Monitoring one IPCheck instance with another instance of IPCheck

The system status URL can be used to easily monitor an instance from a copy of IPCheck Server Monitor running on another system. See the sample content of such a status page below.

This way you can be notified of an IPCheck system fails. Simply create an Advanced HTTP sensor, enter the URL of your System Status page (e.g. http://ipcheckserver/status?pass=815686003E9D4BDB8D8520B34545627C) and put the word '_ERROR' (without the quotes) into the HTML may not include field.

As long as IPCheck runs fine the sensor will show an UP status, as soon as IPCheck discovered a problem internally.

You can even create several of these sensors monitoring the following strings:

  •  CPULOAD_ERROR
  •  WEBSERVER_ERROR
  •  HEARTBEAT_ERROR
  •  DISKSPACE_ERROR
  •  PROBE_ERROR
  •  ADMINDEP1_ERROR
  •  ADMINDEP2_ERROR

All these measurement points also have a warning state that you may also want to monitor for. You can put the word '_WARNING' (without the quotes) into the HTML may not include field and you will be notified whenever a warning shows up - or you can monitor the following specific strings:


  •  CPULOAD_WARNING
  •  WEBSERVER_WARNING
  •  HEARTBEAT_WARNING
  •  DISKSPACE_WARNING
  •  PROBE_WARNING
  •  ADMINDEP1_WARNING
  •  ADMINDEP2_WARNING

Finally you can also monitor the other way round by scanning for '_OK' in the HTML of the page - or you can monitor the following specific strings:


  •  CPULOAD_OK
  •  WEBSERVER_OK
  •  HEARTBEAT_OK
  •  DISKSPACE_OK
  •  PROBE_OK
  •  ADMINDEP1_OK
  •  ADMINDEP2_OK
