Logging is the process of printing out run-time information to the console or to a file. In the context of Red5 Pro, logging occurs at the global server level and or the applicaiton level by using custom logback files. In this tutorial, we will be adding custom logging to our example application that we have been building throughout this series.

Download the Red5 Pro Server Download the latest Red5 Pro Server!

Register A Red5 Pro Account

If you have not done so already, register for an account at https://account.red5pro.com.

* A Trial Account allows for up to 10 concurrent connections, while the Professional license has no connection limit.


The following are required to setup the Red5 Pro Server and to follow along with this example:

The Red5 Pro server requires Java 1.7+ or higher. Install Java 1.7+ or higher if not already installed on your machine.

Red Pro Server Installation

  1. Download the Red5 Pro server from the downloads section of the Red5 Pro Accounts site.
  2. Unzip into a location on your local system. For the purposes of this tutorial, we will unzip the Red5 Pro server to: /Users/red5pro-user/red5pro on OSX or /home/red5pro-user/red5pro on Linux.
  3. Start the Red5 Pro server: •  On OSX & Linux: Open Terminal, cd into your Red5 Pro install directory and issue this command: ./red5.sh •  On Windows: Navigate to the Red5 Pro install directory in a File Browser and double-click on red5.bat
  4. After the server has started, open a web browser and navigate to http://localhost:5080
  5. If the server has started successfully, you should see the default landing page for the Red5 Pro server install •  The landing page can be found at /webapps/root/index.jsp of your Red5 Pro installation. You can modify or remove it as desired. For now, we will use it to navigate around and demonstrate what the Red5 Pro server can do!

Eclipse IDE

For the examples, we will be demonstrating how to set up the project in the Eclipse IDE. The steps for setup should be transferrable to the IDE of your choice, as it is the code and method of deployment that we will be more focused on.

Source Code

The source for this example can be checked out from the following Github repository: https://github.com/red5pro/red5pro-dev-series.git

Add Log Statements

Watch a demonstration of the current section
  1. Inside of eclipse, navigate to src > main > java
  2. Open ExampleApplication.java
  3. Add the following code inside of the appStart method.

         ScheduledExecutorService executor = Executors.newScheduledThreadPool(1);
         Runnable task = () -> log.debug("Scheduling: " + System.nanoTime());
         int initialDelay = 0;
         int period = 1;
         executor.scheduleAtFixedRate(task, initialDelay, period, TimeUnit.SECONDS);
  4. Verify that the code looks the same as https://github.com/red5pro/red5pro-dev-series/blob/master/06-application-level-logging/example/src/main/java/com/red5pro/example/ExampleApplication.java
