stdin_to_cloudwatch

This tool is intended to process input fromstdin and publish some metrics encoded in the log stream. It looks for log lines that match a certain format and publishes to Cloudwatch metrics. The lines that not match are neither filtered nor altered and are written to stdout. The format for the metrics follows:

{
  "Environ/SomeNamespace": 
    [
      {
        "AMetricName": 2558219, 
        "Units": "Milliseconds",
      }
    ]
}

Possible values for Units are:

"Seconds"|"Microseconds"|"Milliseconds"|"Bytes"|"Kilobytes"|"Megabytes"|"Gigabytes"|"Terabytes"|"Bits"|"Kilobits"|"Megabits"|"Gigabits"|"Terabits"|
"Percent"|"Count"|"Bytes/Second"|"Kilobytes/Second"|"Megabytes/Second"|"Gigabytes/Second"|"Terabytes/Second"|"Bits/Second"|"Kilobits/Second"|"Megabits/Second"|
"Gigabits/Second"|"Terabits/Second"|"Count/Second"|"None"

(Same as put-metric-data units)

Usage

your_script | stdin_to_cloudwatch -i <django|none> -r <region> [-d <DimensionName=DimensionValue>]

Use stdin_to_cloudwatch -h for help.

AWS credentials are managed by boto3, so refer to boto documentation for further information.

Intention

Intention behind this tool is to decouple metrics publishing from the main app. With this tool publishing is a responsibility of infrastructure.
