2. Create a Dynatrace API token with the following permissions:

   1. API v2: Read entities

   2. API v2: Write entities

   3. API v2: Ingest metrics

   4. API v2: Ingest events

...

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

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

• Verify Nagios SSL certificate - Verify Nagios SSL certificate

• Nagios CA certificates - Path to CA bundle with CA certificates to be used for verification (if using custom CA) in PEM format. Used only if verification is turned on. If not specified, built-in CA certificates are used.

• Nagios HostGroups to include - Semicolon delimited list of Nagios host groups to include in integration. Only member hosts are included other hosts are ignored (mandatory to fill)

• Nagios Service names to include - Service names specified as regular expressions delimited by a semicolon (other services are ignored), e.g. Mem.*sage;HTTP;Swa.*

• Nagios metadata keys - Semicolon separated names of Nagios host attribute keys to be used in Custom device metadata

• Nagios alert keys - Semicolon separated names of Nagios alert state attribute keys to be used in Custom event metadata

• Nagios refresh hosts - Interval (in minutes) for querying Nagios API for hosts and inventory data. Hosts and inventory is are queried on extension startup and periodically afterward (mandatory to fill)

• Notification enabled - Catch states with enabled notification only

• Nagios host DOWN - Nagios severity to Dynatrace severity mapping

• Nagios host UNREACHABLE - Nagios severity to Dynatrace severity mapping

• Nagios service CRITICAL - Nagios severity to Dynatrace severity mapping

• Nagios service WARNING - Nagios severity to Dynatrace severity mapping

• Nagios service UNKNOWN - Nagios severity to Dynatrace severity mapping

• Dynatrace Environment URL - URL for Dynatrace environment used for Entity v2 API calls (mandatory to fill)

• Dynatrace API Token - Dynatrace API token with the following scope access (mandatory to fill)

  • API v2: Read entities

  • API v2: Write entities

  • API v2: Ingest metrics

  • API v2: Ingest events

• Verify Dynatrace SSL certificate - Verify Dynatrace SSL certificate

• Dynatrace CA certificate - Path to CA bundle with CA certificates to be used for verification (if using custom CA) in PEM format. Used only if verification is turned on. If not specified, built-in CA certificates are used.

• Dynatrace refresh host entities - Interval (in minutes) for querying Dynatrace API for hosts and their IP addresses. Hosts are queried on extension startup and periodically afterward (mandatory to fill)

• Dynatrace problem resend time - Interval in minutes for resending events to Dynatrace to keep the problem opened in Dynatrace (otherwise expires after 15 minutes) (mandatory to fill)

• Problem metric - Send problem metric (count of problems for each created custom device)

• Performance metrics - If there is no definition then no performance data are transferred. Define regular expressions/substrings delimited by a semicolon specifying service list (e.g. Mem;HTTP;Swa.*) Performance data for matching services list will be transferred into Dynatrace.

• Metrics to hosts - Send Nagios metrics to the Dynatrace host. Infrastructure metrics are monitored by the Dynatrace agent, therefore Nagios metrics are not sent by default. Turn on if you want Nagios metrics to be sent to hosts monitored by the Dynatrace agent.

• Candidate to Custom device - Create a Custom device for Monitoring candidate, if not enabled events are sent to the monitoring candidate host

• Use Events API - If enabled, Nagios problems are sent using Events API instead of the ActiveGate extension.

• Allow Davis merge - Allow Davis AI to merge events into existing problems (true) or force creating a new problem (false)

• Debug - Set to on to enable DEBUG logging on each extension query run
