First you will need to make sure SNMP is installed.<\/p>\n

apt-get install snmpd snmp snmp-mibs-downloader<\/pre>\n
You’ll need to configure a new snmpd.conf file with<\/p>\n
snmpconf<\/pre>\n
Run through the steps and when your done replace your current snmpd.conf file in \/etc\/snmp\/ with the new one.<\/p>\n
Now open up your new snmpd.conf file<\/p>\n
vi \/etc\/snmp\/snmpd.conf<\/pre>\n
and add the following to the bottom of the file.<\/p>\n
extend myshscript \/path\/to\/your.sh<\/pre>\n
Save and close the file and restart the snmpd service.<\/p>\n
service snmpd restart<\/pre>\n
Now we need to find the OID of our new data point.\u00a0 Do this by running<\/p>\n
snmpwalk -v2c -c public localhost .1.3.6.1.4.1.8072.1.3.2<\/pre>\n
It should display something similar to the following.<\/p>\n
root@localhost:\/etc\/snmp# snmpwalk -v2c -c public localhost .1.3.6.1.4.1.8072.1.3.2\r\niso.3.6.1.4.1.8072.1.3.2.1.0 = INTEGER: 1\r\niso.3.6.1.4.1.8072.1.3.2.2.1.2.4.118.111.108.116 = STRING: \"\/etc\/snmp\/volt.sh\"\r\niso.3.6.1.4.1.8072.1.3.2.3.1.4.4.118.111.108.116 = INTEGER: 0\r\niso.3.6.1.4.1.8072.1.3.2.4.1.2.4.118.111.108.116.1 = STRING: \"14.3\"\r\nroot@localhost:\/etc\/snmp#\r\n<\/pre>\n
The OID we are interested in is the one on the last line.\u00a0 If you run a snmpwalk command with the OID you should get your data point.<\/p>\n
root@localhost:\/etc\/snmp# snmpwalk -v2c -c public localhost 1.3.6.1.4.1.8072.1.3.2.4.1.2.4.118.111.108.116.1\r\niso.3.6.1.4.1.8072.1.3.2.4.1.2.4.118.111.108.116.1 = STRING: \"14.3\"\r\nroot@localhost:\/etc\/snmp#\r\n<\/pre>\n
All that’s left is to add the OID to your SNMP monitor.\u00a0 If You run into issues with your SNMP server not monitoring the OID, you might need do what I did in the above command, replace the beginning of the OID “iso.” with a “1”.<\/p>\n
