 vger's vhost parameter is set (-v), so we'll have to create one or more directories within gemini's home directory, -i (directory index) is also set, so creating an index.gmi is not mandatory.
 
+# Basic monitoring
+
+The following miniamlistic script can be used to check for capsule availability in Nagios/Icinga/Shinken/Etc., assuming gnutls is installed:
+
+```
+#!/bin/sh
+TLS_CLIENT="/usr/local/bin/gnutls-cli -p 1965"
+
+errorOutput=$(echo -n  "gemini://$1/\r\n" | ${TLS_CLIENT} $1 2>&1 > /dev/null)
+errorCode=$?
+if [ $errorCode -gt 0 ]
+then
+  echo "ERROR: ${errorOutput}"
+  return 2
+else
+  echo "OK: capsule responding"
+  return 0
+fi
+```
