How to view/read the golang echo logs on AWS?

[sriramkp]

The below configuration is just logging the logs to the console:

e.Logger.SetLevel(log.ERROR)
e.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
		Format: `${time_rfc3339_nano} ${remote_ip} ${host} ${method} ${uri} ${user_agent} ${status} ${error} ${latency_human}` + "\n",
	}))

try setting logger.SetOutput(w io.Writer)

Hello,

Is there any better option or best practice that we need to follow regarding logging, when we deploy our service to AWS platform?

Are you using containers? Basically just write to stdout and have container engine do the log forwarding. stdout works for systemd etc services also.

Yes, For time being I am deploying with ElasticBeanstalk by using Multi-container Docker running on 64bit Amazon Linux. Once the user-base increase I want to deploy on the Kubernetes cluster.

You mean to push the docker container logs to AWS CloudWatch?

[aldas]

I am not familiar with AWS CloudWatch but in case of multiple instances you definitively should push logs to some centralized logging system that has some graphical interface for inspecting the logs. Quick googling says that Docker can be configured to send logs to CloudWatch https://docs.docker.com/config/containers/logging/awslogs/

In my own small apps (hosted in small VPSes) I usually write to stdout/stderr in container and Docker sends them to journald and which logs also end up in Graylog instance.

Thankyou so much!, The below docker configuration worked for me on AWS.

"logConfiguration": {
    "logDriver": "awslogs",
    "options": {
        "awslogs-group": "awslogs-service",
        "awslogs-region": "us-west-2",
        "awslogs-stream-prefix": "awslogs-example"
    }
}
