FreeBSD SNMP Monitoring using bsnmp
FreeBSD ships with a minimal bsnmpd(1) in the base OS which is tightly coupled with the OS subsystems like netgraph(3) and pf(4) which is really. This is very different from net-snmp which is a beast of its own.

Configuration
rc.conf.local
bsnmpd_enable="YES"
/etc/snmpd.config
# # Set some common variables # location := "Bangalore, India" contact := "mail@shankerbalan.net" system := 1 # FreeBSD traphost := localhost trapport := 162
/etc/hosts.allow
ACLs are managed using tcpwrappers
snmpd: 127.0.0.0/255.255.255.0 : allow
