Splunk HEC

Overview​

info

The Splunk output is currently a technology preview. The design and implementation are less mature than stable features and subject to change.

The Splunk HEC output can be used to send records to Splunk Enterprise or Splunk Cloud Platform via the HTTP Event Collector.

EF_FLOW_OUTPUT_SPLUNK_HEC_ENABLE​

Specifies whether the Splunk output is enabled.

  • Valid Values
    • true, false
  • Default
    • false

EF_FLOW_OUTPUT_SPLUNK_HEC_CIM_ENABLE​

Specifies whether the data will be sent using the Splunk Common Information Model (CIM).

  • Valid Values
    • true, false
  • Default
    • false

  • Default
    • 127.0.0.1:8088

EF_FLOW_OUTPUT_SPLUNK_HEC_TOKEN​

  • Default
    • ''

EF_FLOW_OUTPUT_SPLUNK_HEC_BATCH_DEADLINE​

The maximum time, in milliseconds, to wait for a batch of records to fill before being sent to Splunk.

  • Default
    • 2000

EF_FLOW_OUTPUT_SPLUNK_HEC_BATCH_MAX_BYTES​

The maximum size, in bytes, for a batch of records being sent to Splunk.

  • Default
    • 8388608

EF_FLOW_OUTPUT_SPLUNK_HEC_TLS_ENABLE​

This setting is used to enable/disable TLS connections to Splunk.

  • Valid Values
    • true, false
  • Default
    • false

EF_FLOW_OUTPUT_SPLUNK_HEC_TLS_SKIP_VERIFICATION​

This setting is used to enable/disable TLS verification of the Splunk server to which the output is attempting to connect.

    • true, false
  • Default
    • false

EF_FLOW_OUTPUT_SPLUNK_HEC_TLS_CA_CERT_FILEPATH​

The path to the Certificate Authority (CA) certificate to use for verification of the Splunk server to which the output is attempting to connect.

EF_FLOW_OUTPUT_SPLUNK_HEC_DROP_FIELDS​

This setting allows for a comma-separated list of fields that are to be removed from all records.

note

    • any field names related to the enabled schema, comma-separated
  • Example
    • flow.export.sysuptime,flow.export.version.ver,flow.start.sysuptime,flow.end.sysuptime,flow.seq_num
  • Default
    • ''
