If you install the Machine Agent on the machine hosting the instrumented Node.js node and you specify the tier and node name in the controller-info.xml file of the Machine Agent, the Node.js Agent will fail to register.

To avoid this problem:

• Install the Node.js Agent before you install the Machine Agent.
• If you install the Machine Agent on the machine hosting the instrumented Node.js node, do not specify the application, tier, or node name in the machine agent's controller-info.xml file. If you do, the Node.js Agent may fail to register.
