Splunk is a powerful log analyzer that can be used to obtain insight into your infrastructure. Splunk collects, monitors, analyzes, and visualizes data from database applications, web servers, cloud networks, and a variety of other sources.

Deploying the Splunk Marketplace App

The Linode Marketplace allows you to easily deploy software on a Linode using the Linode Cloud Manager.

  1. Log in to the Cloud Manager and select the Marketplace link from the left navigation menu. This displays the Linode Compute Create page with the Marketplace tab pre-selected.

  2. Under the Select App section, select the app you would like to deploy.

  3. Fill out all required Options for the selected app as well as any desired Advanced Options (which are optional). See the Configuration Options section for details.

  4. Complete the rest of the form as discussed within the Getting Started > Create a Linode.

  5. Click the Create Linode button. Once the Linode has provisioned and has fully powered on, wait for the software installation to complete. If the Linode is powered off or restarted before this time, the software installation will likely fail. To determine if the installation has completed, open the Linode’s Lish console and wait for the system login prompt to appear.

  6. Follow the instructions within the Getting Started After Deployment section.

Software installation should complete within 2-5 minutes after the Linode has finished provisioning.

Getting Started after Deployment
