SageWorks CloudWatch

Need Help?

The SuperCowPowers team is happy to give any assistance needed when setting up AWS and SageWorks. So please contact us at sageworks@supercowpowers.com or on chat us up on Discord

The SageWorks framework continues to flex to support different real world use cases when operating a set of production machine learning pipelines. As part of this we're including CloudWatch log forwarding/aggregation for any service using the SageWorks API (Dashboard, Glue, Lambda, Notebook, Laptop, etc).

Log Groups and Streams

The SageWorks logging setup includes the addition of a CloudWatch 'Handler' that forwards all log messages to the SageWorksLogGroup

Individual Streams

Each process running SageWorks will get a unique individual stream.

  • ecs/DashBoard* (any logs from SageWorks Dashboard)
  • glue/* (logs from Glue jobs)
  • lambda/* (logs from Lambda jobs)
  • docker/* (logs from Docker containers)
  • laptop/* (logs from laptop/notebooks)

Since many jobs are run nightly/often, the stream will also have a date on the end... glue/my_job/2024_08_01_17_15

AWS CloudWatch made Easy

Logs in Easy Mode

The SageWorks cloud_watch command line tool gives you access to important logs without the hassle. Automatic display of important event and the context around those events.

pip install sageworks
cloud_watch

The cloud_watch script will automatically show the interesting (WARNING and CRITICAL) messages from any source within the last hour. There are lots of options to the script, just use --help to see options and descriptions.

cloud_watch --help

Here are some example options:

# Show important logs in last 12 hours
cloud_watch --start-time 720 

# Show a particular stream
cloud_watch --stream glue/my_job 

# Show/search for a message substring
cloud_watch --search SHAP

# Show a log levels (matching and above)
cloud_watch --log-level WARNING
cloud_watch --log-level ERROR
cloud_watch --log-level CRITICAL
OR
cloud_watch --log-level ALL  (for all events)

# Combine flags 
cloud_watch --log-level ERROR --search SHAP
cloud_watch --log-level ERROR --stream Dashboard

These options can be used in combination and try out the other options to make the perfect log search :)

Access through AWS Console

Since we're leveraging AWS functionality you can always use the AWS console to look/investigate the logs. In the AWS console go to CloudWatch... Log Groups... SageWorksLogGroup
