ECS Logs Collector

This project was created to collect Amazon ECS log files and Operating System log files for troubleshooting Amazon ECS customer support cases.

The following functions are supported:

• Collect Operating System logs
• Collect Operating System settings
• Collect Docker logs
• Collect Amazon ECS agent Logs
• Enable debug mode for Docker and the Amazon ECS agent (only available for Systemd init systems and Amazon Linux)
• Create a tar zip file in the same folder as the script

Usage

Run this project as the root user:

# curl -O https://raw.githubusercontent.com/awslabs/ecs-logs-collector/master/ecs-logs-collector.sh
# bash ecs-logs-collector.sh

Confirm if the tarball file was successfully created (it can be .tgz or .tar.gz)

#ls collect*
collect-i-ffffffffffffffffff.tgz

collect:
i-ffffffffffffffffff

Retrieving the logs

Download the tarball using your favourite Secure Copy tool.
