Selecting a Point In Time or a Time Range

Depending on what page the Time Line appears, you can select a point in time or a time range.

There are two ways to look at information about your cluster—its current status and health, or its status and health at some point (or during some interval) in the past. When you are looking at a point in the past, some functions may not be available. For example, on a Service Status page, the Actions menu (where you can take actions like stopping, starting, or restarting services or roles) is accessible only when you are looking at Current status.

Selecting a Point in Time

Status information on pages such as the service Status pages, reflects the state at a single point in time (a snapshot of the health and status). When displayed data is from a single point in time (a snapshot), the panel or column displays a small version of the Time Marker icon () in the panel. This indicates that the data corresponds to the time at the location of the Time Marker on the Time Line.

By default, the status is shown at the current time. If you specify an earlier point on the time range graph, you see the status as it was at the selected point in the past.

When the Time Marker is set to the current time, it is blue ().
When the Time Marker is set to a time in the past, it is orange ().

You can select the point in time in one of the following ways:

By moving the Time Marker ()
When the Time Marker is set to a past time, you can quickly switch back to view the current time using the Now button ().
By clicking the date, choosing the date and time, and clicking Apply.

Selecting a Time Range

Pages such as the Logs, Events, and Activities show data over a time range rather than at a single point. These default to showing the past 30 minutes of data (ending at the current time). The charts that appear on the individual Service Status and Host Status pages also show data over a time range. For this type of display, there are several ways to select a time range of interest:

Drag one (or both) edges of the time range handles to expand or contract the range.
Choose a duration by clicking a duration link and then do one of the following:
- Click the next or previous buttons to select the next or previous duration.
- Click somewhere in the dark portion of the time range to choose the selected duration.
Click the date range

to open the time selection widget. Enter a start and end time and click Apply to put your choice into effect.
When you are under the Clusters tab with an individual activity selected, a Zoom to Duration button is available. This lets you zoom the time selection to include just the time range that corresponds to the duration of your selected activity.
