System Probes page
System probes help you evaluate the status of your ColdFusion applications. Like scheduled tasks, they access a URL at a specified interval, but they can also check for the presence or absence of a string in the URL. If the URL contents are unexpected, or if an error occurred while accessing the URL, the probe can send an e-mail alert to the address specified on the System Probes page. The probe can also execute a script to perform a recovery action, such as restarting the server. All probe actions are logged in the logs/probes.log file. The System Probes page also displays the status of each probe.
You use the buttons in the Actions column in the System Probes table to perform the following actions:
|
Action |

|

|

|

Because probes run as scheduled ColdFusion tasks, they will not run if the server on which they are hosted crashes, or if the host web server crashes or otherwise does not respond.
System probes are available in ColdFusion Enterprise Edition only.
