Re: [asterisk-users] Concurrent calls including mysql taking lot of time for execution
Thanks Dave, I added a new SSD harddrive instead of a normal SATA harddrive as well as included my ip in the hosts file also I have included 'skip-name-resolv' as you mentioned to not to resolv and tested for around 250 concurrent calls, connection was going through fine...next week I would be testing it for some more additional calls..Thanks for all your replies.

Re: [asterisk-users] Concurrent calls including mysql taking lot of time for execution
I think the key point is how many calls per second. That's what mysql is concerned about. Other than that it is just asterisk.

I'm not a big fan of doing anything performance sensitive in scripting languages. I'm also not a big fan of doing MySQL in dialplan. I think it makes for a very ugly and difficult to maintain dialplan. Since there is no substantial syntax checking, every time you edit your dialplan you risk fat-fingering something that you (or somebody less skilled than you) may not notice and may take considerable effort to debug. When the live calls are made to test and at 200th or at around 250th call there is a point where it took like 5-10 sec just to connect to the database and in the mean time we get dead air for that period of time..how can we change the type of connection that you mentioned? Since I don't do MySQL in dialplan, I may be wrong here, but in C all you have to do is change the host (or IP address) to localhost. I'd take a look at using AGIs written in C. They make nice little building blocks. They execute very quickly and can cleanup your dialplan. Here's how I broke down part of a recent project: ) block-ani -- lookup the caller's ANI in the database and set STATUS (a channel variable) to BLOCK, PASS, FAILURE. ) lookup-dnis -- lookup the dialed number in the database and set a bunch of channel variables from the database. My current project sets around 350 variables in the blink of an eye -- at least less than a second. Sets STATUS to SUCCESS or FAILURE. ) auth-card -- creates a thread to play Please hold while your card is being verified... while the mainline code checks to see if the credit card is in a known bad database and issues an authorization request via TCP to the card processor. Usually we get the response before the prompt completes playing so it appears instantaneous to the caller. Sets STATUS to SUCCESS or FAILURE. ) messages -- kind of like a voicemail system where callers can record messages for other callers and listen to messages left for them. Lots of database activity. ) most-idle-agent -- find the online agent who has been idle the longest and has the skills (from the database) needed for the caller. Sets AGENT (a channel variable) to the agent's ID or GROUP. ) settle-card -- called when the caller hangs up, rates the call based on how much time they spent in each product and issues the card sale request. Most of these could have been done in the dialplan, but it would have been completely un-maintainable and prone to failure. Or might be is it good to go with dual quad core processor instead of just one inorder to handle the call capacity as well as connections? I'm not a big fan of throwing hardware at something that may be easy to fix. What will you do if your business doubles? You mentioned 400-500 simultaneous calls. You may want to re-think your architecture to split that across several hosts. I'd rather tell my client a host smoked and only took 100 calls with it -- each call in the above project is worth about US$30. -- 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 -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

The thing is, concurrent calls won't make any difference, it's the calls per second. And really you're unlikely to use too many queries per sec. Seriously, use at least AGI (fastAGI would be better but AGI will at least give you a start). So: 1. Do you get the same delay if you use MySQL command line at the same time? 2. Do you have a programming language you know well enough to connect to MySQL in? -- Cheers, Matt Riddell Director ___ http://www.venturevoip.com/news.php (Daily Asterisk News) http://www.venturevoip.com/st.php (SmoothTorque Predictive Dialer) http://www.venturevoip.com/c3.php (ConduIT3 PABX Systems) ___ -- 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 ___ -- 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

If you're referring to debugging outside of Asterisk, it's dead obvious -- once you know the secret. The AGI protocol is just communications over STDIN and STDOUT in a specific format.

Re: [asterisk-users] Concurrent calls including mysql taking lot of time for execution
There were 2 problems that we faced, one was at around 50 calls, few calls were just dead air, and when I saw the logs I could see that it was sent to the sip provider and after that there was no log for that particular call that was having dead air, but at around 200 to 250, we could see that MySQL(Connect connid ipaddr uname pwd db) statement took around 5-10 sec to connect to the database and then the 2 queries in that code got executed pretty fast (1-2sec), and so here we had the dead air untill the call got connected (after 5-10sec). We also monitored the processor usage and it was around 15-20% CPU and memory was around 300M to 400M, so we concluded that it was not the hardware issue.based on all of your opinions i will try to see whether I can use any other language and try to do those operations.Thanks for all of your information!
