Struct Collector 

pub struct Collector {
    pub config: Config,
    /* private fields */
}

Embedded CloudWatch Metrics Collector + Emitter

Use Builder to construct

Example

let metrics = metrics_cloudwatch_embedded::Builder::new()
     .cloudwatch_namespace("MyApplication")
     .init()
     .unwrap();

 metrics::counter!("requests", "Method" => "Default").increment(1);

 metrics
     .set_property("RequestId", "ABC123")
     .flush(std::io::stdout());

Fields

config: Config

Implementations

impl Collector

pub fn new(config: Config, lambda_cold_start_span: Option<Span>) -> Self

pub fn set_property( &self, name: impl Into<SharedString>, value: impl Into<Value>, ) -> &Self

Set a property to emit with the metrics

• Properites persist accross flush calls
• Setting a property with same name multiple times will overwrite the previous value

pub fn remove_property<'a>(&'a self, name: impl Into<&'a str>) -> &'a Self

Removes a property to emit with the metrics

pub fn flush(&self, writer: impl Write) -> Result<()>

Flush the current counter values to an implementation of std::io::Write

pub fn write_single( &self, name: impl Into<SharedString>, unit: Option<Unit>, value: impl Into<Value>, writer: impl Write, ) -> Result<()>

Write a single metric to an implementation of std::io::Write, avoids the overhead of going through the metrics recorder

pub fn take_cold_start_span(&self) -> Option<Span>
