Can I expose CloudWatch metrics?

Question

I know that you can send metrics from services outside of AWS into CloudWatch to display on dashboards. I'm wondering if the inverse is possible? For example, if I have an EventBridge in AWS, does CloudWatch have an endpoint I can hit to pull Invocation count or other metrics from outside AWS?

Accepted Answer

Yes you can. [Publishing custom metrics](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/publishingMetrics.html) is a great start. Additionally, you can also look into [CloudWatch Metric Steams ](https://aws.amazon.com/blogs/aws/cloudwatch-metric-streams-send-aws-metrics-to-partners-and-to-your-apps-in-real-time/) for a more robust large scale solution.

Answer

Without knowing what kind of custom server this is, I would urge you look at how many of the partner services like [Dynatrace](https://www.dynatrace.com/news/blog/amazon-cloudwatch-metric-streams-launch-partnership/), [Datadog](https://www.datadoghq.com/blog/amazon-cloudwatch-metric-streams-datadog/), [Splunk](https://www.splunk.com/en_us/blog/devops/real-time-observability-splunk-cloudwatch-metric-streams.html). [Sumo Logic](https://www.sumologic.com/blog/aws-partner-cloudwatch-metrics-collection/) etc. consume CW data. The solution is built upon CW pushing metrics to Kinesis Firehose. Firehose can then deliver the payload to variety of destination including [http endpoints](https://docs.aws.amazon.com/firehose/latest/dev/create-destination.html#create-destination-http).
