Sentinel Timeline

The Timeline report shows a timeline for the events raised against the entities of the reported asset.

In the Asset Report, you can filter the events using Time Selection, Category, and Monitor Name.

The report asset events are limited by the filtering options. You can further limit the report asset events by adjusting the time slider. The time slider works with the time selection.

• Click the Timeline tab in the Events pane to view the Timeline.
• Use the time slider and other controls to refine what is shown on the graph.
• Click and drag the report hairline to zoom in and further refine what is shown on the graph.

The timeline report shows the event data for the asset, over a period of time. Events are displayed on the graph as circles, each one rendered in its severity colour.

In addition to the events, the asset data can also be displayed on the graph.

The important features of the Timeline Report are:

	Feature name	Applies to:	What it's useful for
	Asset Data	Asset Data	The test process input entity is automatically selected here. For attributes: all other attributes of the source entity asset, as well as the source asset itself, can be selected here. Select the check box for the entity or attribute. A colour is assigned and displayed in the corresponding colour key box . Asset data is for the primary template attributes, as well as any secondary template attributes. For primary template attributes, the template is implicit in the asset name, for example: Derby:Oil Production (the primary template [Production] is not included in the name here). For secondary template attributes it is explicit, for example: Derby[Water Injection Well]:Choke, where [Water Injection Well] is a secondary template. If the asset is a tag, this is displayed here. Note that you cannot select data that is based on a calculation.
	Additional Data	All Data on the Graph	Select any additional data (irrespective of the Asset Data in this report) using the Server Browser. Add tags, attributes or attribute values, as shown in the following section. A colour is assigned and displayed on the graph in the colour of the corresponding colour key box .
	Report Presentation	Asset Data	Graph Type: Select a data representation icon from the drop-down list. Select the continuous data representation icon to view continuous data, or the discrete data representation icon to view discrete data. Sample Method: Select Raw, Linear Interpolate, Average or Last Known Value data from this drop-down list. Sample Interval: Select the regular interval to collect sample data from the source. At every sample interval, the collected data is prepared according to the sample method used. Autorange: Select Events from the drop-down list to set the graph range to best represent the event data. Select Data to set the graph range to best represent the asset data. The third option is None: this provides a standard range of 0 through 10,000. Filter Severity of None: Select this check box to filter the events so that those of severity None are not displayed.
	Event Severity	Event Data	This is a linear representation of event severity and duration over the full timeline of the graph. The colouring represents the severity, and the width of each portion represents the duration. Note: this is the maximum severity over the period.
	Report Hairline	All Data on the Graph	Move the report hairline to get an exact time for any point in the timeline. To zoom in to a segment of the period, click and drag the hairline.
	Asset Data Plot	Asset Data	Entities, attributes, or attribute values that are selected in the Asset Data and Additional Data selection are plotted on the graph, in their respective colours (as shown in the colour keys).
	Additional Data Plot	All Data on the Graph	Selected assets from the additional data list are plotted on the graph, in their respective colours (as shown in the colour keys).
	Event	Event Data	Every event within the selected report period is displayed on the graph. Click an event icon to view event details, view event information, and add or view comments, as described in the Timeline Events section.
	Value Axis	All Data on the Graph	These mark the different values reached by event data and asset data. The range is automatically generated, to cover the full scope of either event data or asset data, depending on which auto-range (see notes above) is selected.
	Time Axis	All Data on the Graph	The timeline, for the full duration of the report period, divided into the time intervals specified in Sample Interval.
	Report Hairline Date and Time Label	All Data on the Graph	The exact date and time on the graph at the point of the hairline.

When you click and drag a hairline and then release, you can zoom in on a specific section of the graph to view more detail, as shown below. To zoom out again, click Refresh or Refresh to Now on the tab header bar.

Rotate the mouse wheel to scroll over a trend. This moves the time slider. Scroll down to move the time slider backwards, and up to move the time slider forwards.

In the events grid, every time you click the View Asset Report icon, a new asset report opens for the event. This report focuses on the event you have selected, with the Event, Info and Comment screen already open for that event.

For example, if you click on the view asset report icon for the selected row:

The Event, Info and Comment screen appears in the timeline report for this event:

Timeline Events

The different events on the Timeline graph are each represented as a circle coloured in the correlating event severity colour. Events that have comments are depicted with a small diamond background.

For example:

An event with a High Severity (Red). An event with a Medium Severity (Orange). The event contains comments, as depicted by the diamond-shaped background icon.

Note: Asset lines for events with a confidence lower than 100 appear faded; the lower the confidence, the more faded the asset line appears.

To view timeline event details, information and comments, or to add event comments:

• Click on an event in the graph.

A small event screen is displayed, with three tabs: the Event tab, the Info tab, and the Comments tab.

Event tab: This tab displays general information relating to the event.

Start Time: The date and time (to the second) that the event began.

End Time: The date and time (to the second) that the event ended.

State: The state that was reached to cause the event.

Severity: The state severity.

Info tab: This tab shows the state of the test entity at the time that the event was reached. Use the scroll bar located on the right to see the full list.

Value: The value of the test entity.

Confidence: The confidence value of the test entity.

Limit Values: The values of the different process limits as set up in the test. Depending on the process used, these could be any of the following:

• High High Limit: The value of high high limit at the time of the event.
• Min: The value of min at the time of the event.
• Max: The value of max at the time of the event.
• And so on. The value may be a fixed value, or an entity or attribute value, depending on how the limits are defined in the test process.

Auxiliary Data: If there is auxiliary data for the test, this appears in the Info tab.

• [Token 1]: Auxiliary Data (1) value
• [Token 2]: Auxiliary Data (2) value
• Etc.

State Reason: If the state configuration for this event’s state has a State Reason, this is saved with the event and displayed here.

The Case Panel opens, showing the following information.

Case Id: A unique number identifying the case.

Title: The case’s title. This is defined in Sentinel, but can be edited in Explorer.

Asset: The asset is the subject of a case. This matches the subject of the current asset report.

Raised Date: The same date and time that the event was raised.

State: This refers to the case’s status. When a case is raised, its status is New. Cases are manually progressed through various statuses in Explorer. Possible statuses are New, Investigating, Confirmed, Closed, and Rejected, and Deprecated.
