What does this PR do?
Allow custom metrics to be submitted to CloudWatch Logs, and then be forwarded by Datadog log forwarder. This option can be enabled by setting environment variable
DATADOG_FLUSH_TO_LOG
toTrue
.Motivation
Writting metrics to logs rather than sending to Datadog metric intake endpoint helps avoid adding latencies to the Lambda executions.
Testing Guidelines
Upgrade to the latest version of datadog lambda layer and log forwarder.
