CloudWatch Monitoring
{{#title:CloudWatch Monitoring Server Configuration: Detailed Technical Documentation}}
Overview
This document details the hardware configuration designed to optimally run and support Amazon CloudWatch agent-based monitoring on a dedicated server infrastructure. This configuration focuses on providing a stable, high-throughput platform for collecting, aggregating, and processing metrics, logs, and events from a large number of monitored instances. It's designed to complement, not replace, AWS-native CloudWatch services, offering a localized, high-volume data processing tier for specific use cases. This allows for near real-time insights and reduced reliance on network latency to the AWS Cloud. This is a dedicated server, not an EC2 instance. The benefits of dedicated hardware include predictable performance and cost control for consistent monitoring workloads.
