 By default, Nagios can send emails to registered contact. Fortunately, there is also a contact property names ''pager'' which can be used very conveniently. Two things have to be added to your nagios config in order to reveice the Nagios notifications via DAPNET.
-===== Define DAPNET Username and Password =====
+===== Define commands to send paging calls =====
+Edit ''commands.cfg'' and add the following lines:
+<code>
+# 'notify-host-by-pager' command definition
+define command{
+        command_name    notify-host-by-pager
+        command_line    /usr/bin/curl -H "Content-Type: application/json" -X POST -u $USER12$:$USER13$ -d '{ "text": "NAGIOS $NOTIFICATIONTYPE$: $HOSTNAME$ $HOSTSTATE$", "callSignNames": ["$CONTACTPAGER$"], "transmitterGroupNames": ["$CONTACTADDRESS1$"], "emergency": false }' $USER11$/calls
+        }
+# 'notify-service-by-pager' command definition
+define command{
+        command_name    notify-service-by-pager
+        command_line    /usr/bin/curl -H "Content-Type: application/json" -X POST -u $USER12$:$USER13$ -d '{ "text": "NAGIOS $NOTIFICATIONTYPE$: $HOSTNAME$ $SERVICEDESC$ $SERVICESTATE$", "callSignNames": ["$CONTACTPAGER$"], "transmitterGroupNames": ["$CONTACTADDRESS1$"], "emergency": false }' $USER11$/calls
+        }
+</code>
+===== Define DAPNET API-URL, username and password =====
+As you see, there are macros ''$USER11$'' to ''$USER13$'' used. They should contain the API-URL, your DAPNET username and password. Define them in the ''resource.cfg'':
+<code>
+$USER11$=http://dapnet.db0sda.ampr.org:8080
+$USER12$=dl1abc
+$USER13$=VERYSCECRETPASSWORD
+</code>
+If you don't have HAMNET access to dapnet.db0sda.ampr.org, use ''http://hampager.de/api'' without port (default 80 is right) or use your own DAPNET Core's API.
+===== Setup contacts =====
+Edit ''contacts.cfg'' and add the pager subscriber as set in DAPNET and the notification commands:
+<code>
+define contact{
+        contact_name                    dh3wr
+        alias                           Ralf Wilke
+        service_notifications_enabled   1
+        host_notifications_enabled      1
+        service_notification_period     24x7
+        host_notification_period        24x7
+        service_notification_options    w,u,c,r
+        host_notification_options       d,r
+        service_notification_commands   notify-service-by-email,notify-service-by-pager
+        host_notification_commands      notify-host-by-email,notify-host-by-pager
+        email                           spam@myemail.cl
+        pager                           dh3wr
+        address1                        dl-nw
+        }
+</code>
+The ''pager'' entry defines the subscriber on DAPNET, the ''address1'' defines the transmitter group. Remember to add the commands just created.
+{{:icons:warning.png?nolink |}}{{ :icons:warning.png?nolink|}}Attention: In order to minimize traffic on the DAPNET, please select a transmitter group just big enough to fulfill your requirements. Not whole Europe wants to be informed, that you disk space is below 10%.
+===== Assign the contact to the host or service =====
+Either use the template or define at each host and service the contacts you want to notify.
+<code>
+define host{
+        name                            generic-host-rwthafu    ; The name of this host template
+        notifications_enabled           1       ; Host notifications are enabled
+        event_handler_enabled           1       ; Host event handler is enabled
+        flap_detection_enabled          1       ; Flap detection is enabled
+        failure_prediction_enabled      1       ; Failure prediction is enabled
+        process_perf_data               1       ; Process performance data
+        retain_status_information       1       ; Retain status information across program restarts
+        retain_nonstatus_information    1       ; Retain non-status information across program restarts
+        check_command                   check-host-alive
+        max_check_attempts              10
+        notification_interval           0
+        notification_period             24x7
+        notification_options            d,u,r
+        contacts                        rwthafu,dh3wr
+        register                        0       ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!
+        }
+</code>
+===== Example =====
+This is how the result looks like:
