Splunk Stream

Installation and Configuration Manual

This documentation does not apply to the most recent version of Splunk Stream. For documentation on the most recent version, go to the latest release.

Configure universal forwarder for Splunk_TA_stream

Send data to _internal index

Splunk Stream automatically configures universal forwarders to send data from Splunk_TA_stream to your _internal index over the Wire Data modular input at installation time. No additional universal forwarder configuration is required.

Manage Splunk_TA_stream stats data

Splunk_TA_stream (Stream forwarder) sends operational statistics and log data to _internal index. Splunk App for Stream uses this data to populate built-in dashboards, including the Stream Estimate dashboard.

There are three event types that Splunk_TA_stream sends to _internalindex:

  • stream:stats
  • stream:log
  • streamfwd*

The streamfwd* event type comes from the stream forwarder's local log file. The forwarder monitors that log file along with other files in the $SPLUNK_HOME/var/log/splunk/ directory. Though it is useful for troubleshooting locally, the data that streamfwd* contains is the same as the data that stream:log contains. Therefore, you can safely blacklist the streamfwd* event type to avoid indexing duplicate data.

For more information, see Include or exclude specific incoming data in the Getting Data In manual.

Modify universal forwarder data limits

By default, the Splunk universal forwarder sends a maximum of 256 Kbps of data to indexers. Depending on your streamfwd configuration, your deployment might generate more data than this.

To modify or remove the default universal forwarder limit:

1. Edit $SPLUNK_HOME/etc/apps/SplunkUniversalForwarder/local/limits.conf.

2. Modify the [thruput] stanza. For example:

maxKBps = 0
