    Por Que e Quando Desempenhar Esta Tarefa

    ServiceNow Contact Tracing integrates with an external application, Mist Systems, to collect and process Wi-Fi access logs for organizations. To leverage access logs from Mist Systems, you must have Mist access points installed at your workplace.

    Procedimento

    1. Set up the Contact Tracing Wi-Fi properties.
      • By default, the asset data is available in the Computer table [cmdb_ci_computer]. If you are using a different table, specify it using the sn_imt_tracing.wifi_client_table property.
      • Ensure that the MAC address is populated in the mac_address field in the table that has the asset data.
      For more information, see System properties for tracing systems in Emergency Exposure Management.
    2. Set up the Contact Tracing BLE properties.
      • By default, the asset data is available in the Wearable Technology [cmdb_ci_wearable] table. If you are using a different table, specify it using the sn_imt_tracing.wifi_ble_client_table property.
      • Ensure that the MAC address is populated in the mac_address field in the table that has the asset data.
      Nota:
      The Wearable Technology [cmdb_ci_wearable] table is installed with the CMDB CI Class Models application available on ServiceNow Store. For more information, see CMDB CI Class Models.

      For more information on adding BLE-enabled devices or other wearable devices, see Add wearable devices assigned to employees.

    3. Set up an organization and load sites.
      For more information, see Set up an organization and load sites.
    4. Indicate that the diagnostic data should be accessed from Mist Systems.
      1. Navigate to Contact Tracing > Wi-Fi Access Management > Wi-Fi Diagnostic Preferences.
      2. Click Generate Location Preferences.
      3. In the Generate Location Preferences window, select Use Mist Integration from the list.
      4. Click OK.
      The access log data for all locations will be taken from Mist Systems access log files.
    5. If you want to use manually loaded access logs rather than Mist Systems logs for a specific location, create a separate location assignment.
      1. Click New.
      2. Specify the location for which you want to set the diagnostic preference.
      3. Set the Preference value to Use Manual Load.
      4. Click Submit.
    6. Run the diagnostic request.
      1. Select the Use Wi-Fi access log check box.
      2. Specify the start date and end date.
      3. Click Run Diagnostics.
      For more information about how to run a diagnostic request, see Run a diagnostic request.

    Resultado

    Mist Systems identifies the MAC addresses of the affected user for the specified start date and end date. The MAC addresses identify the zones visited by the affected employee. Potentially exposed employees who visited those zones are identified and displayed in the related list of the diagnostic request.
