Splunk offers a wide variety of apps and add-ons that extend Splunk's capabilities. Apps simplify the process of getting data into Splunk. Instead of configuring inputs yourself for a particular environment or application, you can often find an app with the data inputs preconfigured. Download apps from Splunkbase.
Apps typically target specific data types and handle everything from configuring the inputs to generating useful views of the data. For example, there's a Windows app that provides pre-built data inputs, searches, reports, alerts, and dashboards for Windows server and desktop management. There's a *nix app that offers the same for Unix and Linux environments. There's a wide range of other apps that handle specific types of application data, such as the Splunk for Blue Coat ProxySGapp, the Splunk for F5 app, the Cisco Security Suite app, and the Splunk App for Websphere Application Server.
The Add Data landing page in Splunk Web is a good place to start. Its data input pages link directly to a number of the most popular apps. You can also go directly to Splunkbase to browse through the large and growing set of apps available for download. Check Splunkbase frequently; new apps are being added all the time.
Important: If Splunk Web is located behind a proxy server, you might have trouble accessing Splunkbase directly within Splunk. To solve this problem, you need to set the
http_proxy environment variable, as described in "Specify a proxy server" in the Admin manual.
For more information on apps in general, see the set of topics beginning with "What are apps and add-ons?" in the Admin manual. In particular, this topic tells you how to download and install apps: "Where to get more apps and add-ons".
For information on how to create your own apps, read the Developing Views and Apps for Splunk Web manual.
