Define comparison criteria

Updated June 7th, 2016

Defining comparison criteria enables you to filter out of comparison results lines that you do not need SolarWinds NCM to evaluate. This saves processing time and makes the review of compared files easier.

You use regular expressions to create the filters that SolarWinds NCM uses to ignore statements of the config files that you ask it to comparatively evaluate.

The regular expressions you create and enable are used throughout SolarWinds NCM to compare config files, as in performing scheduled jobs.

Access NCM Configs settings and you can then create, edit, enable, disable, or delete a regular expression.

  1. Click Settings > All Settings.
  2. Under Product Specific Settings, click NCM Settings.
  3. Under Configs, click Comparison Criteria.
  • We provide Comparison criteria: exclusion examples to help you with the regular expressions. Other resources, such as Regular-Expressions.info, are available online to learn more about regular expressions.

  2. Enter a title, and write the regular expression.
