Here's the sort of thing you might do to set up SNMP support on your
system, assuming that you have net-snmp installed in the normal
locations for something like RedHat Linux.
0. Edit the example GNUSTEP-MIB.txt to contain your own organisation's
Private Enterprise Number. This stage is optional, you may use the
MIB 'as-is' with the GNUstep PEN if you wish. You only need to use
an edited version if your organisation wishes to use its own MIB
with additional features not in the GNUstep one.
If you are using your own MIB, replace all ocurrances below of
GNUSTEP-MIB.txt with the name of your own MIB file.
1. install GNUSTEP-MIB.txt in /usr/share/snmp/mibs
2. edit '/etc/sysconfig/snmpd.options' to contain:
OPTIONS="$OPTIONS -Dgnustep -Lf /var/log/snmpd"
export OPTIONS
so that any debug for the gnustep module would be logged
in /var/log/snmpd
3. edit '/etc/sysconfig/snmptrapd.options' to contain:
OPTIONS="$OPTIONS -Dgnustep -Lf /var/log/snmptrapd"
export OPTIONS
so that any debug for the gnustep module would be logged
in /var/log/snmptrapd
4. edit /etc/snmp/snmpd.conf to get it to send traps to snmptrapd ...
rwcommunity public
trap2sink localhost public
and to accept agentx connections via tcp ...
agentxsocket tcp:localhost:705
master agentx
having the snmp daemon listening on port 705 for agentx connections is
essential for the default setup of alarming, but you can use a different
host and port if you wish (see the EcAlarmSinkSNMP initialisation for
details).
5. restart with '/sbin/service snmpd restart'
If you are starting snmp for the first time on a RedHat system then:
# /sbin/chkconfig snmpd on
# /sbin/service snmpd start
should enable the snmp service and then start it.
6. build/install/run the Control server
7. test with snmpwalk ...
To look at EVERYTHING:
snmpwalk -v 1 -c public localhost GNUSTEP-MIB::gnustep
To look at the current alarms table:
snmpwalk -v 1 -c public localhost GNUSTEP-MIB::gnustep.alarms.alarmsTable
To look at the current alarms table in a tabular format (rows of columns) which will be far too wide to view in a normal terminal window:
snmptable -v 1 -c public localhost GNUSTEP-MIB::gnustep.alarms.alarmsTable
To look at the managed objects table:
snmpwalk -v 1 -c public localhost GNUSTEP-MIB::gnustep.objects
You should be able to get the heartbeat poll interval with:
snmpget -v 1 -c public localhost GNUSTEP-MIB::pollHeartBeat.0
You should be able to set the heartbeat poll interval to two minutes with
snmpset -v 1 -c public localhost GNUSTEP-MIB::pollHeartBeat.0 i 2
You should be able to set the resync flag interval with
snmpset -v 1 -c public localhost GNUSTEP-MIB::resyncFlag.0 i 1
and set it back to normal with
snmpset -v 1 -c public localhost GNUSTEP-MIB::resyncFlag.0 i 0
