SNMP on OpenSolaris

SNMP is not installed by default on Open Solaris but really easy to set up. You don’t need to compile it from source as some would suggest.

All you’ll need is to install the SUNWsmmgr package.
pkg install SUNWsmmgr
All of the config files, including snmpd.conf are in /etc/sma/snmp.

The service to enable snmp is called sma.
svcadm enable svc:/application/management/sma:default

To install utilities like snmpwalk and snmpget, you can install the SUNWsmcmd package.
