History View
The History view displays historical data for the domain, a service, or a node. You can view historical data for the contents panel, Service State Summary, resource usage indicators, and Details panel. You can also view information about events in the domain.
The following image shows the History view:
- 1. Time line
- 2. Event circle
- 3. Last Refreshed
- 4. Time line slider
- 5. Events panel
The History view has the following components:
- Time line
- Use the time line to choose which time range and events you would like to view. When events occur around a point in time, the point is marked with a red event circle. When you select a circle, the Events panel displays the events that occurred around that point in time. By default, the time line displays crashes and unplanned shutdowns that occurred in the last one day.
- Events panel
- Displays events that occurred during a specified time range. When you open the History view, the panel lists crashes and unplanned shutdowns that occurred in the last one day.
- Contents panel
- Displays current and historical domain contents and states. When you open the History view, the contents panel shows domain objects and states at the last refresh. When you drag the time line slider to a point in time, the contents panel shows domain objects and states at that point in time.
- Service State Summary
- Displays current and historical service state summaries. When you open the History view from the domain Actions menu, the Service State Summary appears and displays the number and states of services at the last refresh. When you drag the time line slider to a point in time, the Service State Summary displays the number of services that were available or unavailable at that time.
- Details panel
- Displays current and historical state for a service or node. When you open the History view, the Details panel displays the state of the service or node at the last refresh. When you drag the time line slider to a point in time, the Details panel displays the object state at that point in time.
- Resource usage indicators
- Display current and historical resource usage information. When you open the History view, the usage indicators display the usage statistics as they appeared at the last refresh. When you drag the time line slider to a point in time, the indicators display statistics for that point in time.
The data that you view in the History view is stored in the monitoring Model repository. Before you can view historical data, you must configure the monitoring Model repository in the Manage > Services and Nodes > Monitoring Configuration tab. You can view the per-minute data for up to two weeks in the past. After two weeks, the statistics that you view are hourly averages. You can view hourly averaged data for up to one year in the past.
Note: The monitoring Model Repository Service that you configure to store the historical data cannot capture data about events that occur while it is unavailable or disabled. For example, Start events for the monitoring Model Repository Service and Crash events for the node that the monitoring Model Repository Service process runs on do not appear in the History view.

You can view historical statistics for the domain, a service, or a node.
The amount of history that you can view depends on the monitoring Model repository options that you configure in the Monitoring Configuration tab. You must configure a monitoring Model repository in the Monitoring Configuration tab before you can view historical statistics.
