Set up a tracing system for your exposure data source to identify potentially exposed employees by running the diagnostic requests for an affected employee.

About this task

For more information about the available tracing systems, see Tracing systems in Emergency Exposure Management.

1. Navigate to Emergency Exposure Management > Administration > Tracing Systems.
2. Click New.
3. On the form, fill in the fields.

   Table 1. Tracing System form

   Field	Description
   Title	Title of the tracing system. The title is displayed as an option for selection in the Tracing system list on the Diagnostic Request form.
   Name	Name of the tracing system.
   Parent	Tracing system for a group of other tracing systems having the similar type of input data source. If the tracing systems are in a group, only the parent tracing system displays in the Tracing system list on the Diagnostic Request form.
   Active	Option for making the tracing system active. Only active tracing systems are available for selection as a data source for the diagnostic requests.
   Requires dates	Option for enabling the start and end dates to specify a period for querying the data source for the tracing system. If selected, the Start date and End date fields appear when you select this tracing system on the Diagnostic Request form.
   Processing script tab
   Condition	Condition to determine the tracing system data for the diagnostic request on selecting a parent tracing system. For example, if two tracing systems A1 and A2 have the same parent tracing system called A. In a diagnostic request, if you select A as the tracing source, the condition determines whether to query data from A1 or A2. For reference, you can review the condition scripts of the base tracing systems Cisco DNA Spaces and Mist System having the parent tracing system as Wi-Fi access log. This field appears only when a tracing system is selected in Parent.
   Use parent processing script	Option for executing the processing script of the parent tracing system. The parent tracing system's processing script populates the potentially exposed employees data in the corresponding related list on the Diagnostic Request form. If you select this option, the current tracing system's processing script does not process. This field appears only when a tracing system is selected in Parent.
   Processing script	Script to populate the potentially exposed employees data in the corresponding related list on the Diagnostic Request form.
   Contact graph tab
   Legend icon	Icon representing the tracing system as data source for the potentially exposed contact's in the potentially exposed contacts visualization on the Case form. For more information, see Working on a case through contact tracing visualization.
   Legend tooltip	Tooltip text that appears when you point to the legend icon.
   Order	Order in which the icons appear in the Reason for exposure section.

4. Click Submit.

Result

The tracing system is created. The tracing system appears as one of the options in the Tracing system field on the Diagnostic Request form.

What to do next

• Associate a system property with a tracing system.
• Create or modify a diagnostic request task configuration.
