How to exclude the output of any program from syslog-ng?

Question

linux

Welcome all.
Neither in man'e, nor in Google did I find information on how to exclude any program from the exhaust.
For example: conky kicks amixer every second for volume level and this is reflected in the log.
Is it possible to filter or only to /dev/null (then there will be no output to conky) ?

Answer 1

Thank you all !
This helped:

Defaults logfile=/var/log/sudolog
Defaults:fil !syslog
Defaults:mumsic !syslog

Answer 2

Judging by the example of your log, you need to disable sudo logging (or move it to a separate file).
For example like this:

# sudo visudo /etc/sudoers
Defaults logfile=/var/log/sudolog
Defaults syslog=off

Try to make a rule:
destination devnull { file("/dev/null"); };
filter conky { program("conky"); };
log { source(src); filter(conky); destination(devnull); };
