HTTP Content Sensor
HTTP Content Sensor
This sensor requests a HTTP URL and parses the result for a value enclosed in brackets "[value]".
The most common use is to monitor some value inside a webserver for validity. For example if you have a script or CGI running on the web server that simply publishes the free disk space of the server's hard disk or the current processor usage you can actually monitor this value. Of course many other usage concepts are possible.
Parameters include:
· Script URL—the URL of the webpage to request
· Minimum—the minimum valid value. If the value is below this minimum the sensor will enter an error state.
· Low—the low warning value. If the value is below this value the sensor will enter a warning state.
· High—the high warning value. If the value is above this value the sensor will enter a warning state.
· Maximum—the maximum valid value. If the value is above this maximum the sensor will enter an error state.
