I can’t get metrics with the plugin mackerel-plugin-snmp

Most malfunctions regarding the plugin mackerel-plugin-snmp are related to the following causes.

  • Not specifying the correct OID in the plugin options.
    • The plugin retrieves the object value of the OID specified by the SNMP Get Request. An OID with a subordinate tree can not be specified.
    • Use the snmpget command to check the plugin OID. Specify the target OID and check that the object value is returned.
    • The snmpwalk command returns a value even if you specify an OID with a subordinate tree. Be sure to use the snmpget command to confirm the OID to specify in the plugin.
  • Not specifying enough metric options
    • Metrics such as the OID must be specified in a format separated by halfwidth colons like this example: OID:NAME[:DIFF?][:STACK?]. The meaning of each part follows below.
Item Configuration Value Required
OID OID（Only MIBs with numerical reference values are supported Y
NAME The metric label displayed on the graph Y
DIFF Whether to calculate with a counter value (0 or 1) N
STACK Whether to display metrics stacked (0 or 1) N
    • Please make sure that NAME is specified as this is often not the case.
