PM2 Python Library for Process Management

Introduction

This Python library provides a seamless integration with PM2, enabling users to automate the launching and management of processes using PM2 through Python. Designed to cater to developers and system administrators who require a programmable interface to control their processes with the power and flexibility of Python, this library simplifies interactions with PM2, making it more accessible and versatile.

Features

• Easy Process Management: Start, stop, restart, and delete processes with simple Python functions.
• Automatic Process Launch: Automatically launch multiple processes with predefined configurations.
• Real-time Process Monitoring: Retrieve real-time information about process status, CPU, and memory usage.
• Flexible Configuration: Configure processes programmatically, including environment variables, names, and log file locations.
• Event Handling: Listen to and handle PM2 events directly within your Python scripts.

Installation

To install the PM2 Python Library, run the following command:

pip install pm2

Quick Start

To get started with the PM2 Python Library, here's a simple example that demonstrates how to start a process:

from pm2 import PM2, AioPM2
import asyncio

pm2 = PM2()
aiopm2 = AioPM2()


# Sync Methods
def pm2_manager():
    # List all processes
    processes = pm2.list()
    print(processes)

    # Start a process
    pm2.start(
        "your_script.py",
        name="Script-Name",
        extra_args=["-arg1", "value1"],
        name="YourProcessName",
    )
    # Restart a process
    pm2.restart(name="Script-Name")  # or pid=12345 or pm_id=1

    # Stop a process
    pm2.stop(name="Script-Name")  # or pid=12345 or pm_id=1

    # Delete a process
    pm2.delete(name="Script-Name")  # or pid=12345 or pm_id=1


# Async Methods
async def pm2_manager():
    # List all processes
    processes = await aiopm2.list()
    print(processes)

    # Start a process
    await aiopm2.start(
        "your_script.py",
        name="Script-Name",
        extra_args=["-arg1", "value1"],
        name="Script-Name",
    )

    # Restart a process
    await aiopm2.restart(name="Script-Name")  # or pid=12345 or pm_id=1

    # Stop a process
    await aiopm2.stop(name="Script-Name")  # or pid=12345 or pm_id=1

    # Delete a process
    await aiopm2.delete(name="Script-Name")  # or pid=12345 or pm_id=1


# Run the function
pm2_manager()
# or
asyncio.run(pm2_manager())

Replace 'your_script.py', 'Script-Name', and the args as necessary to fit your needs.
