Data connection

The connection is a very specific alert gateway process, querying real-time and historical alerts. Alerts are published into a fixed table dxATAlert and the displayed table is kept in dxATItemCurrent. A Data Source is not needed as all modification of the view lies within Dashboards.

You can tick/untick the visible columns in the Style editor. There are some miscellaneous columns (tag1, tag2, etc.) that you can populate freely and then change the column header within Dashboards if you want more customised information in your alert table.

Cases Display Type

Sets the way alerts and cases are displayed

  • Combined - Data Grid displays both alerts and cases.

  • Tabs - Alerts and cases are displayed in separate tabs. When selected, the Selected Tab option will be available.


Selected Tab

Determines the default Tab to be displayed when the Action Tracker is launched. This property is only available when the Cases Display Type property is set to a value of Tabs.

  • Alerts - Displays Alerts tab when Action Tracker is launched. This is the default.

  • Cases - Displays Cases tab when Action Tracker is launched.



User Defined

When checked, the selected column will remain in the Data Grid if the selected column variable is removed from the query. A user-defined query is effectively a ‘lock’ on the column

Watch out

If the User Defined column variable is missing in the query, the User Defined column will show as an empty column in the Data Grid

Data Field Name

A Data Source column or a wildcard column


When using a wildcard, all dynamic columns derived from a query will use the wildcard column format. The wildcard can be used in conjunction with text headers; e.g. bid* for both bid and bid_update.

Select the Data Field Name from data columns in the Data Source query.

Additional columns can be added, including wildcard columns. If a wildcard is used, any undefined columns will adopt the properties of the wildcard column; e.g. data alignment, decimal precision etc.

Display Name
Width (relative)


Relative to the width of the Data Grid. The scale is contingent on the values of each column; for example, columns with a relative width of 20, 10, 5, 1 will scale at a column width of 55% (i.e. 20/(20+10+5+1)), 28%, 14% and 3%.

Relative columns will scale according to the browser size.


Minimum Width (pixels)
Minimum width in pixels for a column. Columns with this set will scale according to browser size.
Text Align
Horizontal alignment of values within cells

When checked, users clicking on a column header will toggle between ascending and descending sort.

Filters applied to the main grid are also by default applied to the historical grid. This section helps to override those filters.


Selected Action Tracker data column of filter to override

Set value; for example, keep value empty for "Assignee" to not apply the filter for assignee column (that is used in main grid).

Value can be linked to a View State Parameter ("Tag1"-value can be bound to a list of values selected and set via "Actions" in main grid)

Filter override not displayed

Highlight Rules

Used to apply color updates to notify users of changes in grid values

Highlight rules in operation


Name of the rule
The grid column to which the rule will apply. It can be any column; it does not have to be the Condition Source

Data from the Condition Source (a Data Source column) is tested with the Condition Operator against the Condition Value – typically previous value.

The Condition Operator may be a numeric comparison, but can also test for strings in text values.

The cell text color when the Condition rule is true
Background Color
The cell background color when the Condition rule is true
Border Color
The cell border-color when the Condition rule is true
An icon to appear when rule is true
Icon Color
The color for the icon (if used) when rule is true

Action Type Cases

Users can create individual actions, which can be (optionally) associated/linked with other actions to form a case. Action creation requires Case Management in Basics to be enabled. The Case Management UI calls dxATCreateItem with 3 parameters, these are:

  1. The Action Tracker
  2. Action Tracker Parameter Dictionary.
  3. Action Tracker Payload Dictionary (i.e. any new columns added to the properties section)

    Sample Dictionary Parameters

    If the following parameters are specified in the UI: description, sym, alertkey, source, alertClass, tag1, tag2 and tag10, then the dictionary key will look like:

    q `sym`alertkey`source`description`alertClass`tag1`tag2`tag10

Create a Case

  • Select available Action Type from dropdown. This is a list of available Action Trackers and is the only required parameter


Standard editable actions are: description sym alertkey source alertClass, but these are not required parameters.

  • Add each supported Action Type for a case. More than one Action Tracker can be added


  • Click Screenshot to add an action


  • Additional properties can be added to a case; added properties will appear in the case property panel.



New column items are added to dxATAlert.


  • Tags can be used and renamed in Dashboard Column Properties


  • View action (use filters if necessary); it will have it's own unique ID.


  • An option to link the created action with other actions is available as a tab


Linking Actions

Actions can only be linked when Case Management in Basics is enabled, otherwise this panel will be hidden.

  • When adding a link, select from Link type and Items (Action ID). Available link options are relates to, derives to, is derived from, is dependent to, depends on, is blocked by, blocks, duplicates, is duplicated by



Linked actions can be viewed with a double-click. This will also open a tab for linked actions.


  • All linking activity is recorded in the Activity tab



Configure the content and layout of the payload panel


Allow Payload Editing

When checked, allows users to edit the details of the Alert:


Extras Template

Apply HTML customizations with Handlebar helpers; for example:

HTML Templates for Alert Title, Alert Details and Alert Dialog, and Handlebar helpers to map data into the template.

The Action Tracker has the following HandleBars helper function:


Finds all kdb timestamps in a given string and converts them to a different format. If the date format parameter is omitted, the default conversion format is YYYY-MM-DD HH:mm:ss.SSSSSSSSS. The resulting value outputs the date and time based on the timezone setting in the Dashboard.


  • string {String}: The string containing kdb timestamps.
  • date format {String}: Optional. The date format used for conversion. Refer to moment for available formats.

Returns {String}: The string containing the converted date formats


{{formatTimeStamps "Sample date: 2019.12.31D15:30:11.000000000" "MM-DD-YYYY HH:mm:ss.SS"}}
<!-- results in:  "Sample date: 12-31-2019 15:30:11.00" if timezone is set to UTC --> 
<!-- results in:  "Sample date: 12-31-2019 10:30:11.00" if timezone is set to New York --> 
<!-- results in:  "Sample date: 01-01-2020 00:30:11.00" if timezone is set to Tokyo -->
Activity Character Limit

Specify character limit in activity logs record.

Virus scanning

Files uploaded via the Upload component, and attachments uploaded via the Action Tracker, may be screened for viruses.

Two prerequisites for virus scanning:

  1. ClamAV installed on the appserver box with up-to-date definitions.
  2. Virus scanning enabled in delta.profile as follows:


    Restart the appserver to pick up any changes to the above environment variable.

Confirm virus scanning is enabled

Check the running Tomcat process: bash $ using ps -ef | grep tomcat and look for bash -DdeltaAppServerVirusScanEnabled=true or bash -DdeltaAppServerVirusScanEnabled=false

With virus scanning enabled, uploaded files will automatically be scanned and, if they fail the virus check, the upload is aborted and an error reported on the dashboard.
