So I've made a little headway into this. Thought I would post an update as it
may help others in the future.
Starting off referencing this bug report:
https://sourceforge.net/p/net-snmp/bugs/2610/
I can confirm that only d,i,7,6 produce any output in the logs. All other
priorities do nothing.
I do not see any difference between LOG_INFO and LOG_DEBUG.
I mean LOG_DEBUG should be reporting all the steps.
With a really simple snmptrapd.conf file:
disableAuthorization yes
traphandle default /usr/sbin/snmptthandler
It should at least log that it's executing /usr/sbin/snmptthandler for the trap
received.
I've done a lot of troubleshooting of recent and it's clear that a lot is going
on with snmptrapd which would be very useful if reported in debug logging.
Does anyone else have the same feelings about this?

Subject: Clarification on logOption in snmptrapd.conf
Date: Wed, 25 Mar 2015 14:21:58 +1100
I've been playing with the logOption directive for snmptrapd.conf.
When I specify it this way:
logOption f /var/log/snmptrapd.log
I do get traps logged in this file.
However what level of logging is this? Is it just LOG_NOTICE?
Reading the MAN page:
http://www.net-snmp.org/docs/man/snmpcmd.html
Normal output is (or will be!) logged at a priority level of
LOG_NOTICE
But this text seems to follow after the uppercase F option which is for
specifying priorities.
"For
-LF
and
-LS
the priority specification comes before the file or facility token"
So I've tried this:
logOption F d /var/log/snmptrapd.log
or
logOption F 7 /var/log/snmptrapd.log
Which still logs in /var/log/messages.
logOption Fd /var/log/snmptrapd.log
or
logOption F7 /var/log/snmptrapd.log
or
logOption F 0-7 /var/log/snmptrapd.log
Which still logs in /var/log/messages.
logOption F d/var/log/snmptrapd.log
or
logOption F 7/var/log/snmptrapd.log
Which still logs in /var/log/messages.
logOption F pd /var/log/snmptrapd.log
or
logOption F p7 /var/log/snmptrapd.log
Results in "Starting snmptrapd: invalid priority: p"
logOption d F /var/log/snmptrapd.log
or
logOption 7 F /var/log/snmptrapd.log
Results in "Starting snmptrapd: Unknown logging option passed to -L: d." or
"Starting snmptrapd: Unknown logging option passed to -L: 7."
So I am pretty confused.
My goal is to have debug logging to a separate file.
I also want to be able to specify it in the snmptrapd.conf file.
Thanks in advance for all replies.
