Which component of Splunk uses port 8065 by default?

The component of Splunk that uses port 8065 by default is the Splunk Web app-server proxy. This is essential because it acts as an intermediary for web application requests, ensuring that incoming traffic is properly routed to the correct services within Splunk. The default configuration utilizes this port to serve user requests, handle data presentation, and manage user interactions with the application.

Understanding the role of the Splunk Web app-server proxy is crucial for troubleshooting and configuring your Splunk environment, as this component directly influences how users experience the web interface. It is important to recognize the distinction between this component and others, like the KV Store, which has its own specific ports and purposes, as well as splunkd, which generally runs on port 8089 and serves as the main Splunk backend service. By recognizing the specific functions of each component and their default ports, you can better manage and troubleshoot your Splunk installation.
