Before configuring the extension in the Dynatrace UI, please

  1. Create a Nagios user that the extension will use if you don’t want to use nagiosadmin user

Extension endpoint configuration provides these options:

  • License - Valid license required (mandatory to fill)

  • Nagios URL - Nagios Server web URL (mandatory to fill)

  • Nagios Username - User name to connect to Nagios API (mandatory to fill)

  • Nagios Password- Password to connect to Nagios API (mandatory to fill)

  • Nagios host groups to include - At least one Nagios HostGroup should be defined for synchronization (mandatory to fill)

  • Problems title prefix - The Nagios problem title will have a defined prefix if we want to distinguish problems from Nagios from problems generated from Dynatrace. We recommend the prefix [Nagios] with one space at the end.

  • Problems not older than - Synchronize problems not older than specified days. 0 means no limit for problem age.

  • Nagios refresh hosts list - Interval (in minutes) for querying Nagios API for hosts and inventory data. Default value 20 minutes

  • Dynatrace problem resend time - Interval in minutes for resending events to Dynatrace to keep the problem opened in Dynatrace (otherwise, it expires after 15 minutes). Each problem event sent consumes 0.001 DDU

  • Notification enabled - Catch only Nagios problems with enabled notification

  • Nagios service names filter - Nagios service names specified as regular expressions or name substrings.

  • Performance metrics - If there is no definition then no performance data are transferred. Define regular expressions or substrings. Performance data for the matching services list will be transferred into Dynatrace.

  • Verify Nagios SSL certificate - Verify Dynatrace SSL certificate

  • SSL Trust store - SSL CA certificate in PEM format for Nagios web server
