logIntakeUrl	false	https://http-intake.logs.datadoghq.com/v1/input/	You can configure a different endpoint, for instance https://http-intake.logs.datadoghq.eu/v1/input/ if your datadog instance is in the EU.
metricsMaxBatchSize	false	200	Metrics are submitted every 10 seconds in batches of size metricsMaxBatchSize.
logsBatchSize	false	500	Logs are submitted in batches of size logsBatchSize as soon as this size is reached.
sendResultsAsLogs	false	false	By default only metrics are reported to Datadog. To report individual test results as log events, set this field to true.
