Release Notes

Node properties affect AppDynamics behavior for monitoring a node, for example, enabling or disabling features or setting maximum values for the number of discovered business transactions or the minimum number of requests to evaluate before triggering a diagnostic session. Node properties are inherited from the parent application or tier or customized for a specific node.

You can edit the values of the default node properties either in the app-agent-config.xml file or from the UI. To see the default node properties, follow steps 1 through 3 in To edit a registered node property.

In addition to the default node properties, there are additional custom node properties that AppDynamics Support may recommend that you set to solve a particular problem. The custom node properties are not available unless you register them.

To edit a registered node property

  1. In the left navigation pane,  access the node dashboard for the node for which you want to configure a property. For example, click Servers - > App Servers -> <tier> -> <node>. The Node Dashboard opens.
  2. In the Node Dashboard, click Agents->Configure The App Server Agent Configuration window opens.
  3. In the left panel, select the application, tier, or node for which you want to edit a node property.
  4. Select Use Custom Configuration.
  5. From the list of node properties, select the property that you want to edit. You can use the search box on the upper right to find the property by name.
  6. Click the Edit Property icon.
  7. In the Edit Agent Property window, update the value of the property.
  8. Click Save.
     

You can copy the configuration to other nodes, to the tier, or apply it to the entire application.

To apply the configuration to all nodes

If you just Save but do not click Apply to All Nodes, the new configuration applies to new nodes going forward but does not overwrite custom configuration for existing nodes.

If you are configuring at the application level, click Apply to All Nodes if you want the new configuration to overwrite all nodes in the entire application, including nodes with custom configuration. This erases the previous custom configurations for the application.

If you are configuring at the tier level, click Apply to All Nodes in this tier if you want the new configuration to overwrite all nodes in the tier including nodes with custom configuration. This erases the previous custom configurations for the tier.
