About this task

Some application CIs have configuration files containing lists of possible URLs. You can search such lists to find the match for the URL that allows connecting to a configuration item (CI).

Procedure

  1. Select Find matching URL from the Operation list.
  2. Fill in the fields, as appropriate.
    Field Description
    Values Specify the table and records containing potential URLs. You can use values from variables, including temporary tabular variables: from a specific field or a specific column in a table sequentially, starting from the first row. For more information, see Enter values and variables in patterns.
    URL Specify the URL for which you are seeking the best match.
    Target Variable Specify the variable name to contain the best match.
  3. If in Debug mode, test the step by clicking Test and checking that the operation brings the result you expected.
