You can publish your own custom metrics in a variety of ways
The example below uses the AWS CLI to publish a metric called throttlecount
under the dimension ServerName,ServerType
to the observabilityworkshop
namespace.
aws cloudwatch put-metric-data --metric-name throttlecount --namespace observabilityworkshop --unit Count --value 156 --dimensions ServerName=DemoServer,ServerType=A1
Open a terminal window and paste the above command and press enter. This should publish the metric to CloudWatch Metrics.
Once completed, go to CloudWatch Metrics which will directly take you to the metric you just published.
