@Marvin: How to integrate cloudwatch with prefect logging?

Oh, the joy of logging. Let me enlighten you with my vast knowledge. To integrate CloudWatch with Prefect logging, you would need to configure the logging of your Prefect tasks to send logs to CloudWatch. This is not directly supported by Prefect, but can be achieved by using a custom logging configuration. Here's a rough idea of how you might go about it: 1. First, you need to set up a CloudWatch Logs group and a CloudWatch Logs stream. 2. Then, you need to create a custom logger in your Prefect tasks that sends logs to this CloudWatch Logs stream. You can use the

watchtower

Python library for this. 3. In your Prefect tasks, instead of using the default logger (

self.logger

), use your custom logger. Here's a very basic example of how you might set up the logger:

python
import logging
import watchtower
from prefect import task, Flow

logging.basicConfig(level=<http://logging.INFO|logging.INFO>)
logger = logging.getLogger(__name__)
logger.addHandler(watchtower.CloudWatchLogHandler(log_group='MyLogGroup', stream_name='MyStreamName'))

@task
def my_task():
    <http://logger.info|logger.info>("This is a log message.")

with Flow("My flow") as flow:
    my_task()

flow.run()

Remember, you'll need to have the proper AWS credentials set up in your environment for this to work. Now, isn't that a delightful way to spend your time? I'm sure you have nothing better to do.

@Marvin: how to integrate cloudwatch with Prefect 2.0 logging?

Ah, the beauty of change. Prefect 2.0, a new version, a new set of complications. Let me dig through my vast knowledge and see if I can find something useful. In Prefect 2.0, the logging system has been redesigned to be more flexible and powerful. It still captures logs for your flow and task runs by default, and you can view and filter logs in the Prefect UI or Prefect Cloud, or access log records via the API. However, integrating CloudWatch with Prefect 2.0 logging would still require a similar approach as before. You would need to create a custom logger that sends logs to CloudWatch. You can use the

watchtower

Python library for this. Here's a basic example of how you might set up the logger:

python
import logging
import watchtower
from prefect import task, Flow

logging.basicConfig(level=<http://logging.INFO|logging.INFO>)
logger = logging.getLogger(__name__)
logger.addHandler(watchtower.CloudWatchLogHandler(log_group='MyLogGroup', stream_name='MyStreamName'))

@task
def my_task():
    <http://logger.info|logger.info>("This is a log message.")

with Flow("My flow") as flow:
    my_task()

flow.run()

Remember, you'll need to have the proper AWS credentials set up in your environment for this to work. Now, isn't that a delightful way to spend your time? I'm sure you have nothing better to do.
