or that all of your memory is i use? If the former, that's odd. But you should expect the later. Linux is designed such that it will always try to put almost all of your memory to good use. It will use extra RAM as a disk cache. So if you were to cut the amount of RAM in your system in half you'd have only slightly less free RAM as Linux would use a smaller disk cache Now if you say the Asterisk process in the idle state is 450MB then something is wrong = Chris Albertson Home: 310-376-1029 [EMAIL PROTECTED] Cell: 310-990-7550 Office: 310-336-5189 [EMAIL PROTECTED] KG6OMK __ Do you Yahoo!?

RE: [Asterisk-Users] capacity testing
I did initially, but I was having problems (possibly just in thinking it through) getting the provided h323 driver to either a) register as a gateway with my gatekeeper - that just does not seem to be and option (please correct me if I'm wrong!!!) or b) setup a 'variable' extension (yes, extensions.conf) that would allow me to route any number to it. jesse -Original Message- From: Alastair Maw [mailto:[EMAIL PROTECTED] Sent: Thu 1/15/2004 5:17 PM To: [EMAIL PROTECTED] Cc: Subject: Re: [Asterisk-Users] capacity testing On 15/01/04 19:39, Jesse Peterson wrote: #0 ast_smoother_feed (s=0xcbf90080, f=0x5de5c4a8) at frame.c:72 #1 0x41eb00b1 in oh323_write (c=0x8214488, f=0x5de5c4a8) at chan_oh323.c:1504 Do you experience the same problems when you use the other (bundled) h323 driver?

Sorry for the malformed mail. My responses are marked with '***' below. jesse == Hi, I am a newbie in Asterisk as well, intending to use it in a similar way as you are, communicating with AS5300 as well as other gateways including MAXTNT. I have had similar, but yet different experiences than yours. 1. Asterisk does crash with the number of calls, but in my case, about or less than 20 calls, then I would get either a Segmentation Error and then crashed OR it would just crash saying Disconnected from Asterisk server all of a sudden. *** The crashes I experienced were fairly transparent. When I had the console (asterisk -r) running, I saw the 'Disconnected' message you mention. 2. I am using Pentium Xeon chip and hence more powerful than yours with 512M RAM, my CPU usage has always been low, however, I have not had a chance to look at the CPU usage just before crashing, but all the time that I was looking, it has been low. Rather the MEMORY has always remained high at 450M usage even with no calls. This is a different experience as compared to yours. *** A Xeon of the same speed (800mhz in my case) should certainly perform better - lower, I don't know. I find it a little odd that you experienced basically the opposite of my testing. What version are you running? 3. I have also noticed that with more calls, and after a certain random period of time, any H323 calls going into the Asterisk would fail, my AS5300 and MAXT TNT would get their calls all rejected from Asterisk. However, Asterisk was still running at the time and I could actually call in and out the zap interface and outbound H323 from Asterisk was not a problem. It seems that something got hung with H323, causing inbound H323 calls into Asterisk to all fail. In this situation, I would have to stop the Asterisk and rerun it to fix the problem. *** Interesting - I have not experienced that (yet...). 4. I have not tried the 0.7.0 version, but with existing version, I am not getting reliable and stable system, nothing close to Cisco and Lucent which are rock solid.

I'm new to asterisk and have been using and testing it for about a week now. My initial hope has been to use it as a sip-h323 gateway to tie SIP H323 based ip phones together with my Cisco AS5300 and Lucent MaxTNT/MVAM networks. I am currently running Asterisk 0.5.0 under Redhat 9 on a single PIII 800 with 256megs RAM. I have tried a couple CVS version from the past week (maybe 01/09/04 and 01/14/04) and have not been able to get them to work semi-reliably in my simple 1 or 2 call test cases. v.0.5.0 has supported those ok. Primarily test cases have involved sending ip phone calls via SIP to Asterisk and having Asterisk route the calls using h323 via a gatekeeper to my TNT network which then sends it out the PSTN... and the opposite path, PSTN-TNT-Asterisk-SIP Phone. Another test has been sending a call from a AS5300 using SIP to Asterisk, out H323 to a TNT. Both of those have worked very well with the voice quality being excellent (actually better than a SIP-ISDN T1 hardware solution we've been working with - audiocodes mediant 2k for those interested). This is the test case I describe below as it was the one the allowed me to load Asterisk up with the most calls. Anyway, I know that what I'm doing is not exactly the intended primary use of Asterisk. That said, here's what I found. Voice quality was very good until I had approx. 25 calls up. At that point there were intermittent issues with garbled voice, a little echo, etc. When it reached a little over 30 calls, Asterisk just died (oops). During the test, I was trying to keep an eye on proc. memory util. Memory never seemed to be an issue - even right before the crash the Asterisk process was not using more than 20 - 25MB. Processor utilization was interesting to watch though. I couldn't make any direct/firm correlation, but it seemed like my spikes were coming when Asterisk was doing call setup. Even up to about 25 calls, utilization didn't spike to more the 25% for long, and with ~25 calls seemed to 'idle' around 15%. Above the 25 (when also started noticing voice quality

RE: [Asterisk-Users] capacity testing
Title: RE: [Asterisk-Users] capacity testing Hi all, and Jesse 1. So, you did get the experience of crashing all of a sudden with the "Disconnected from Asterisk server" error message. I got both this and the segmentation error when crashing. I am running the version of asterisk, libpri and zaptel updated to about 5 days ago, but I have had tested Asterisk for more than a month already and needless to say I have had this experience since Day 1, meaning it has always been a problem even in the previous revisions. Henceforth, I feel that it is an intrinsic Asterisk problem, rather than just the problem with specific versions / revisions. I have posted this problem a few times before, I feel that this is a major problem but surprisingly, I was not getting any feedback at all. I have this feeling that more than 90% of the Asterisk community is using the system for PBX application rather than VOIP, may be, just may be, Asterisk has not been tested with a good number of simultaneous calls. 2. I am using Xeon 2.6G chip, much more powerful than yours, I have not got any problem with CPU usage, at least not during the time that I was watching. The thing is when I start 'safe_asterisk' , I could see when doing a PID, 1 "safe_asterisk" PID session and at least 10 (or more especially when there are more calls) "asterisk -vvvg -c" PID session. Each session takes up about 18M to 20M RAM, when that is why I am seeing all very high memory usage. How many sessions of Asterick do you see running after you loaded it? 3. Are you running H323 (Jeremy) and OH323 (Michael)? I am running Jeremy's and have had this inbound H323 problem. I tried OH323 (Michael) as well, but for some reasons, I am getting this false connect signal, that is, I made an outbound H323 call to a CiscoAS5300 for example, I heard the ring and immediately on my "Asterisk", it showed call answered when it was still ringing. Do you have that experience?? What setting you have if you do not have that experience? 4. Lets talk off list at [EMAIL PROTECTED].

I know, but as I mentioned in the inital post, I haven't been able to get the last 2 cvs versions I've pulled to run stable enough to test. I've seen a 0.7.0 version number mentioned. Is there newer, mostly stable version of code I should try that just hasn't been officially released? jesse -Original Message- From: Jeremy McNamara [mailto:[EMAIL PROTECTED] Sent: Thu 1/15/2004 10:11 PM To: [EMAIL PROTECTED] Cc: Subject: Re: [Asterisk-Users] capacity testing Jesse Peterson wrote: I am currently running Asterisk 0.5.0 under Redhat 9 on a single PIII 800 with 256megs RAM.
