Monitoring one IPCheck instance with another instance of IPCheck
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. This way you can be notified if 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 Response 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, it outputs an "XXX_ERROR" string on the status page. This is caught by the sensor which will change to the DOWN state.
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
Most measurement points also can have a warning state that you may want to monitor for. You can put the word “_WARNING” (without the quotes) into the Response 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
