Internal support hints
Important note:
Following articles are designed to be used by internal support team. You can find hints usauseful but please use it at your own risk (use on testing servers first)
Testing regexp / country rules / billing
Regexp test
/usr/local/sbin/voipmonitor --config-file=/etc/voipmonitor-test.conf -k -v1 --test-regexp '^800880080[1-9][0-9][*]|80088008012345|'
Country assignment test
/usr/local/sbin/voipmonitor --config-file=/etc/voipmonitor-test.conf -k -v1 --find-country-for-ip=102.140.68.113 /usr/local/sbin/voipmonitor --config-file=/etc/voipmonitor-test.conf -k -v1 --find-country-for-number 0034*12345
pricing / billing test
voipmonitor --config-file=config/voipmonitor.conf -k -v1 --test-billing test_data/billing
Example of test_data/billing file
Columns order - calldate - connect_duration - caller - called - sipcallerip - sipcalledip - expected price operator - (voluntary option) - expected price customer - (voluntary option)

SCRIPTs for better run control
ALERTS
When alerts taking longer time to process then interval is schedulled it can cause out of memory or high load to CPU after some time because same alert is processed multipletimes for various time ranges. Following script allows manual run of disabled alert in GUI via crontab - its benefit is that it will run multiple alerts at same time unlike normal run where is processed one alert by one.
Follow this link script-for-multi-Instances-alerts-processing
Batch download for more then 1000CDRs
When you need to download lot of audio files - you use GUI->menu->cdr batch download,but it allows only 1000calls to process with one GUI's query.
Following script allows you to create audio from longer set of CDRs, also it process in multiple instances to get audio faster (beware of HDD IO/CPU) script-for-big-batchdownloads
RAM (alerts / dashboards cache)
When there is lot of CDRs then alerts or caching of dashboard data can take lot of RAM, folloowing script will control if some php thread will not consume over limit, when it does, its oom_adj_score is set to be killed first (prevent killing of voipmonitor sniffer od db when running on same server)
Follow link script-for-GUI-cron-control-oom
voipmonitor sniffer memory leaks detect and debug
When voipmonitor uses more and more RAM (RSS/VSZ stat in syslog) without processing more CALLs (regs/messages) following steps can tell you where the RAM ends (it can be leak or some thread overload)
compile je_malloc
Download jemalloc from https://github.com/jemalloc/jemalloc
./autogen.sh (requieres development tools Deb/ubu apt install build-essential, centos/rh yum groupinstall 'Development Tools') ./configure --enable-prof make make install
enable jemalloc for voipmonitor and compile it
./configure
edit config.h,to have there
#define HAVE_LIBTCMALLOC 0 #define HAVE_LIBJEMALLOC 1
edit Makefile and disable optimization
substitute there -O2 with -O0 (It is capital o followed by zero)
Finish compilation
make clean make -j8
enable X88 compatible sources and recompile
Copy sniffer sources with compiled binary to new location and recreate binary with -X88
cp -a /usr/src/voipmonitor-git /usr/src/sniffer-git-jemalloc-X88 ./voipmonitor -k -v1 -c -X88 #It will list of source files modification,then re-make make clean make
Modify init file or run sniffer manually with extra env arguments and parameters
edit /etc/init.d/voipmonitor
ARGS="-v 1,force_log_sqlq,memory_stat,memory_stat_ignore_limit=100000" #and in start section (2places) of a script LD_PRELOAD=/usr/local/lib/libjemalloc.so MALLOC_CONF='prof:true' /usr/src/sniffer-git-jemalloc-X88/voipmonitor --config-file $CONFIGFILE --pid-file $PIDFILE $ARGS
or run it from konsole / when sniffer service stopped
LD_PRELOAD=/usr/local/lib/libjemalloc.so MALLOC_CONF='prof:true' /usr/src/sniffer-git-jemalloc-X88/voipmonitor --config-file=/etc/voipmonitor.conf -v 1,force_log_sqlq,memory_stat_ex,memory_stat_ignore_limit=100000,heapsafe
Check results
in some interval you should check the results of memory usage with
