InterSystems ObjectScript code Profiler

This project, is aimed at enhancing the visibility and understanding of command execution in InterSystems IRIS. It allows users to run any given command and dynamically generates an execution tree that traces the command line-by-line. Additionally, it collects and displays critical metrics for each line, including execution time, enabling a deeper understanding of performance considerations.

Features

• Line-by-line execution and tracking of InterSystems commands.
• Dynamic generation of an execution tree visualizing the command's flow.
• Collection of metrics including execution time for each line.
• Intuitive UI to view executed code, collected metrics, and delve into the execution stack.
• Switch betwen executions on the same stack level.

Installation

objectscript zpm "install zprofile"

Usage

Important note, that the execution takes much longer (hundreds times) under analyzis than without it

To build an execution report, run command like this, put a target command as a first parameter. This command has to be called from the terminal, it's the only way it can get trace, due to the limitation of ZBreak command used in the project

objectscript Do ##class(caretdev.zprofile.main).Trace("Do ##class(Some.Class).Method()")") Do ##class(caretdev.zprofile.main).Trace("Do Some^Routine")

Go to http://localhost:8773/zprofile/index.html (change the port to a correct one)

Select the execution report

On this page, will be shown the code of the first executed method, and it's possible to dive lower by the stack by clicking on arrow down, or return back by stack with arrow up, return back by stack is also available from the the menu.

The last line on any stack level, shows the total for each metric through execution, and cells has a gradient filled by the percentage of the value comparing to the total value.

It is possible to select which columns to display, to help select columns total values shown in the dialog too.
