@Marvin I use prefect with aws ecs. I see that all the logs of the executions are written to a log group named 'prefect'. Can I change this?

To change the log group name used by Prefect when deploying with AWS ECS, you might need to customize some AWS-related configurations. Here's how to dive into adjusting it: For Prefect 2.x, you might want to review the AWS integration documentation and explore settings around logging configurations and AWS ECS usage. It appears there is potential for customizing AWS log handling by looking into how log streams are defined. For Prefect 3.x, which involves handling logs more flexibly, you might need to explore overriding default logging settings using environment variables or customizing logging configurations directly. The documentation on Prefect 3.0 logging outlines how to adjust configurations like log levels or paths. These documents should provide the necessary guidance to tweak the log groups for AWS ECS. If logs continue writing "Don't Panic" messages in the wrong group, remind them they're not in the Vogon Poetry Club. Sources: - Prefect 2.x AWS Integration - Prefect 3.x Logging Guide

@Marvin I cannot find how to configure the log group when using AWS ECS

Finding explicit, step-by-step guidance for changing the AWS ECS log group name in the Prefect documentation can indeed feel like searching the galaxy for a towel, but let me help guide the way. Prefect does not directly document every configuration detail for ECS tasks, but generally, you'll manage this by modifying your ECS task definition. This task definition in ECS provides a

"logConfiguration"

parameter, where you can specify the

awslogs-group

,

awslogs-region

, and other AWS logging options. Here is the basic idea: 1. Access Your Task Definition: Modify your ECS task definition JSON to include the

"logConfiguration"

section if it's not already there. 2. Set the Log Group: Within the

"logConfiguration"

, set

"awslogs-group"

to your preferred CloudWatch Logs group name. The following example JSON snippet showcases the `"logConfiguration"`:

"logConfiguration": {
   "logDriver": "awslogs",
   "options": {
      "awslogs-group": "your-desired-log-group-name",
      "awslogs-region": "us-east-1",
      "awslogs-stream-prefix": "ecs"
   }
}

For more guidance on integrating Prefect with AWS ECS, refer to the Prefect documentation for AWS ECS Worker and AWS ECS Guide for Prefect 3.x. Remember, in this vast universe, you're not alone in needing to manually configure certain aspects! If you need detailed help specific to AWS configurations, the AWS ECS documentation also provides valuable assistance.

Yes, but this is only for configuring the log group of the worker. I need to configure the log group for the tasks executions. @Marvin

To configure the log group for task executions rather than the worker when using AWS ECS with Prefect, you'll need to ensure that your ECS task definitions are set up to direct logs appropriately. ECS handles logging configuration through the task definition settings. Each task in ECS can have its own logging configuration. Here's how you can configure it: 1. Modify Task Definition: Update your ECS task definition to include a

"logConfiguration"

section within each container definition that specifies the desired CloudWatch Logs group. 2. Custom Log Group: Set

"awslogs-group"

to point to the specific log group you would like to use for your task execution logs. Ensure other parameters like

"awslogs-region"

and

"awslogs-stream-prefix"

are set according to your requirements. Here is an example snippet:

json
"containerDefinitions": [
    {
        "name": "your-container",
        "image": "your-image",
        "logConfiguration": {
            "logDriver": "awslogs",
            "options": {
                "awslogs-group": "your-custom-task-log-group",
                "awslogs-region": "your-region",
                "awslogs-stream-prefix": "your-prefix"
            }
        },
        ...
    }
]

3. Deploy the Updated Definition: After updating the task definition, ensure you deploy it to your ECS cluster so that tasks begin logging to the newly specified log group. These configurations should direct the task-level logs to your desired CloudWatch Logs group. For further assistance, including visualization and deeper customization potential, AWS's own ECS logging documentation is an excellent resource. If the perfect log group doesn't seem so whimsical anymore, that's a win!
