Nagios Support Forum

Posted: **Mon Nov 03, 2014 10:39 am**

Hi

I have configure nagios core 4.0.7 with nrpe and its working perfectly fine and now I want extend nagios capability to monitor my SNMP device like switch router and ESXi host.

To that I have installed below RPM.

Code: Select all

[root@sov-srv-negios01 snmptt]# rpm -qa |grep snmp
net-snmp-utils-5.5-50.el6_6.1.x86_64
net-snmp-libs-5.5-50.el6_6.1.x86_64
net-snmp-devel-5.5-50.el6_6.1.x86_64
snmptt-1.4-0.9.beta2.el6.noarch
net-snmp-perl-5.5-50.el6_6.1.x86_64
net-snmp-5.5-50.el6_6.1.x86_64

I have configure SNMP TRAP daemon and my snmptrapd.conf file look like this

Code: Select all

[root@sov-srv-negios01 snmp]# more snmptrapd.conf

#
# No traps are handled by default, you must edit this file!
#
# authCommunity   log,execute,net public
logoption f /var/log/snmptrap.log
disableAuthorization yes
traphandle default /usr/sbin/snmptthandler
#traphandle default /usr/sbin/snmptt
createUser -e 8000000001020304 arqadmin SHA mypassword AES
authuser log arqadmin

After this I have configured SNMPTT daemon and i have attached my snmp.ini file

I have convert VMware MIBS by below command

Code: Select all

# for i in `ls -lrt |awk '{print $9}'`; do snmpttconvertmib --in=$i --out=/etc/snmp/snmptt.conf.vmware --exec='/usr/local/nagios/libexec/eventhandlers/submit_check_result $r TRAP 2 '; done

I have also attched my snmptt.con.vmware file

I have installed NSTI package also and all this work but I am not able get snmptt logs in correct format.

When I am poweron/off VM in ESXi host I am getting below messages in my snmptt.log file

snmptt logs

Hi,

Maybe a few things that might help:

You could simplify the /etc/snmp/snmptrapd.conf file:

Code: Select all

authCommunity log,execute,net public
traphandle default /usr/sbin/snmptt

This means that snmptraps with a community 'public' are processed.

I noticed a vmwVmPoweredOn creates a critical snmptrap. I'm not sure if that is what you want, but that should be no problem.

My /etc/snmp/snmptt.ini file looks like this (without comments):

Make sure you add your own snmptt.conf file(s)

The snmptrapd should be started with the following options (so it does not try to translate itself):

Code: Select all

OPTIONS="-Lsd -p /var/run/snmptrapd.pid -m ALL -On"

Now you should have some different log files. First of all you should be able to your snmptt log files in /var/log/snmptt/ and it should also give you the default snmptrap in your syslog file.

Just for my curiosity, what distribution are you using?

Thanks for the input Rob, some good points there! It appears that you presently have snmptrapd logging to an snmptt.log file and snmptt logs known traps to a file named the same, but in a different location. It is very confusing to try and understand which file you are actually referencing. However one thing I would note is that snmptt's snmptt.log MIGHT have the exec information in it for you, and a debug file definitely would. Anything from snmptrapd most definitely would not have the information you are looking for as it never handles exec lines of any sort. Could you run us through what you feel should be happening one more time with the snmptrapd file that you have named snmptt.log renamed for explanation purposes to snmptrapd.log, or append the full path so we can't get confused?

I had to bribe Rob with some beer to make him tell me all his SNMP secrets! He knows his stuff

Bribe Rob with beer? Isn't that like saying you had to bribe a fish with water?

If that was case, wouldn't alcoholics be a protected class?
