AWS users can now forward metrics from key AWS services to different endpoints, including Datadog, via Amazon Kinesis Data Firehose with low latency using CloudWatch Metric Streams. This feature allows for up to an 80 percent reduction in latency compared to using GetMetricData API calls. By integrating CloudWatch Metric Streams with Datadog, teams can obtain comprehensive visibility into their AWS services' health and performance through low-latency metrics and logs. The integration process involves setting up a Kinesis Data Firehose delivery stream and linking it to a CloudWatch Metric Stream for data ingestion from specified AWS services. This enables users to monitor key AWS services such as ELB, RDS, ElastiCache, and more with significantly lower latency, allowing them to identify issues quickly and assess the effectiveness of deployed fixes.
