Read snmp trap messages as events

Resulting @message looks like :

  #<SNMP::SNMPv1_Trap:0x6f1a7a4 @varbind_list=[#<SNMP::VarBind:0x2d7bcd8f @value="teststring",
  @name=[]>], @timestamp=#<SNMP::TimeTicks:0x1af47e9d @value=55>, @generic_trap=6,
  @enterprise=[], @source_ip="", @agent_addr=#<SNMP::IpAddress:0x29a4833e @value="\xC0\xC1\xC2\xC3">,



This plugin supports the following configuration options:

Required configuration options:

snmptrap {

Available configuration options:




  • Value type is hash
  • Default value is {}

Add a field to an event


  • Value type is codec
  • Default value is "plain"

The codec used for input data. Input codecs are a convenient method for decoding your data before it enters the input, without needing a separate filter in your Logstash pipeline.


  • Value type is array
  • Default value is "public"

SNMP Community String to listen for.


  • Value type is boolean
  • Default value is true

Disable or enable metric logging for this specific plugin instance by default we record all the metrics we can, but you can disable metrics collection for a specific plugin.


  • Value type is string
  • Default value is ""

The address to listen on


  • Value type is string
  • There is no default value for this setting.

Add a unique ID to the plugin configuration. If no ID is specified, Logstash will generate one. It is strongly recommended to set this ID in your configuration. This is particularly useful when you have two or more plugins of the same type, for example, if you have 2 grok filters. Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

output {
 stdout {
   id => "my_plugin_id"


  • Value type is number
  • Default value is 1062

The port to listen on. Remember that ports less than 1024 (privileged ports) may require root to use. hence the default of 1062.


  • Value type is array
  • There is no default value for this setting.

Add any number of arbitrary tags to your event.

This can help with processing later.


  • Value type is string
  • There is no default value for this setting.

This is the base class for Logstash inputs. Add a type field to all events handled by this input.

Types are used mainly for filter activation.

The type is stored as part of the event itself, so you can also use the type to search for it in Kibana.

If you try to set a type on an event that already has one (for example when you send an event from a shipper to an indexer) then a new input will not override the existing type. A type set at the shipper stays with that event for its life even when sent to another Logstash server.


  • Value type is string
  • There is no default value for this setting.
