[Serusers] Logging Capabilities
by Ricardo Villa 27 Mar '03

27 Mar '03

Hi, I would like to know if it is possible to append a variable to a log command like: log(1, "Register received \n"); For troubleshooting purposes I would like to be able to see a log in syslog that would say something like: "Register received from subscriber= ricvil" Is it possible to do something like? log(1, "Register received from subscriber= $username\n"); I could not find any documentation to support this. Thanks, Ricardo

RE: [Serusers] Accounting Script
by akfullfo＠august.com 27 Mar '03

Well, I have no problem releasing the code, but there are a few technical constraints. - This is very much a test jig. For example, it uses psql via a pipe to do all database access. That stuff is layered out, so it can easily be directed at a real postgres perl module, but we have some issues with perl modules so tend not to use them, at least in early development. I would expect it to start groaning at around 100 calls/minute. We're in a beta test at the moment and will be in production within a month. When our call volume increases, we will certainly recode this in C. However, using direct database access from perl would probably give an 80% of the gains, so that might be the next step. - It depends on a special syslogd version. The change is simple -- the timestamp is written as "seconds since 1970" to msec precision instead of the human-readable representation. Unix time_t is simply more natural for this kind of work. I didn't attempt to layer the timestamp processing, but it only occurs in one or two places, so introducing mktime() and giving up on msecs would generalize this. I have a converted Linux syslogd.c. I'm pretty sure less than 10 lines changed. I know I converted a FreeBSD syslogd as well, but I can't find it. - The script uses the database to keep state. The first INVITE inserts the call detail and the call is active (no call_end time). The first BYE with matching call_id updates the call_end time. Heuristics are then applied to match each log entry from the gateway (cisco based) to the database entry. This allows detection of missed BYEs. The point is that the the database is integral in the matching algorithm. The side-benefit is that the database can be used to display active calls. The algorithm is dependent on efficient database indexing. - There is no particular dependency on database type except I do record endpoint IPs as Postgres "inet" types, but these are not searched so could as easily be "char" type. A "timestamp" type of some kind is pretty much crucial. So, I'm happy to push the code out to the group "as is". If nothing else, there are probably code fragments worthy of harvest. I can also put a bit of time into generalizing it a little before making it available. Opinions?

[Serusers] Accounting Script

Hi, Has anybody developed some sort of crude accounting script for SER that would match all BYEs with their respective INVITEs in the syslog file and say how many seconds each call lasted? Thanks, Ricardo

[Serusers] What has changed ???
by Stephan Reiff-Marganiec 26 Mar '03

26 Mar '03

I just updated ser from cvs and encounter the problem that ser will no longer start. I have my own module and a function (exec_pol) in that is started from ser.cfg in the route block. This used to work fine, but since the latest update from ser, ser just terminates saying "Parse Error: Command cannot be used in the block". I got this message after make all, make install and trying to start ser. I then realised that my module was not compiled anew because the find_export function now has more arguments (the NO_SCRIPT on, which it didn't need before). Having fixed this, things compile fine, but the error persists and I cannot start ser. Have I overseen an important change?? thanks, Stephan -- Dr Stephan Reiff-Marganiec Research Fellow Department of Computing Science; University of Stirling email: srm(a)cs.stir.ac.uk tel: 01786 46 7448 -- The University of Stirling is a university established in Scotland by charter at Stirling, FK9 4LA.

This was a "trigger" to ask the questions. Yes, we use a dual Athlon CPU for performance measurements. On this HW ser with simple configuration is able to do ~ 5000 CPS.

Am I right? > No, there is no HW manufacturer limitation. HW configuration really depends a lot on the test scenarios. If you are going to have many concurrent transactions, you will need at least 4 kB of memory per transaction. So if you know duration of the transactions you can easily calculate how fast you will run out of memory. If you are going to use user location and will have many users registered simultaneously, you will need some additional memory for user location records (~2kB per record). Our tests showed that usually memory is the bottleneck. The more memory you have the longer your tests can run. > So what about a dual CPU above? That's a machine we use for testing. Could you, please, provide us with more information regarding the testing ? We are also interested in such testing (especially if you can generate really high number of CPS or messages per second). Maybe we could provide you with some ser optimizations so both sides could benefit from it. Jan.
