Hi friends,
I am new to snmp and after some readings I have 2 questions:-
1) Does net-snmp AUTOMATICALLY sends trap when we configure agent's
snmpd.conf file with directives like trapsink, monitor, etc. for inbuilt
OIDs like cpu and disk??
I am asking because I am trying to send a trap when cpu goes beyond 90%. My
agent and master are on the same linux box.
My snmptrad.conf file:-
authCommunity log aaa
authCommunity log public
My snmpd.conf file (removing extra comment lines):-
master agentx com2sec notConfigUser default public
group notConfigGroup v1 notConfigUser group
notConfigGroup v2c notConfigUser
view systemview included .1.3.6.1.2.1.1 view systemview
included .1.3.6.1.2.1.25.1.1 view all included .1 view mib2 included
.iso.org.dod.internet.mgmt.mib-2 fc
access notConfigGroup "" any noauth exact systemview none none
createUser internalMonitoringName SHA mysecretpassword AES rouser
internalMonitoringName iquerySecName internalMonitoringName
com2sec local localhost aaa
com2sec net-27 x.x.x.x/8 aaa
com2sec net-46 x.x.x.x/24 aaa # x.x.x.x is some real IP in my network
com2sec net-60 x.x.x.x/24 aaa
com2sec net-10 x.x.x.x/16 aaa
group MyRWGroup any local
group MyROGroup any net-27
group MyROGroup any net-46
group MyROGroup any net-60
group MyROGroup any net-10
access MyROGroup "" any noauth 0 all none none
access MyRWGroup "" any noauth 0 all mib2 mib2
syslocation "Somewhere in testlab"
syscontact Root root@localhost
dontLogTCPWrappersConnects yes
trap2sink localhost aaa
monitor -r 30 machineTooBusy hrProcessorLoad > 90
When I run some process to increase cpu load, the cpu load goes beyond 90%
(I can see that in top command) but I can't see the trap message in
/var/log/messages.
What I am doing wrong here?
2) Also, my next question is, if I have a custom MIB file for which I have
wrtten an agent, Can I add the variable/OID from that custom MIB with
"monitor" directive in snmpd.conf file to send trap AUTOMATICALLY? OR I
must send trap from within my agent???
Please help on my confusion...
