# Observability: tools in this layer of The Stack

> Logs, metrics, alarms. 1 tools, from Nicolas Dao's defaults to what he would never use (Cloudless Labs, Sydney).

- Web page: https://cloudlesslabs.com/stack/layers/observability/

## My default

- [Amazon CloudWatch](https://cloudlesslabs.com/stack/aws-cloudwatch/index.md), Logs, metrics and alarms: Good features. Keep it for the logs you watch live and alarm on; send the chatty bulk through Firehose to S3.
