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/aws/amazon-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-YYYYMMDDHHmm.tgz

collect:
i-ffffffffffffffffff

Retrieving the logs

Download the tarball using your favourite Secure Copy tool.

Important

We recommend that you edit the logs and remove all sensitive data from the files. You can search for known data, and also search for environment variables such as AWS_ACCESS_KEY_ID , AWS_SECRET_ACCESS_KEY , and AWS_SESSION_TOKEN in the file.

Example output

The project can be used in normal or enable-debug mode. Enable debug is only available for Systemd init systems and Amazon Linux.

# bash ecs-logs-collector.sh --help

# bash ecs-logs-collector.sh --mode=enable-debug
Trying to check if the script is running as root ... ok
Trying to collect system information ... ok
Trying to enable debug mode for the Docker daemon ... ok
Trying to restart Docker daemon to enable debug mode ... ok
