We’ve had some requests in past months about developer documentation for writing custom Configuration Wizards for Nagios XI. Many admins have a large amount of devices of a specific type that they regularly need to add to their monitoring environment. So for those needing to write their own wizard, and don’t mind getting their hands dirty with PHP development, this document and example code illustrate how to write a monitoring wizard while maintaining the integrity of the Nagios XI framework. The example wizard utilizes a weather alerts check plugin written by Tony Yarusso. You can find the document on the Nagios Library.
