I needed something to measure performance of sections of code, possibly sections spanning multilpe templates. I needed it to report in a helpful way. So I knocked together Daves Tick Counting Machine (tm).
It enables you to drop 2 lines of code in with existing code to start performance measuring (first line=start, 2nd lin=stop, like a stopwatch).
It gives you a nice sequential, nested output at the end. And it lets you display the results either on screen, to a log file, or both.
Here's the code: -
In application.cfm: -
<cfset request.tcm=createObject("component","DavesTickCountingMachine").init(enabled=true,outputToScreen=true,outputToLog=false)>
To start/stop monitoring: -
<cfset request.tcm.toggleCounter("Counter Name")>
To view output: -
<cfoutput>#request.tcm.report()#</cfoutput>
DavesTickCountingMachine.cfc: -

Simple.
