rsyslog: do not collect logs from some application

Tuesday, June 26th, 2018

If there’s no settings in the application itself, you can configure rsyslog not to write apps logs.

CentOS 6.6, rsyslog 5.8.10-10.el6_6:
Asterisk is configured to write logs to remote syslog server (syslog02.core) but still writes not only there but also locally.
To prevent this:
create ‘/etc/rsyslog.d/10-asterisk.conf’ with lines

:syslogtag, contains, "asterisk" @syslog02.core
& stop

Debian 9.4 Stretch, rsyslog 8.24.0-1:
Asterisk is nt configured to write to remote syslog, but also writes everything to local rsyslog.
Create ‘/etc/rsyslog.d/10-asterisk.conf’:

if $programname == "asterisk" then {
stop
}
