Code Profiler in ColdFusion Performance Monitoring Toolset

Run Code profiler

The Performance Monitoring Toolset monitors all transactions on a ColdFusion server and captures the response times along with other basic details of a transaction.

The procedure requires recording metrics for all components of a transaction, and thus you have the Code Profiler.

To run the code profiler, click Code Profiler on the left panel.

The tags that are not captured in profiling are: 

  1. cfif
  2. cfelse
  3. cfelseif
  4. cftry
  5. cfcatch
  6. cfset

  1. Choose the server, which needs to be profiled.

  2. Enable the option Memory Profiling.

    The option lets you know the memory consumption and the location of the variable. The field is optional. Enable it if you want to profile memory usage as well.

  3. Choose the profile mode:

    • Application: Specify the name of the application, that needs profiling. Profiling does not capture the data for other applications, which are not added.
    • URL: Specify a URL that needs profiling. Add the URL and make sure that profile check-box is selected. Profiling does not capture the data for other URLs, which are not added.
    • Server: Choose the server that needs profiling.
