-# Nagios Failover #
-PHP script to help setting up Nagios with failover hosts. The whole idea of this
-script is to run in a cronjob on the failover host. When the remote, default,
-Nagios host goes down, the script will stop touching a "check file" to update 
-it's timestamp. If the remote Nagios is down for more than the predefined number 
-of seconds, the script activates the local Nagios notification. See the flow
-chart in this directory for more information on how the scripts works.
-
-## Usage ##
-Change the variables at the top of the script to suit your environment. Then
-place the script in a crontab (root for example, or someone with Nagios
-permissions) and let it run for example every fourth minute. If the $maxAge in
-the script is 1200 seconds (20 minutes) and the script is being run every fourth
-minute, then the check can fail 5 times (5x4=20) before activating the local
-Nagios notifications.
-
-## Misc thoughts ##
-Nowadays I only disable notifications on the failover hosts. I used to disable
-both host checks, service checks and notifications. Over the years this has
-turned out to generate a lot of false alarms. The false alarms are generate when
-the failover host for example disables it's checks after being active when a
-hosts being monitored where experiencing problems. The checks might than have
-stopped in a soft state with lets say 3/4. When the failover host is then once
-again activating it's checks, it's starts from this state (3/4) and if something
-then, for example, a flaky internet connection makes it fail one more time it
-has reached a hard state and an alarm is being sent.
-Another problem might be if a host or service was flapping the last time the
-failover Nagios was active and then had it's host and service checks disabled.
-The next time the failover Nagios is activated, the host/service which was
-flapping, is now still considered being in a flapping state, even tough this
-might have been two years ago, and thus preventing any alarms until the flapping 
-state goes away.
-For these reasons I now let the failover host run both host and service checks
-even when no failover is necessary.
-When the main Nagios then goes down, the failover Nagios has an up-to-date
-accurate state of all the hosts and services being monitored.
