[WIP] mackerel-lambda-agent

A monitoring agent of Mackerel for AWS Lambda.

This is AWS Lambda Extensions provided as AWS Lambda Layers.

NOTE: This is experimental and not suitable for production use.

• Deploy layer with AWS SAM CLI.

$ sam build
$ sam deploy --guided

• Set up the layer for Lambda functions which you want to monitor on Mackerel.
• Configure Mackerel API key as MACKEREL_API_KEY in the Lambda functions environment variables.

Note

• AWS Lambda Extensions runs on the same execution environment as Lambda functions. So it can impact function performance.
• Following are overhead estimations;
  • CPU overhead : ? (Should not so heavy)
  • Memory overhead : ~70MB (Working on decreasing)
  • Duration time overhead: ~1msec
