    lambda-powertools-pattern-basic

    A basic pattern that helps you follow our guidelines around logging and monitoring.

    Main features:

    • configures Datadog metrics namespace using the function name if one is not specified already

    • configures Datadog default tags with awsRegion, functionName, functionVersion and environment

    • applies the @dazn/lambda-powertools-middleware-correlation-ids middleware at a default 1% sample rate

    • applies the @dazn/lambda-powertools-middleware-sample-logging middleware at a default 1% sample rate

    • applies the @dazn/lambda-powertools-middleware-log-timeout middleware at default 10ms threshold (i.e. log an error message 10ms before an invocation actually times out)

    • allow override for the default 1% sample rate via a SAMPLE_DEBUG_LOG_RATE environment variable, to sample debug logs at 5% rate then set SAMPLE_DEBUG_LOG_RATE to 0.05
