It automates the process of retrieving Lambda metrics using the AWS SDK, calculates costs based on metrics like memory usage, invocations, and execution time, and generates a detailed cost report in a CSV file.\n\n# How to Use\n\nThe script requires access to an AWS account in the specified region. This can be achieved by setting up environment variables.\n\n```\nexport AWS_ACCESS_KEY_ID=•••••\nexport AWS_SECRET_ACCESS_KEY=•••••\nexport AWS_REGION=us-east-1\n```\n\nNext, clone the repository and install the dependency.\n\n```\ngit clone git@github.com:meap/lambda-costs.git\ncd lambda-costs/\nnpm install\n```\n\nDefine the period (by months) for which you want to get metrics in the costs.js file. And run the command:\n\n```\nnpm run start\n```\n\n# Output\n\nThe output is in CSV format and can be easily imported into Google Sheets. Here is an example of the output. \n\n| FunctionName | MemoryAllocatedMB | EphemeralStorageMB | Invocations | DurationMilliseconds | InvocationCostUSD | DurationCostUSD | StorageCostUSD | TotalCostUSD |\n|:---------------|--------------------:|---------------------:|--------------:|-----------------------:|--------------------:|------------------:|-----------------:|---------------:|\n| Owl | 4096 | 3072 | 2863583 | 24020100000 | 0.572717 | 1601.34 | 540.451 | 2142.37|\n| Kangaroo | 6144 | 3072 | 45838 | 468853000 | 0.009168 | 46.8854| 10.5492| 57.44|\n| Lion | 2048 | 512 | 909772 | 222943000 | 0.181954 | 7.4314| 0 | 7.61|\n| Zebra | 3072 | 512 | 343025 | 99898100 | 0.068605 | 4.9949| 0 | 5.06|\n| Dolphin | 1024 | 512 | 286866 | 221931000 | 0.057373 | 3.6988| 0 | 3.76|\n| Fox | 128 | 512 | 2910858 | 396841000 | 0.582172 | 0.8268| 0 | 1.41|\n| Fox2 | 256 | 512 | 439937 | 89945100 | 0.087987 | 0.3748| 0 | 0.46|\n| Eagle | 512 | 512 | 308730 | 38817400 | 0.061746 | 0.3235| 0 | 0.39|\n| Wolf | 128 | 512 | 1033464 | 75264300 | 0.206693 | 0.1568| 0 | 0.36|\n| Tiger | 512 | 512 | 7916 | 35873400 | 0.001583 | 0.2989| 0 | 0.30|\n| Shark | 256 | 512 | 36314 | 14437600 | 0.007263 | 0.0602| 0 | 0.07|\n| Lion | 128 | 512 | 239206 | 4662100 | 0.047841 | 0.0097| 0 | 0.06|\n| Panda | 256 | 512 | 9243 | 11347500 | 0.001849 | 0.0473| 0 | 0.05|\n| Wolf | 256 | 512 | 17194 | 9805070 | 0.003439 | 0.0409| 0 | 0.04|\n| Elephant | 256 | 512 | 13223 | 6913890 | 0.002645 | 0.0288| 0 | 0.03|\n| Penguin | 256 | 512 | 3534 | 7307320 | 0.000707 | 0.0304| 0 | 0.03|\n| Kangaroo | 256 | 512 | 20642 | 2920700 | 0.004128 | 0.0122| 0 | 0.02|\n| Rabbit | 256 | 512 | 8515 | 2815730 | 0.001703 | 0.0117| 0 | 0.01|\n| Deer | 128 | 512 | 8526 | 4349520 | 0.001705 | 0.0091| 0 | 0.01|\n| Giraffe | 128 | 512 | 8525 | 4252260 | 0.001705 | 0.0089| 0 | 0.01|\n| Leopard | 256 | 512 | 6485 | 1627210 | 0.001297 | 0.0068| 0 | 0.01|\n| Bear | 256 | 512 | 802 | 751782 | 0.00016 | 0.0031| 0 | 0.00|\n| Giraffe | 256 | 512 | 193 | 760083 | 0.000039 | 0.0032| 0 | 0.00|\n| Dolphin | 256 | 512 | 194 | 345630 | 0.000039 | 0.0014| 0 | 0.00|\n| Shark | 1024 | 512 | 92 | 56241 | 0.000018 | 0.0009| 0 | 0.00|\n| Elephant | 128 | 512 | 197 | 236965 | 0.000039 | 0.0005| 0 | 0.00|\n| Deer | 256 | 512 | 53 | 108903 | 0.000011 | 0.0005| 0 | 0.00|\n| Tiger | 128 | 512 | 821 | 142713 | 0.000164 | 0.0003| 0 | 0.00|\n| Koala | 256 | 512 | 48 | 56567 | 0.00001 | 0.0002| 0 | 0.00|\n| Zebra | 128 | 512 | 6 | 15816 | 0.000001 | 0.0000| 0 | 0.00|\n| Leopard | 128 | 512 | 2 | 3872 | 0 | 0.0000| 0 | 0.00|\n| Panda | 256 | 512 | 0 | 0 | 0 | 0 | 0 | 0.00|\n| Eagle | 256 | 512 | 0 | 0 | 0 | 0 | 0 | 0.00|\n| Hawk | 256 | 512 | 0 | 0 | 0 | 0 | 0 | 0.00|\n| Owl | 256 | 512 | 0 | 0 | 0 | 0 | 0 | 0.00|\n| Rabbit | 1024 | 512 | 0 | 0 | 0 | 0 | 0 | 0.00|\n\n# License\n\nThe MIT License.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmeap%2Flambda-costs","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmeap%2Flambda-costs","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmeap%2Flambda-costs/lists"}
