EV Observe - Use GLOBAL-SNMP-OID Service Template
The GLOBAL-SNMP-OID service template uses the generic plugin, check_snmp_oid, to collect information via SNMP, query a host using its OID and compare its value with warning and critical thresholds.
Performance data can be generated to create a chart.
See the service template catalog
Example
Monitoring a new server
1. Search for the server OID in the supplier's management information base (MIB)
==> OID: 1.2.9.64.8.3
2. Analyze the server OID containing properties specific to the host
==> Retrieve information on disk space usage
Notes
- The service template is used to query the OID of an MIB which will return a numerical value. It can be used for monitoring any element referenced in the host MIB.
Best Practice
- To display two values or perform mathematical operations using multiple OIDs, you should use the Global-SNMP-Operation service template. This service template will perform one or two mathematical operations using multiple OIDs and return one or two results. A notification will be triggered when the result of the first calculation exceeds a specified threshold.
