Use the Lens Apps app info -a to see the unit state.

The following list describes the available states for units in Lens AppIQ:
- Created is the initial status of an unit.
- Building is the status for units being provisioned by the provisioner, for example during deployment.
- Error is the status for units that failed to start, because of an application error.
- Starting is set when the container is started in docker.
- Started is for cases where the unit is up and running.
- Stopped is for cases where the unit has been stopped.
The unit state flow can be represented by the following chart:
+----------+ start +---------+
