You can monitor the current status of each model in the model manager. The card for a model shows the current mode for this model (such as production mode) and whether it is in the Active (deployed) or Inactive state.
If a model failed to deploy or failed while running, is shown on the card for the model. To find out whether a model has failed while processing data, reload all models in the model manager to show their latest states. See also Reloading all models.
