Does Splunk use TCP or UDP?
Splunk Enterprise supports monitoring over UDP, but you should use TCP to send network data instead whenever possible.

Splunk Enterprise supports monitoring over UDP, but you should use TCP to send network data instead whenever possible. UDP is not desirable as a transport because, among other reasons, it does not guarantee delivery of network packets.Click to see full answer. Considering this, what protocol does Splunk use?Splunk components communicate with each other using TCP and UDP network protocols. A firewall that has not been configured to allow these ports open can block communication between the Splunk instances.Secondly, what port does Splunk forwarder use? Splunk Universal Forwarder includes a management service that is listening on TCP port 8089 and is used for managing the forwarder. By default it accepts remote connections, but doesn’t allow remote connections with default credentials ( admin/changeme ). In this way, what ports does Splunk use? This is a diagram of Splunk components and network ports that are commonly used in a Splunk Enterprise environment. Firewall rules often need to be updated to allow communication on ports 8000, 8089, 9997, 514 and others. Since splunk 6.2 also port 8191 is used for the kvstore.Does syslog use TCP or UDP?As stated previously the default port of syslog is UDP 514 as we know UDP is unreliable protocol according to TCP. syslog can be used for important security logs which can not tolerate log loss. We can use TCP which is far more reliable than UDP with the same port number 514.
