[SR-Users] how to prevent the log_prefix in syslog acc cdrs?

[Karsten Horsmann]

Hi List,

i thought there could be a solution to disable the log_prefix for acc
module - but i didn't found it. Is there a solution to supress log_prefix
for acc like acc_json did that?

I use kamailio 5.5.2 with that settings:

log_name="kamailio"
log_facility=LOG_LOCAL4
log_prefix="{$hdr(CSeq) $ci} "

the acc module then logs the "log_prefix" - plus some module/function stuff:

INFO: {1 INVITE SDkk50d01-1f7cc956b0b908e42d284189a11b44e7-ct46om0050} acc
[acc.c:285]: acc_log_request(): ACC: transaction answered:

The acc_json module is able to log acc without log_prefix:

And just for the records - how to get rid off the rsyslog prefix time/date
stuff:

# /etc/rsyslog.d/kamailio.conf
# drop :msg from rtpengine with "timer run time" - debugging only:
:msg, contains, "timer run time" ~
# Template only msg:
$template myFormat,"%msg%\n"
# log only to local* and NOT to /var/log/messages
local6.*;local6.!=info
 -/var/log/platform/voip/kamailio/rtpengine.log
local6.*                                                stop
local5.*
 -/var/log/platform/voip/kamailio/rtpengine-cdr.log; myFormat
local5.*                                                stop
local4.*
 -/var/log/platform/voip/kamailio/kamailio.log
local4.*                                                stop
local2.*
 -/var/log/platform/voip/kamailio/kamailio-cdr.log; myFormat
local2.*                                                stop
local1.*
 -/var/log/platform/voip/kamailio/kamailio-cdr-json.log; myFormat
local1.*                                                stop
