The most widely used SNMP versions are SNMP version 1 (SNMPv1) and SNMP version 2 (SNMPv2). SNMP version 3 (SNMPv3) includes important changes with respect to previous versions, especially in security issues; however, its acceptance has been very low due to some implementation problems and incompatibilities.
- If you’re using SNMPv1 or v2: Is the device configured with the correct community string in LogicMonitor (either at the global, group or device level)? If no community string is set, LogicMonitor defaults to using public. Note: Some Linux distributions significantly restrict which metrics are exposed if the community string is set to “public”. Therefore, we recommend you set your community string to something else. See the section below to verify that your device has the correct community string set.
- If you’re using SNMPv3: Is the device configured with the correct authpass, privpass and username (either at the global, group or device level)? See the section below to verify that your device has the correct v3 credentials set.
Can queries from the collector device reach the monitored device?
What is snmpwalk?
snmpwalk is the name given to an SNMP application that executes multiple GETNEXT requests automatically. The SNMP GETNEXT request is used to query a device and grab SNMP data from a device. The snmpwalk command is used because it allows the user to chain GETNEXT requests together without having to enter unique commands for each OID or node within a subtree.
