How to prevent a particular application from writing to syslog?

Question

linux

Greetings, there is an ubuntu 14-04 server that acts as a software router, there is some application compiled from sources (coovachilli), I noticed that this application is decently shitting in syslog with system messages that are essentially garbage. And it turns out that the whole / var (80) gb is clogged overnight. Temporarily solved it with a log cleaning script once an hour. Also, the problem is that the rsyslog daemon loads the processor up to 60%. There are no logging directives in the application configs. I didn't find anything in rsyslog.d/ either. Question how it is possible to forbid record in syslog to separate application? THX.

Answer 1

Yes, that's just in rsyslog something easier than a steamed turnip. Add to rsyslog.conf:
and that's it, rsyslog will send all messages from the specified program to where the place never ends :)

Answer 2

As an option, disable the application to work with port UDP 514
Or delve into the rsyslog config and do not forget to use man
There is really little information on this topic.
