Cribl LogStream supports forwarding of SNMP Traps out.

Configuring Cribl LogStream to Forward to SNMP Traps

In the QuickConnect UI: Click + Add beside Destinations. From the resulting drawer's tiles, select SNMP Trap. Next, click either + Add New or (if displayed) Select Existing. The resulting drawer will provide the following options and fields.

Or, in the Data Routes UI: From the top nav of a LogStream instance or Group, select Data > Destinations. From the resulting page's tiles or the Destinations left nav, select SNMP Trap. Next, click + Add New to open a New Destination modal that provides the following options and fields.

General Settings

Output ID: Enter a unique name to identify this SNMP Trap definition.

SNMP Trap destinations: One or more SNMP destinations to forward traps to.

  • Address: Destination host.
  • Port: Destination port. Defaults to 162.

Processing Settings


Pipeline: Pipeline to process data before sending the data out using this output.

System fields: A list of fields to automatically add to events that use this output. By default, includes cribl_pipe (identifying the LogStream Pipeline that processed the event). Supports wildcards. Other options include:

  • cribl_host – LogStream Node that processed the event.
  • cribl_wp – LogStream Worker Process that processed the event.
  • cribl_input – LogStream Source that processed the event.
  • cribl_output – LogStream Destination that processed the event.

Advanced Settings

Environment: If you're using GitOps, optionally use this field to specify a single Git branch on which to enable this configuration. If empty, the config will be enabled everywhere.

Considerations for Working with SNMP Traps Data

  • It's possible to work with SNMP metadata (i.e., we'll decode the packet). Options include dropping, routing, etc. However, packets cannot be modified and sent to another SNMP Destination.

  • SNMP packets can be forwarded to non-SNMP Destinations (e.g., Splunk, Syslog, S3, etc.).

  • SNMP packets can be forwarded to other SNMP Destinations. However, the contents of the incoming packet cannot be modified – i.e., we'll forward the packets verbatim as they came in.

  • Non-SNMP input data cannot be sent to SNMP Destinations.
