+plugins/plugins/check_multiple_host_addresses
+---------------------------------------------
+This script is a first attempt to monitor multi-home and dual-stack (i.e. ipv4
+and ipv6) servers. In my setup a server should only considered availble if it is
+available on all of its primary addresses (i.e. both ipv4 and ipv6). It uses the
+excellent check_multi script to perform multiple a ping check to see if a host
+is available and reports the consolidated status. Using check_multi has the
+advantage that pnp4nagios and other scripting graphing solutions will support
+this solution as well.
+
+Installation is straightforward, after installing the script on your server, add
+the following to your `commands.cmd` configuration file to make it available:
+~~~
+ # 'check-host-alive' command definition for multi-homed/dual-stack servers
+ define command{
+ command_name check-addresses-alive
+ command_line [install_path]/plugins/check_multiplehost_addresses '$HOSTADDRESS$' '$_HOSTADDRESS6$'
+ }
+~~~
+The example above assumes that the IPv6 address of the host is provided as part
+of the host configuration, i.e.:
+~~~
+ define host {
+ ...
+ address 192.168.0.1
+ _address6 fdf8:f340:ab9d:c213::1
+ ...
+ }
+~~~
+To use the script either add ` check_command check-addresses-alive`
+to the specific hosts that should use the check or to the generic host used as
+template.

cgi-bin/nagiosstatus.sh
-----------------------
Very simplistic CGI-BIN script that checkes whether nagios is still running and
still updating its status. It wil always return an HTTP Status 200 (OK) and a
simple text page with one of the following texts:
- - STOPPED - in case the nagios process is not running
- - STALLED - in case the nagios status file has not been updated for 5 minutes
- - OK - when Nagios is running and updated its status file < 5 minutes ago
+ - `STOPPED` - in case the nagios process is not running
+ - `STALLED` - in case the nagios status file has not been updated for 5 minutes
+ - `OK` - when Nagios is running and updated its status file < 5 minutes ago
I wrote this script to be used with an external monitoring system, I use it with
the free subscription from [Pingdom](http://www.pingdom.com) to get alerts when
