Metrics helper library for AWS Lambda Function
Provides the way to put metrics to the CloudWatch
using EMF
Examples
async fn function_handler(event: LambdaEvent<Request>) -> Result<Response, Error> {
let command = event.payload.command;
let mut metrics = Metrics::new("custom_lambdas", "service", "dummy_service");
metrics.try_add_dimension("application", "customer_service");
metrics.add_metric("test_count", MetricUnit::Count, 10.4);
metrics.add_metric("test_seconds", MetricUnit::Seconds, 15.0);
metrics.add_metric("test_count", MetricUnit::Count, 10.6);
// Prepare the response
let resp = Response {
req_id: event.context.request_id,
msg: format!("Command {}.", command),
};
Ok(resp)
}
Metrics are flushed automatically when the Metrics
object is dropped.
Caller can flush metrics manually by calling flush_metrics
method.
