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.
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.
