The module msgsniff is for you to probe all the messages being generated and, or received by Yate.
This module should be used on development systems only and should be disable on production systems.
The loading of msgsniff.yate is controlled by yate.conf like any other module.
The initial activation is controlled by msgsniff in [general] of same yate.conf file. The default status is off as it would flood the logs and hit the performance.

Enable msgsniff in Yate's main configuration file
The sniffer will dump the Yate messages to output or log file.
All Yate's messages will be seen and their parameters.
- It can be enabled in yate.conf:
[general] msgsniff=yes modload=no ;Don't forget to load the sniffer module if modload parameter value is 'no'. [modules] ;for debugging yate rmanager.yate=yes msgsniff.yate=yes
After enable the sniffer, start Yate with logging:
./run -vvvvv -l yate.log
Enable / Disable sniffer in telnet
The module must be loaded so that you can use this commands from telnet:
telnet 0 5038 debug on color on sniffer on
and disabled with:
sniffer off
Sniffer on will dump the message and his parameters, each on a separated line.
With sniffer the messages will be seen twice:
- - once when they are emitted
- - once when they are handled (or not)
If you need the output to be parsed by a machine you can use in telnet:
machine on
This will dump the messages and their parameters in a single line using ':' as a separator.
To disable it:
machine off
Apply filter messages with sniffer
- Apply filter by specifying regex to match in telnet:
sniffer filter ^\(chan\.\|engine\.halt$\)
sniffer on filter chan.control\|gtp.*
sniffer on filter call.execute
- or in yate.conf:
[default] ; filtersniff: regexp: Default filter to apply to message sniffer at initialization ; If empty it will match all messages except engine.timer which is never displayed ; Example for a filter matching all chan.Anything messages and engine.halt: filtersniff=^\(chan\.\|engine\.halt$\)
Example
- Sniffer output example:
telnet 0 5038 Trying 0.0.0.0... Connected to 0 (0.0.0.0). Escape character is '^]'.
