Viewing an Aggregated Status of a Node
Using the ActiveMatrix Administrator GUI and CLI, you can view an aggregated or cumulative status of an entity (Resource Instance or Application fragment) deployed or running on the Node. The status also includes the status of the synchronization of the Node itself. From the status, you can find out whether an entity has failed on a particular Node.
The status or health of the Node is indicated by the following states in the Node Health column of the ActiveMatrix Administrator GUI.
- Healthy: None of the entities on the Node are in failed state.
- Not Healthy: One or more entities on the Node are in failed state. You can continue to deploy the Applications; the Not Healthy state is just an indication that something has failed on the Node.
- In Progress: The Node Java Virtual Machine (JVM) is running successfully but the entities are still in the process of starting or stopping.
For example, if you restart a Node and an entity is currently being deployed on the Node, the status will be In Progress. This state indicates that some activity is in progress on the Node.
- Unknown: The Node is not in the Running state.
For example, if you create a Node and install it, the status will be Unknown (as the Node is not in the Running state yet). In such a case, try to start the Node to get it into the next transition state. Otherwise, the Node health will continue to be Unknown.
