Add an entry to /etc/nf to rotate the logfiles:.

Make sure configuration directives land in /usr/local/etc/snmp/nf.

# Permit SNMP-monitored machines to snmptrap to us

In /etc/rc.conf, snmptrapd_enable="YES".

I couldn't make Net-SNMP 5.4.2.1 snmptrapd work properly on a FreeBSD system, so this section does not describe our current setup.

the-who:/etc/snmp/ is the Perl script that snmptrapd calls to email trap messages to cse-staff.

Perl NetSNMP::TrapReceiver::register("all", \&my_receiver) nf contains a reference to the NetSNMP embedded Perl features:

the-who:/etc/snmp/nf must be properly configured and snmptrapd must be running.

In nf, the informsink and/or trap2sink tokens must be assigned the value of our trap receiver,. Look for nf in /etc/snmp/ on Linux systems and in /usr/local/etc/snmp/ on FreeBSD systems.

Each CSE SNMP-monitored host must run Net-SNMP snmpd with a customized nf.

In CSE, we use Net-SNMP snmptrapd to receive notifications about renewable resource capacities on our monitored servers.
