HTTP Content Sensor Configuration
Questa pagina anchora non esiste in Italiano. Confidiamo nella Vs. comprensione.
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:
- Timeout: If the reply takes longer than this value the request is aborted and an error message is triggered
- Script URL: The URL of the web page to request
- Channel Name: Define a name for the channel (for display purposes only)
- Unit String: Define a unit string for the result (for display purposes only)
- SSL Method: Select a SSL encryption method
- Content: Check this option if you want to monitor any content changes (checksum
based). This can be combined with an 'On Change' notification to notify the user when the resulting webpage changes.
