+====== Monitoring of Unipager Transmitters on the Unipager itself ======
-Ein entsprechendes Plugin für die Websocket-Schnittstelle kann unter [[https://github.com/rwth-afu/UniPagerNagios|https://github.com/rwth-afu/UniPagerNagios]] heruntergeladen werden.
+===== Overview =====
-Zur Installation mit
+There are three variantes of Nagios plugins available.
+  * Solution with JSON Status output of Unipager directly (since Version 1.0.0)
+  * Websocket based with C++ programm
+  * Websocket based with Python programm
+Also Daniel Dibbets DL6FZ provided a Template for Zabbix. See below for more info.
+If you have already Unipager V 1.0.0 or newer installed, the JSON output solution is highly recommended due to performance issues.
+===== Up-to-date Solution with JSON Output =====
+This approach uses the same ''check_http_json'' Nagios plugin as  [[monitoringnagios|here]]. For further information on installation refere to this site. No ''nagios-nrpe-server'' is needed (although it makes sense to use it for temperature monitoring, disk space, etc.)
+Add to your ''commands.cfg'' the following lines:
+<file>
+# 'check_unipager_connected' command definition
+define command{
+        command_name    check_unipager_connected
+        command_line    /usr/lib/nagios/plugins/check_http_json -H '$HOSTNAME$' -P $ARG1$ -p status -Q "connected,True"
+}
+# 'check_unipager_queue' command definition
+define command{
+        command_name    check_unipager_queue
+        command_line    /usr/lib/nagios/plugins/check_http_json -H '$HOSTNAME$' -P $ARG1$ -p status -w queue,$ARG2$ -c queue,$ARG3$
+}
+</file>
+  * ARG1: Port of the HTTP Server of Unipager, default is ''8073''
+  * ARG2: Number of POCSAG transmissions in queue to be exceeded for status ''warning''
+  * ARG3: Number of POCSAG transmission in queue to be exceeded for status ''critical''
+Create a service description for the new commands:
+<file>
+# Define a service to check if unipager is connected to a Node
+define service{
+        use                             generic-service-rwthafu
+        host_name                       c9000.db0sda.ampr.org
+        service_description             UniPager Connection to DAPNET Core
+        check_command                   check_unipager_connected!8073
+        }
+# Define a service to check if unipager queue is too full
+define service{
+        use                             generic-service-rwthafu
+        host_name                       c9000.db0sda.ampr.org
+        service_description             UniPager Queue
+        check_command                   check_unipager_queue!8073!100!150
+        }
+</file>
+The result should be like this:
+{{ ::monitoring:nagios_json_connection_and_queue.png?direct&800 |}}
+===== Websocket Solution =====
+{{:icons:warning.png?direct |}}{{ :icons:warning.png?direct|}}The websocket methods are superseeded by the JSON method. Please use the new one. The following documentation is for historical reasons only.
+Ein entsprechendes Plugin für die Websocket-Schnittstelle kann unter [[https://github.com/rwth-afu/UniPagerNagios|https://github.com/rwth-afu/UniPagerNagios]] heruntergeladen werden. Es gibt 2 Varianten:
+  * C++ Version (Viele Abhängigkeiten)
+  * Pyhton2 Version (Einfache Installation)
+Dazu muss der Nagios NRPE-Server installiert werden.
+<code>sudo apt-get install nagios-nrpe-server</code>
+Zur Installation des Check-Plugins zunächst das Repository herunterladen:
+<code>git clone https://github.com/rwth-afu/UniPagerNagios.git</code>.
+==== C++-Version ====
+Mit

-git clone https://github.com/rwth-afu/UniPagerNagios.git

+==== Pyhton2-Version ====
-<file>
+There is in the same Git-repository a pyhton2 version to do the same. You can find the code in ''python/check_unipager'' . The setup is almost the same as for the C++ version. As this method is overseeded by the JSON approach, there is no further documentation here for the moment.
-# 'check_rustpager' command definition
-define command{
-        command_name    check_unipager
-        command_line    /usr/lib/nagios/plugins/check_unipager -H '$HOSTNAME$' --port $ARG1$
-}

-Dann erstellt man eine Datei in ///etc/nagios3/conf.d// mit z.B. dem Hostnamen //c9000.db0sda.ampr.org.cfg// und dem Inhalt
+==== Generelle Einstellungen für NRPE ====
+Die Datei ''/etc/nagios/nrpe.cfg'' entsprechen anpassen, insbesondere:
+<code>allowed_hosts=127.0.0.1,44.225.x.y</code>
+Die Datei ''/etc/nagios/nrpe.d/check_unipager.cfg'' erstellen mit Inhalt
+<code>sudo nano /etc/nagios/nrpe.d/check_unipager.cfg</code>
+<file>command[check_unipager]=/usr/lib/nagios/plugins/check_unipager -H localhost</file>
+ACHTUNG: Nur bei Zugriff von ''localhost'' aus braucht man ab der Version 0.7.1 von [[unipager|UniPager]] kein Passwort.
+Dann den nagios-nrpe-server neu starten:
+<code>service nagios-nrpe-server restart</code>
+Auf dem Haupt-Nagios-Server kann man dann mit den NRPE-Plugin den Status abfragen. Dazu erstellt man eine Datei in ''/etc/nagios3/conf.d'' mit z.B. dem Hostnamen''c9000.db0sda.ampr.org.cfg'' und dem Inhalt
 <file>
 define host{

+        check_command           check_nrpe_1arg!check_unipager

 Die hostgroup, host_name, alias und IP müssen natürlich angepasst werden. Einmal nagios neustarten und schon wird der Status überwacht.
+===== Zabbix Template for Unipager =====
+Daniel Dibbets DL6FZ provided a template for Zabbix to monitor the unipager program.
+{{ :monitoring:zbx_unipager_template.xml |Download Template here}}
+Items are observed:
+  * Connected
+  * Master
+  * Queue
+  * Version
+  * Calls RX
+  * Calls TX
+Triggers are integrated:
+  * Not Connected
+  * Queue > 500
+  * Queue > 1000
+Data is gathered from Status JSON (http://{HOST.NAME}:8073/status)
+Zabbix will build history and delta information concerning the numberical values.
