Monitoring one IPCheck instance with another instance of IPCheck

Esta pagina no esta disponible en Español. Rogamos su comprension.

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
