CPU Profile Summarizer

This tool is designed to summarize CPU profiling data for use in generating dataset prompts, providing insights into function execution times and their impact on CPU usage.

Prerequisites

Before you can use the CPU Profile Summarizer, ensure you have Node.js installed on your system. You can download and install Node.js from https://nodejs.org/.

Installation

No installation is required. Simply clone or download the repository containing the tool to your local machine.

Usage

To use the CPU Profile Summarizer, follow these steps:

1. Open a terminal or command prompt.
2. Navigate to the directory containing the index.js file of the CPU Profile Summarizer.
3. Run the tool using Node.js, passing the path to the CPU profile JSON file as an argument:

node index.js <path-to-cpu-profile.cpuprofile>

Replace <path-to-cpu-profile.cpuprofile> with the actual path to your CPU profile JSON file.

For example:

node index.js profiles/myAppProfile.cpuprofile

The tool will process the CPU profile and generate a summary file in the summaries directory, located in the same directory as index.js. The summary file will be named after the original profile file, with a .summary.jsonl extension.

Output

The tool will return the prompt with the data you will only have to add your question and your answer

{"messages":[{"role":"user","content":"Given the following CPU profile data: <summary generated by the tool> answer the following question: < your question>"},{"role":"assistant","content":"<Here goes the AI response>"}]}

The summary contains the following information:

topSelfTimeFunctions: Functions with the highest self execution times. topTotalTimeFunctions: Functions with the highest total execution times. startTime: The start time of the profiling session, in seconds. endTime: The end time of the profiling session, in seconds.

Each function in the topSelfTimeFunctions and topTotalTimeFunctions lists includes:

functionName: The name of the function. totalTime: The total execution time of the function, in seconds. hitCount: The number of times the function was executed. selfTime: The self execution time of the function, in seconds. url: The URL of the script containing the function. selfTimePercentage: The percentage of the highest self time relative to the total profile duration. totalTimePercentage: The percentage of the highest total time relative to the total profile duration.
