@dazn/lambda-powertools-pattern-obfuscate v1.29.0

lambda-powertools-pattern-obfuscate

A pattern that helps you follow our guidelines around logging and monitoring. With added ability to obfuscate personal fields.

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-obfuscated-logging middleware with passed obfuscation filters

• 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
