In Sentinel, several column headers offer the ability to filter data according to specified criteria. This is indicated by the filter icon on the column header.
Note: A filtered column has an opaque filter; other filter icons are clear.
To open the filter box, click the filter icon of a column header.
The filter box offers the following options:
Select All: All available options for this column are listed here. You can choose the Select All option, or you can select individual options from the list.
Show rows with value that: This section allows you to type a character or number to compare with the values in the filter column.
Note: If a column contains characters, the text box is followed by an alphabet icon. For case-sensitive matching, click on the alphabet icon. If there is no alphabet icon, type a number into the text box.
There are three optional fields to complete:
Comparison 1
Select a comparison operator from the first drop-down list, directly below Show rows with value that. For example, Is equal to, Starts with, Ends with, and so on.
Type a comparison in the first text box.
Select And or Or, if you want to compare two values.
Comparison 2
Select a comparison operator from last drop-down list. For example, Is equal to, Starts with, Ends with, and so on.
Type a comparison in the second text box.
Filter: To apply the selected filters and options, click the Filter button.
Clear Filter: To clear the selected filters and options, click the Clear Filter button.
Close the filter: To close the filter box, click the Close button at the top right.
Sorting Columns
Many of the columns in the Sentinel data grids can be sorted in ascending or descending order.
To sort by a column, click the column header to toggle through the various options:
Click once to sort ascending.
Click twice to sort descending.
Click three times to remove sorting.
Grouping by a Column in a Grid
In Sentinel, some of the grids have a grouping capability. For example, in the View Events screen you can group by a column header for the following columns:
Monitor
Asset
Entity
State
Severity
Test
Grouped columns allow you to organise the contents of the grid more easily. For example, if you group by Asset, each different asset has a single row in the grid, which you can expand to view the different rows (or groups) within that asset.
In the screenshot below, you can see groupings of Asset, Entity and State. The groupings are nested in the same order that they appear in the grid header panel, with (Asset) forming the outermost group, (Entity) showing the middle group, and (State) showing the inner group. Within the inner group, items appear with full details.
To group by a column header, click and drag the column header to the grid header (labelled Grouped By).
To expand a grouped section, click the Expand, downward-pointing arrow.
To collapse a grouped section, click the Collapse, upward-pointing arrow.
To remove a grouping, hover over the relevant column grouping button on the header panel that you want to remove, and click the Close icon that appears.
To re-order a column grouping, click and drag a column header button in the table header section, then release it in the new position. This changes the hierarchy of groupings in the grid.

Panel Comments
Many of the Sentinel panels have a comment box, where you can annotate why, for example, you have chosen to use the process, precondition, action, and so on, that you have used. If a panel has a comment box, this is depicted by a comment button on the upper right of the panel.
For example, the Precondition and the Process panels on the test screen each have a comment button (as shown in the screen image below).
If comments have already been added, the comment button is preceded by a panel comments counter button; the number on the button displays the number of separate comments for that panel.
Comment button on the Precondition panel of a test.

Note: Panel comments cannot be edited or deleted.
Report Hairlines
Report hairlines allow you to pinpoint an exact time on a graph.
In Sentinel, the following graphs have a hairline:
The Event Timeline section of the Statistics report, in the Asset report.
The Event Timeline section of the custom Event Timeline report.
The Timeline report, in Asset Reports.
To use the hairline in any of these reports:
1. Hover the mouse over the plot area of the graph (anywhere between the two axes), or in the magnifying pane of the time slider.
A fine, dashed line appears on the graph, vertically aligned to the tip of the cursor.
Alongside the dashed hairline is a text box, displaying the exact date and time (to the nearest second) of that point on the graph.
2. Move the mouse back and forth along the graph until you have the time you are interested in, or until you reach a point of interest (such as an event, for example).
In the preceding screen image, the hairline highlights a point on the graph where the date and time is: 30/11/2012 3:10:40 AM.
3. For the timeline report: to zoom into a period, click the hairline and drag it to the left or right, highlighting a section of the graph, then release the mouse button at your new start (if dragging to the left) or end time (if dragging to the right). The highlighted section of the graph replaces the original selection. To zoom back out to the original timeline, click Refresh, or Refresh to Now on the tab header bar.

Heading: Tasks for [user.name].
List of tasks: A list of tasks that the user can address.
