Management

This section’s procedures show how to perform common tasks such as adding and removing users in your group, managing—stopping, starting, and restarting—the Pepperdata services, and monitoring Pepperdata stats and log files.

• Managing Users and Roles with RBAC
  Using Role Based Access Control (RBAC), you can configure access policies and manage users for your group—your organization.

• Managing Pepperdata Services
  You can stop and start the Pepperdata services or refresh the Pepperdata configuration settings anytime.

• Monitoring Pepperdata
  Pepperdata processes provide a rich set of stats via the ResourceManager’s JMX service and by writing detailed operations information to log files. By using a Web browser, you can access all the published stats, and you can view the log files in the same manner as any program’s logged information.

• Obtain Hadoop Container Logs
  The Pepperdata dashboard can tell you a lot about how your application is performing, but sometimes you need to answer a “why” question such as “Why did my reducers start seeing heavy GC pauses?” or “Why are my mappers taking an hour to complete?” The best way to answer these sorts of questions is to go to the source: the Hadoop container logs.

• Obtain Pepperdata Downloads via cURL or Wget
  The Pepperdata installation files and artifacts are available from the Downloads page. But you can also obtain the installation files and artifacts by using cURL or Wget commands—perhaps to save time and more easily manage many target machines. You must first generate an API key, and then include it in the cURL or Wget command’s Authorization field.
