Dashboard at a Glance


Summary Information

Orders

This widget displays the number of orders per state.

  • Find information about order states in the JS7 - Order State Transitions article.
  • Find details about this widget in the JS7 - Orders article.
  • The Order Summary is displayed for the selected date range (today, next hour etc.).
  • Users can click the indicated numbers to find details with the Orders View.


History

This widget indicates the number of completed orders and tasks for successful and failed end states.

  • Find details in the JS7 - Order History View and JS7 - Task History View.
  • The History Summary is displayed for the selected date range (today, last hour etc.).
  • Users can click the indicated numbers to find details with the respective History View.

Daily Plan

This widget displays the percentage of orders states in the daily plan.

  • Find details in the JS7 - Daily Plan View.
  • The Daily Plan summary is displayed for the selected date range (today, next day).
  • Users can click the indicated bar to find details with the Daily Plan View.

Inventory

This widget indicates the number of deployed Workflows & Jobs, Locks for mutual exclusion and Schedules.

System Status

Cluster Status

The widget provides an overview of components, operational status and connection status in a JS7 scheduling environment.

  • Connection Status
    • JOC Cockpit instances are connected:
      • to a Database,
      • to Controller instances, e.g. to a Standalone Controller or to a Controller Cluster with a Primary and Secondary Controller instance.
    • Controller instances in a cluster are connected to each other.
    • The connection status, i.e. the lines between components are displayed with the following colors:
      • The connected status indicates a working connection.
      • The unstable status indicates that the connection works but had errors during the last 30 minutes.
      • The unknown status indicates that the connection could not be established. This does not indicate that the component is not running as e.g. network issues can prevent a connection from being established.
  • Component Status
    • The component status is indicated with the colored square in the left upper corner of each component.
    • The green component status signals availability, the red square signals an unknown component status as the component is not connected.
  • Cluster Node State
    • The cluster node state is displayed for:
      • a number of JOC Cockpit instances running in parallel.
      • a Primary Controller instance and Secondary Controller instance in a Controller cluster.
    • JOC Cockpit
      • JOC Cockpit can be implemented as an active-passive cluster with any number of instances.
        • The active JOC Cockpit instance displays the active cluster node state.
        • Additional JOC Cockpit instances display a standby or unknown cluster node state.
      • The currently used JOC Cockpit instance is displayed with a thick border and offers a context menu:
      • Standby JOC Cockpit instances offer a switch-over function with their context menu that causes the standby instance to become the active instance in a cluster. Switch-over typically is performed within 60s as this is not considered an emergency fail-over but normal operation that leaves running background services enough time to complete their tasks.
    • Controller
      • A Controller can be implemented as an active-passive cluster with two instances.
      • Cluster Node State
        • The active Controller instance and the standby Controller instance cluster node states are displayed. Controller instances with an unknown component status are not connected to a JOC Cockpit instance and their cluster node state cannot be determined.
      • Cluster Status
        • The Coupled cluster status indicates a working cluster with Controller instances being synchronized.
        • The ClusterNodesAppointed and PreparedToBeCoupled cluster status indicate that the cluster currently is connecting and respectively is synchronizing past events which occurs after a restart of one or both Controller instances. This is a temporary status until the synchronization is completed
        • The PassiveLost cluster status indicates that the standby Controller instance is not connected to the active Controller instance. The active Controller instance will continue to execute workflows and jobs, however, this cluster status indicates loss of high-availability.

Agent Status

The widget displays a pie chart showing the connection status of Agents:

  • Agents in a Coupled state are connected to a Controller and can run jobs.
  • Agents in a Coupling state are prepared for connection by a Controller.
  • Agents in a Coupling Failed state are not connected and cannot run jobs.

Clicking the respective section of the pie chart navigates to the Resources -> Agents View to display details about individual Agents.

Agent Running Jobs

The widget displays the number of tasks, i.e. jobs running, for each Agent.

  • The widget displays Agents in the order of frequency of parallel jobs. The length of the bar indicates the number of jobs running in parallel.
  • Users can modify the widget size to display for example the 30 Agents with the highest number of parallel jobs.

Controller Status

The widget displays the status of any Controllers connected to JOC Cockpit.

  • A Controller can include one standalone instance or a primary & secondary instance in a cluster. Controller instances in a cluster share the same Controller ID.
  • Any number of Controllers can be connected to JOC Cockpit. Users can switch between Controllers by clicking the indicated Controller ID. For similar purpose the right upper corner of the JOC Cockpit screen offers a list box for switching Controllers.
  • Consider that the user profile can be configured per Controller, i.e. you could use different themes per Controller.

Dashboard Layout

The Dashboard View allows the layout to be modified using the Edit Layout and Reset Layout buttons.

This allows to select/unselect widgets for display, to position widgets freely on the screen and to apply an individual size per widget.

Resetting the Dashboard layout will revert the display to the layout described above.
