Ah I see. I was referring to busybox. I don't have any experience with rsyslog or syslog-ng. Would you recommend one for a new user? I typically look at the system log via luci as I find it more convenient, not sure if one package or the other is more suitable for someone who uses luci more often.
EDIT: ended up using rsyslog via this post and was able to get the log filtered the way I like.
