The experimental config file is attached, which has all the A/B tests, with associated comments.
I didn't receive the intervening post wondering whether I had posted the config file somewhere, but I did post it at https://github.com/rsyslog/rsyslog/issues/4299, and it also can be accessed there. -ERB -----Original Message----- From: David Lang [mailto:[email protected]] Sent: Sunday, July 05, 2020 5:48 PM To: Eric Blomquist via rsyslog Cc: 'Rainer Gerhards'; Eric Blomquist Subject: Re: [rsyslog] imkmsg absent from 8.2006; How to get imuxsock to read kernel messages? please post your config David Lang On Sun, 5 Jul 2020, Eric Blomquist via rsyslog wrote: > Date: Sun, 5 Jul 2020 12:42:00 -0700 > From: Eric Blomquist via rsyslog <[email protected]> > To: 'Rainer Gerhards' <[email protected]>, > 'rsyslog-users' <[email protected]> > Cc: Eric Blomquist <[email protected]> > Subject: Re: [rsyslog] imkmsg absent from 8.2006; How to get imuxsock to read > kernel messages? > > Thanks for responding. > > Yes, of course. imklog was the first thing I tried, and it has been > configured to load throughout this process. > > In fact, I experimented with a great number of alternative configurations > before I thought to try substituting imkmsg for imklog, only to discover that > imkmsg was/is missing. > > No matter what we do, no rule in an imuxsock ruleset (even *.*) reads > iptables log messages. > > We know the messages exist, both from running dmesg and because standalone > rules (outside an imuxsock ruleset) read the messages. > > I experimented with all varieties of syntax, filter, filter text, operator, > and property.
