Use a Splunk Universal Forwarder to securely send UDP (or TCP) data to Splunk.
With the StatsD Endpoint type, you can send metric data to a Splunk installation. In Splunk, you can use SSL to secure ports that are open for StatsD.
StatsD metrics are typically sent over UDP. By using UDP, the client sending metrics does not have to block as it would if using TCP. However, using TCP guarantees order and ensures no metrics are lost.
You can configure open UDP (or TCP) ports in Splunk to accept only connections from a certain hostname or IP address.
- Send the data to a Splunk Universal Forwarder.
- Have the forwarder communicate with the Splunk Indexer over SSL.
