Integrating your MettleCI Workbench with ServiceNow will enable MettleCI Workbench to perform a dynamic lookup when linking DataStage Git commits to one or more ServiceNow work items directly within the Workbench user interface. It is a two-step process, there are some items to configure and collect from the Service Now ServiceNow instance, and then some items to configure in Workbench.

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”:

• Field list

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

  • URL: The URI of your Service Now ServiceNow 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 dialog below uses change_task incident 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. The example dialog below includes a filter on the status column, which limits the result to rows where the value of the column is “Active” Leave this field empty if you do not wish to filter results.
