Main features:
-

andenvironment
-
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 setSAMPLE_DEBUG_LOG_RATE
to0.05
