HTTP Out now allows the Universal Forwarder to make use of a standard protocol and port (443), which is generally open and trusted, for outgoing traffic. Typically in these situations it would require more complex network configuration, or network traffic exceptions, to support traditional S2S for the connection from the Universal Forwarder to the Indexers. Where the new HTTP Out feature is especially useful is in scenarios such as collecting data from systems in an edge location or collecting data from a roaming user’s device. To date, this is a practice which has not been recommended, or supported, for traditional S2S based data forwarding. Additionally, this now enables the use of a 3rd party load-balancer between Universal Forwarders and Splunk Receivers. What this feature does is effectively encapsulates the S2S message within a HTTP payload. Using the ‘HTTP Out Sender for Universal Forwarder’ it can now send data to a Splunk Indexer using HTTP. Traditionally, a Splunk Universal Forwarder uses the proprietary Splunk-to-Splunk (S2S) protocol for communicating with the Indexers. In $SPLUNK_HOME/etc/apps/SplunkUniversalForwarder/default/inputs.The release of version 8.1.0 of the Splunk Universal Forwarder introduced a brand new feature to support sending data over HTTP. ![]() To mitigate this, reduce duplication so that all three of the following stanzas do not use wildcards: If not monitored appropriately, the additional data could cause your hard disks to fill up and Splunk to stop working. This could cause data to duplicate multiple times, which could increase the amount of disk space used and add additional work in the cluster. When you set up multiple output groups in multiple stanzas using wildcards, the same data could be sent to all of the output groups. ![]() You can solve this by shortening your data ingestion intervals using the universal forwarder user interface, or nf. The most common cause of ingestion lagging is that you are taking in too much data from one sourcetype, which is blocking data from other sourcetypes.
