CFTracker: Memory, Apps, Sessions

CFTracker is a CFC for ColdFusion (7/8) which provides methods for accessing the following information:

• Names of all active applications
• Get the application scope keys for any active application
• Get values from any application scope (CF8 Only) without changing the last accessed time
• Application details (time alive, last accessed, idle timeout, expiry status)
• Names of all sessions or per application sessions
• List of keys for any session scope
• Get values from any session (CF8 Only) without changing the last accessed time
• Session information (time alive, last accessed, idle timeout, expiry status)
• ColdFusion Memory information (free, allocated, free allocated, used, maximum allocatable)

Planned additions

There is a setMaxInactiveInterval method for application / session scopes but I’ve been unable to use it so far without triggering the last accessed time to update. Anyone with some Java reflection knowledge could probably work it out, *hint* *hint*.

Usage example

<cfscript>
 cfcTracker = CreateObject('component', 'tracker').init();
 apps = cfcTracker.getApplications();
 sess = cfcTracker.getSessions(apps[1]);
</cfscript>
