SNMP monitoring using getif and nagios

I use getif. a free Windows GUI-based network tool written by Philippe Simonet, to make a quick query of SNMP values from SNMP informant. You may download getif here.

Once installed, place the downloaded MIBs of SNMP-Informant under the Mibs sub-directory of GETIF. Here's a screenshot of getif in action:

For continuous monitoring of servers and networks, I use nagios to regularly poll environmental and performance statistics. The results can be graphed for better visualization and reporting.

Here are the pertinent nagios service and command configuration entries..

define service{
hostgroup_name windows
service_description mb-temp
check_command check_mbtemp!40!42
use template-service

define command{
command_name check_mbtemp
command_line $USER1$/check_snmp -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -o . -l 'MB temp' -u 'Celsius (Warn=$ARG1$ Crit=$ARG2$)'
