[Serusers] How to build in SER modules statically for profiling?
by 邹嘉 12 Aug '06

12 Aug '06

Hi, all! I am currently involved in a research work which aims at optimizing the SIP stack, and we chose SER -0.9.6 as our researching platform. we need to profile SER to find out which part(parser? network? transactions? ) consumes the most CPU cycles. However, tools like gprof and Intel Vtune's sampling tool can not show any information about the functions in dynamically loaded modules, such as tm, registrar. So, a possible solution seems to build in these modules into the core statically. I tried to do what the INSTALL doc says, compling with the following command:"make static_modules=tm PROFILE=-pg all", the final part of the result shows: ...... make[1]:***[callid.o] Error 1 make[1]: Leaving directory '/....../SER/ser-0.9.6/modules/tm' gcc -Wl,-02 -Wl, -E -pg action.o crc.o .....modules/tm/dlg.o, modules/tm/h_table.o .....modules/tm/uac_unixsock.o - gcc: modules/tm/callid.o:No such file or directory gcc: modules/tm/h_table.o:No such file or directory ... gcc: modules/tm/uac_unixsock.o:No such file or directory make: **[ser] Error 1 And if I proceed to type: make install the result shows: sr_module.o(.text+0xbc): In function 'register_builtin_modules': /.../ser-0.9.6/sr_module.c:89: undefined reference to 'tm_exports' collect2:ld returned 1 exit status make: ***[ser] Error 1 I am working with SER 0.9.6 And the linux kernel used in my machine is: Linux 2.6.9-22.ELsmp the OS used is Redhat 9 if anyone has tried the same thing or knows the solution, please let me know.Thanks very very much!

Re: [Serusers] Error using serctl monitor

which version of ser are you using? which version of serctl are you using? whats the output of 'serctl fifo which'? Could you set the "-x" option for serctl so that we see where serctl failed?

Re: [Serusers] How to build in SER modules statically for profiling?
by Jia Zou 12 Aug '06

　　Thank you for your kind help. However,my problem is to profile the shared libraries rather than to profile forking processes. gprof can not generate any information about these shared libraries, and i also seems problem when using sprof, which is said to be able to offer profiling statistics about dynamic loaded libraries. So, I think another way is to build these modules statically, but don't know how to. So can anyone help me with that? thanks for your time! Jacqueline Zou ======== 2006-08-11 14:56:12 您在来信中写道： ======== Your post belongs to serdev. Here is a serdev post from Hendrik Scholz some time back. g-) Hi! I'm about to profile our SER installation and since profiling doesn't run out of the box here's a rough guide: - you'll need to build SER from sources, thus get sources, apply your patches and so on - before compilation get this patch (for CVS HEAD): http://dump.wormulon.net/patches/ser-profiling.diff Call $ patch -p0 < ser-profiling.diff from the SER base directory. What it does it invoking monstartup() in each child process since the profiling information get lost when fork()ing. I added all childs including timer and fifoserver. If you are only interested in certain worker processes you can cut down the resource impact by selectively activating profiling. - enable profiling in Makefile.defs - Set both -DPROFILING and PROFILE=-pg - compile and deploy as usual - Before starting SER using your standard init script you need to set an environment variable that acts as a prefix to all profiling data files. If you don't set it you'll only get one file for the main process. # export GMON_OUT_PREFIX=testrun The gmon files will be named testrun.<PID> with the PID matching $ serctl fifo ps SER may change the current working directory and drop privileges on the way therefore I suggest you invoke the init script from the SER working directory (-w option) so you'll end up with all files in one place. - Run SER for a while. Not all gmon files will show up immediately, though. - You should now be able to get per-process statistics using $ gprof /usr/sbin/ser testrun.<PID> - If cummulative statistics are what you are looking for use $ gprof -s /usr/sbin/ser testrun.* to create a new gmon.out which contains statistics over all processes. I have yet to fully analyze the results.

[Users] LCR load_contacts and load_gw
by Helge Waastad 11 Aug '06

11 Aug '06

Hei, I wonder if someone could comment on this: I have several cisco gateways distributed all over and are using the lcr module for this. Is it possible to combine both load_contacts/next_contact and load_gw/next_gw (I have softphones also registered with the same numbers that are behind the gateways.....) Would it be interesting to have regexp in prefix matching aswell? ex: 4675[1-2] ? br hw

[Serusers] ser SDP rewrite problem, rtpproxy is not working !!!
by Sebastian Gabris 11 Aug '06

11 Aug '06

Hi, got also this problem, did you find a solution? Sebastian hello there, I am working on SER with two network interfaces. EP1--------------->(172.16.16.160) SER (192.168.5.1) -------------> EP2 what happens, SER receives invite from EP1, it reinitiates invite for EP2. now what it does is that it writes the external IP i.e. 172.16.16.160 in the SDP contact info, where as it should be the internal one i.e. 192.168.5.1 ... now I want to overwrite the SDP contact info in that invite. I have got two options to do it one option is to use force_rtp_proxy("ei", "192.168.5.1") or use sdp_mangle_ip() function of mangler.so . but they are not working for me. when I play around with force_rtp_proxy function rtpproxy get crashed and sdp_mangle_ip() is not behaving properly ...... whats your experience ? I have used ser-0.8.14 and now using ser-0.9.0 with cvs rtpproxy. I am running rtpproxy like rtpproxy -s udp:192.168.5.1 -l 172.16.16.160 and I am using this line in ser.cfg modparam("nathelper", "rtpproxy_sock", "udp:192.168.5.1") I am really stucked please help !!!! thanking you regards, -- Atif ______________________________________________________________ Verschicken Sie romantische, coole und witzige Bilder per SMS!

[Serusers] Problem with incoming calls
by Sebastian Gabris 11 Aug '06

11 Aug '06

Hi everybody, Like told in the subject i got problems with incomnig calls, SIP signalling works but RTP doesnt. When I make a call from my UA to the VoIP-Provider all works well, sip & rtp. I start rtpproxy in bridged mode: rtpproxy -l publicIP/privateIP. I use this scenario: UA(private IP) <-> (privateIP) SER (publicIP) <-> VoIP-Provider i try to figure out where my mistake is in this config file: route[1] { if(dst_ip == 10.245.104.68) { force_rtp_proxy("","193.77.54.68"); } else { force_rtp_proxy("","10.245.104.68"); }; t_on_reply("1"); if (!t_relay()) { sl_reply_error(); }; } onreply_route[1] { if (status =~ "(183)|2[0-9][0-9]") { if(dst_ip == 10.245.104.68) { force_rtp_proxy("","193.77.54.68"); } else { force_rtp_proxy("","10.245.104.68"); }; }; } By the way, is there a option to view rtpproxy debug info?
