Using SNMP, this plugin allows you to:
– interrogate an OID.
– compare the value returned with warning and critical thresholds.
– choose the text to display along with the value.
– choose the values units.
– collect performance data to create a graph.
First, obtain the SNMP MIB for the device and consult it.
For example, according to the MIB of the new server, the disk space used is obtained with the OID: 188.8.131.52.8.3
Navigate to “Configuration” “Services” “List” and then “Add”.
Select the Service Template: GLOBAL-SNMP-OID and give the Service a name.
Configure the Template settings:
The resulting output text will look something like this: “Disk space used: GB value”
Deploy the Service to the host to be monitored.
Finally, reload the ServiceNav Box configuration.
The performance data is visible in the metrics section:
This Service Template is used to query the OID of a MIB that returns a numeric value.
It can be used to monitor any object (referenced in the MIB) of a device.
Sometimes it is necessary to display two values or to perform mathematical operations between several OIDs. In such a scenario, use the check_snmp_operation plugin instead.
