  1. Setup OAuth in ServiceNow in your ServiceNow instance.

  2. Create a new OAuth API endpoint for Workbench to access ServiceNow:

  3. Set the “Name” Field to “MettleCI Workbench” and the “Redirect URL” to https://<workbench url>:<port>/api/auth/delegated/<N> where <workbench url>is the URL of your Workbench installation (usually your Development engine), <port> is the https port you are running on (often but not always 8443, check your <config.yml file if unsure), and <N>is the index of the WIM you plan to add (the default generic is 0 and if this is the first other WIM you are adding, the value here would be 1) and click “Submit”:


    Record the redirect URL for later use so you don’t have to derive it again. If your organization has installed multiple MettleCI Workbench application, you can add them all to the same ServiceNow Application Registration by adding multiple Redirect URLs. (comma separated)

  4. Click on your newly created Application Registration:

  5. Anchor
    ServiceNowRegisterConfig
    ServiceNowRegisterConfig
    Note down the “Client ID” and “Client Secret” field properties for later use:

You are done with the Service Now portion of the configuration, but you may want to keep this open until you have validated everything is working.

  2. On the Registered Issue Management Systems screen select the “+” to create a new Issue Management type.. Initially you will have only the “Default Generic Issue Manager” present, but you can add as many as you need to (including more than one of the same type if necessary) one at a time. It is recommended that you get one working before you add another.

  • Field list

    • Name: Anything you like, but something that identifies your Service Now organisational instance would be a sensible choice

    • URL: The URI of your Service Now instance recorded earlier.

    • Client ID: Your Application (client) ID recorded earlier

    • Client Secret: Your client secret recorded earlier

    • Search Queries: This has no default, you will need to create at least one query. Consult with your ServiceNow administrators to determine what table(s) your organization uses, and thus, what table(s), then add or edit the query or queries as needed by using the “pencil” icon and “+” icon to edit what is queried or add a new table to query, respectively. The example uses change_task as the table, keyed on number with number: short_description as the summary shown to the user.

  • OPTIONAL - In the Search Queries section of any query, you can add add a filter expression to limit what is returned. Note that this expression is not checked for correct syntax. Consult with your ServiceNow administrators to determine whether you need to filter (most organizations will not) and what columns/values to filter on.

titleTips to debug when havig trouble registering new ServiceNow issue management system.
  • It is not necessary to restart the Workbench service, but if clearing the log and then restarting the service may aid in debugging

    Code Block
    $> cd /opt/dm/mci
    $> mv mci.log mci.log_preIssueManagementChanges
    $> sudo service dm-mettleci-workbench restart
  • During issue lookup, Workbench will search each ServiceNow Table configured in the Search Queries list. The Ids that will appear in the commit message are generated from the value of the “Primary Key Column” value and the text shown to the user in the lookup is generated from the “Ticket Summary Column” value. These settings are retained in the issuesmanagement-settings.yaml file in the installation directory. Assuming the choices above were made, this file would would appear like so: (ID 0 is the default generic issue management which takes no other parameters)

Code Block
---
- id: 0
  type: "GENERIC"
  name: Default Generic Issue Manager"
- id: 1
  type: "SERVICENOW"  
  name: MyServiceNow:
  url: <your ServiceNow instance URL>
  clientId: <your Client ID>
  clientSecret: "<your Client Secret>"
  search:
      - table: "change_ task"
        id: "${number}"
        summary: "${number}: ${short_description}"
        filter: "state='ACTIVE'"

Template Strings are text containing special ${column_name} variables which Workbench will replace with Column data from the ServiceNow Table based on the column_name.
