There are three ways to create custom tasks for your workflows.


Create a New Task Template Using XML 

AppDynamics provides a set of default task templates.  See Available Task Templates.  You can also create your own task templates using XML and the default task launcher, AntTask.

XML File Types

You must create two XML files to create a new template.  You must use these names.

The Task Library

Look through the Task Library to find a template similar to the one you are creating and download the template zip file.

  1. In the left navigation pane of the UI, select the appropriate application
  2. Click Alert & Respond -> Cloud Auto-Scaling -> Tasks
  3. Click New+.  The Create Task dialog opens.
  4. Click View All Task Templates at the bottom left.  The Task Template Library opens in the main window.
  5. Click Cancel to close the Create Task dialog.
  6. Find a similar task template.
  7. In the Task Zip File, click the zipfile name.
  8. Open the zip file.  It should contain both a run.xml and a task.xml.  If it doesn't, download a different zip file.

Create your task.xml file

Using the downloaded task.xml file as a model, create your task.xml.  See the BZip2 sample below.

	<description>Zips to a bzip file using BZip2 algorithm</description>
		<argument name="source-file" description="Source tar file to zip"
			is-required="true" />
		<argument name="destination-file" description="Destination file to create"
			is-required="true" />

Create your run.xml file

Using the downloaded run.xml file as a model, create your run.xml.  See the BZip2 sample below.


<?xml version="1.0" encoding="UTF-8"?>
<project name="run" default="run" basedir=".">
	<property file="" />
	<target name="run">
		<bzip2 src="${source-file}" destfile="${destination-file}"/>

Package the XML files as a zip archive

Add the task.xml and run.xml files to a zip archive and name this zip archive the name of the task.

Add the zip archive as a task template

  1. From the Cloud Auto-Scaling menu select Task Library.
  2. Click New+. The Create Task Template dialog appears.

  3. Provide the name and description for the task.
  4. Upload the Zip file containing the XML task files.
  5. Click Create Task Template.

AppDynamics adds the task template to the Task Library.  See Add Tasks for Workflow Steps for using this template.

Create Custom Tasks Using Shell or Batch Scripts

You can also create custom tasks by using a shell or batch script.

  1. Create the shell or batch script file on the system.
  2. In the left nav bar of the UI, select an application.
  3. Click Alert & Respond -> Cloud Auto-Scaling -> Tasks.
  4. Click New +. The Create Task window opens.
  5. Give the task a name.
  6. From the task list, select the task template ExecuteShellScript or ExecuteShellScriptNonBlocking, as necessary.
  7. Browse to find the script file.
  8. Click Create Task.

Create Your Own Task Launcher Based on a Java Class

If you need to create a completely new task that cannot be accomplished by using the AntTask launcher or by using a shell or batch script, you must create a Java class that implements the public interface bundled with the Machine Agent.

Your class must implement the following two methods:

This class is referenced in the task.xml file, in the <java-task> element.

AppDynamics highly recommends using shell/batch scripts instead whenever possible.  See for more information Create Custom Tasks Using Shell or Batch Scripts .

Contact the AppDynamics Support Team if you need additional help in creating a Java task.
