not that I expect this to fix it (this isn't something I've seen as a known bug), but could you please confirm that this still happens on the current version of rsyslog?

Subject: Re: [rsyslog] Reducing selector effect in RainerScript

I've stripped down my config to just this rule, and tried with and without the 
stop directive - after restarting rsyslogd, of course - no change.

Also happens on the rsyslogd versions delivered with Solaris 11.4, RHEL 7.x and 
RHEL 8.x, which all hover around the 8.210x version

Generally, your config should work the way you indended. It's hard to
say however if other entries in your config don't cause any side effects.

You could add a "stop" directive to make sure that events matching your
selector won't be processed further. Like:

*.debug;local6.err {
   action( type="omfile" file="/what/ever/file")
   stop
}

I'm porting some configurations from syslog to rsyslog, and seeing some
unexpected selector behavior in rsyslog 8.2104

After reading the selector examples from the configuration portion of the
rsyslog manual, I'm either misunderstanding how this is supposed to work, or
there's a long standing issue here.

So, the original selector looks like this:

*.debug;local6.err

The intent is to log all facilities at debug or higher, except for local6,
which should only log at err or higher.  So I end up with a RainerScript block
like so:

*.debug;local6.err {
    action( type="omfile" file="/what/ever/file")
}

But, I start to see messages at local6.info show up in the file, surprisingly.

To get the desired end effect, I end up having to craft the selector like so
(which only works because only local6.info is chatty, nothing higher than
that), which surprises me:

*.debug;local6.err;local6.!=info

So, am I simply doing this wrong/misunderstanding how selectors work, or is
there something odd going on?
