I'm having an issue on FreeBSD 14.0 (pfSense 2.7.2) where I want to filter out some unwanted syslog messages. Long story short, I think there's a bug in the Prometheus Node Exporter package, which gives the following unwanted syslog messages each minute:
For the time being, I just want to filter out those messages. I've really done thorough research, and read a number of forum posts here and other places, but I haven't yet found an answer that worked for me (including this one, which I can't get to work).
I initially tried to make a file
But this doesn't work. I also tried:
Which didn't work either.
Can any one point me to a reference on how to filter out syslog messages on FreeBSD, and what the exact syntax is? I would like to be able to understand the official documentation for this with examples, but I don't think it's very clear on suppressing (or redirecting) messages - or at least I can't get the examples to work in my case.
I tried asking on the pfSense forums a week ago, but it seems no one there knows (or wants to share) how to suppress log messages.
Thank you.

01-node-exporter.conf and put it inside /var/etc/syslog.d/ with the following contents:

:msg, contains, "collector failed" ~Which didn't work either.
