PHP-FPM Queue Monitor

A Rust application that monitors PHP-FPM socket queue lengths across Docker containers and sends metrics to AWS CloudWatch.

Overview

This tool replaces the original bash script that monitors PHP-FPM containers. It:

1. Discovers PHP-FPM containers: Scans running Docker containers to find those running php-fpm
2. Collects queue metrics: Uses nsenter and ss commands to check socket queue lengths
3. Sends to CloudWatch: Uses the AWS SDK to send high-resolution metrics to CloudWatch
