SNMP Trap Input Plugin

The SNMP Trap plugin is a service input plugin that receives SNMP notifications (traps and inform requests).

Notifications are received on plain UDP. The port to listen is configurable.

OIDs can be resolved to strings using system MIB files. This is done in same way as the SNMP input plugin. See the section "MIB Lookups" in the SNMP README.md for details.

Configuration

# Snmp trap listener
[[inputs.snmp_trap]]
  ## Transport, local address, and port to listen on.  Transport must
  ## be "udp://".  Omit local address to listen on all interfaces.
  ##   example: "udp://127.0.0.1:1234"
  # service_address = udp://:162
  ## Timeout running snmptranslate command
  # timeout = "5s"

Metrics

• snmp_trap
  • tags:
    • source (string, IP address of trap source)
    • name (string, value from SNMPv2-MIB::snmpTrapOID.0 PDU)
    • mib (string, MIB from SNMPv2-MIB::snmpTrapOID.0 PDU)
    • oid (string, OID string from SNMPv2-MIB::snmpTrapOID.0 PDU)
    • version (string, "1" or "2c" or "3")
  • fields:
    • Fields are mapped from variables in the trap. Field names are the trap variable names after MIB lookup. Field values are trap variable values.
