Thanks Daniel for the explaination !   I found something in a Kamailio sample script that does what I want to do, e.g. :   #!ifdef WITH_DEBUG_SCRIPT                                xlog("L_INFO", "Request-URI: $ru\n"); #!endif     This allows me to log « debug » information from the script as INFO when the flag WITH_DEBUG_SCRIPT is set. It’s a bit clumsy but it works. :)   (I don’t know if having the xlog exported functions changed so they go look at the configuration of the debugger module would be complicated, or even feasible – would be nice though ! ^^)     Cheers! Nicolas.   *De :*Daniel-Constantin Mierla &lt;miconda(a)gmail.com&gt; *Envoyé :* jeudi 31 décembre 2020 14:04 Hello, the log messages that have "script" in the prefix are from kamailio.cfg routing blocks, not from the C code. You can remove, change their log level, ... by editing the kamailio.cfg. The script log messages are printed by the functions exported from xlog module.

I’ve seen that the « debugger » module allows to do that with modules or « core » :   https://kamailio.org/docs/modules/5.4.x/modules/debugger.html#dbg.p.mod_lev… <https://kamailio.org/docs/modules/5.4.x/modules/debugger.html#dbg.p.mod_level>     So I’ve tried to do :   modparam("debugger", "mod_level_mode", 1) modparam("debugger", "mod_hash_size", 5) modparam("debugger", "mod_level", "my_module=3") // this works modparam("debugger", "mod_level", "core=3") // also works modparam("debugger", "mod_level", "script=3") // nope…     But it doesn’t seem to work for « script »… :/     Regards, Nicolas.   This message contains information that may be privileged or confidential and is the property of the Capgemini Group.
