Upgrade the Required Agents using Smart Agent

You require to upgrade to the latest version.  Also, refer to the agent specific documentation to meet all the prerequisites before performing an upgrade.

  1. Select the agent(s) of the same type that you want to upgrade, then click Upgrade.
  2. Select one of the following options:
    • Default Upgrade: to use the latest version with the default configuration.
    • Custom Upgrade: to specify the version and change other settings.
  3. For Custom Upgrade:
    1. Select the version that you want to upgrade in Available Versions.
    2. Select the source from where you are downloading the agent. The source can be the AppDynamics download portal (Using AppDynamics Portal), your local directory (Using Local Directory), or your custom HTTP server (Custom HTTP URL).
      If you select Custom HTTP URL and if your HTTP server requires authentication, configure smart agent to use basic authentication. See Configure Authentication for Custom Artifact Location.
    3. Retain the same configuration or edit it as required.
      The attributes are displayed based on the selected agent.

      By default, Smart Agent reuses the previous Controller configuration details. However, if you specify a new configuration in the controller-info.xml file, it takes precedence over the old configuration. If the configuration is not specified, Smart Agent uses the default value defined in the JSON file.

  4. (Optional) You can use the agent specific custom configurations to specify in Custom Configuration. For the list of keys that you can use, see Custom Configuration.
  5. Check the upgrade status in Tasks in Progress.
    You can search for the specific host and check the log file. After the task is completed it is added to the History tab.
