In a detailed tutorial, the process of sending logs from Amazon's Elastic Container Service (ECS) to Loki, a log aggregation system from Grafana Labs, is explored, aiming to enhance performance and reduce costs. The guide outlines using AWS's log router, Firelens, to forward logs and metadata from workloads to a Loki instance, enabling consolidated log queries through Grafana. It details the setup of an ECS cluster using Fargate, the creation of a task definition involving a Firelens log router, and a sample application to generate logs. The tutorial advises configuring a task definition's log driver to use awsfirelens for log forwarding and includes steps for creating a service to run tasks, emphasizing the need for proper subnet and security group configuration to ensure connectivity and log visibility. Additionally, it highlights the use of log labels to filter and explore logs within Grafana, suggesting further exploration of the LogQL query language for more advanced log analysis.
