+# Prosody failed encryted S2S communication
+Is a plugin for the monitoring software [Munin](http://munin-monitoring.org) to monitor a [Prosody](http://prosody.im) XMPP server.
+
+The plugins monitors failed encryted server to server (S2S) communication between a remote server and the local server.
+
+Here's an example how how this plugin works: [Prosody failed encrypted S2S communication statistics for jabber.hot-chilli.net](https://www.hot-chilli.net/munin/hot-chilli.net/tethys.hot-chilli.net/loggrep_prosodys2sfails.html)
+
+## Installation and configuration
+It is very simple to install this plugin.
+
+Create symlink:
+
+`ln -s /usr/share/munin/plugins/loggrep /etc/munin/plugins/loggrep_prosodys2sfails`
+
+Create a file */etc/munin/plugin-conf.d/loggrep_prosodys2sfails* (we don't want change the standard file */etc/munin/plugin-conf.d/munin-node* as future updates might want to undo the changes) and put the following into it:
+```
+[loggrep_prosodys2sfails]
+user root
+env.regex_outencfailed outgoing s2s stream .* closed: Encrypted server-to-server communication is required but was not offered
+env.label_outencfailed outgoing S2S encryption failed
+env.regex_inencfailed incoming s2s stream .* closed: Encrypted server-to-server communication is required but was not used
+env.label_inencfailed incoming S2S encryption failed
+env.logfile /var/log/prosody/prosody.log
+env.title Prosody failed encrypted S2S communication
+```
+
+Edit */etc/munin/munin.conf* - in our case we have a Munin host named *tethys.hot-chilli.net*, please add it under the specifications for your own host:
+```
+[tethys.hot-chilli.net]
+    address 127.0.0.1
+    ...
+    loggrep_prosodys2sfails.graph_category prosody
+    loggrep_prosodys2sfails.graph_period minute
+```
+
+Now you need to restart munin-node:
+
+`/etc/init.d/munin-node restart`
+
+That's it. Enjoy!
