GPTtrace 🤖

Generate eBPF programs and tracing with ChatGPT and natural language

Key Features 💡

Interact and Tracing your Linux with natural language, it can tell how to write eBPF programs in BCC, libbpf styles.

example: tracing with Count page faults by process

Generate eBPF programs with natural language

Usage and Setup 🛠

$ ./GPTtrace.py
usage: GPTtrace [-h] [-i | -v | -e TEXT | -g TEXT] [-u UUID] [-t ACCESS_TOKEN]

Use ChatGPT to write eBPF programs (bpftrace, etc.)

optional arguments:
  -h, --help            show this help message and exit
  -i, --info            Let ChatGPT explain what's eBPF
  -v, --verbose         Print the prompt and receive message
  -e TEXT, --execute TEXT
                        Generate commands using your input with ChatGPT, and run it
  -g TEXT, --generate TEXT
                        Generate eBPF programs using your input with ChatGPT
  -u UUID, --uuid UUID  Conversion UUID to use, or passed through environment variable `GPTTRACE_CONV_UUID`
  -t ACCESS_TOKEN, --access-token ACCESS_TOKEN
                        ChatGPT access token, see `https://chat.openai.com/api/auth/session` or passed through
                        `GPTTRACE_ACCESS_TOKEN`

First: login to ChatGPT

• get the Conversion ID from ChatGPT, and then set it to the environment variable GPTTRACE_CONV_UUID or use the -u option. The Conversion ID is the last part of the URL of the conversation, for example, the Conversion ID of https://chat.openai.com/conv/1a2b3c4d-0000-0000-0000-1k2l3m4n5o6p is 1a2b3c4d-0000-0000-0000-1k2l3m4n5o6p(example, not usable).
• get the access token from ChatGPT, and then set it to the environment variable GPTTRACE_ACCESS_TOKEN or use the -t option. see https://chat.openai.com/api/auth/session for the access token.

Use prompts to teach ChatGPT to write eBPF programs

./GPTtrace.py -t

This will use the material in the prompts directory to teach ChatGPT to write eBPF programs in bpftrace, libbpf, and BCC styles. You can also do that manually by sending the prompts to ChatGPT in the Website.

start your tracing! 🚀

For example:

./GPTtrace.py -e "Count page faults by process"

Installation 🔧

./install.sh

Examples

• Files opened by process
• Syscall count by program
• Read bytes by process:
• Read size distribution by process:
• Show per-second syscall rates:
• Trace disk size by process
• Count page faults by process
• Count LLC cache misses by process name and PID (uses PMCs):
• Profile user-level stacks at 99 Hertz, for PID 189:
• Files opened, for processes in the root cgroup-v2
