Prometheus Exporter for AWS clients

Why:

• There are never enough metrics.
• Metrics provided by AWS (usually through CloudWatch) measure server-side latency.

What is:

• a very simple solution to publish several basics metrics (latency, data transferred) while interacting with AWS

How to use it

• The recommended way to use this library is through your build tool.

• The prometheus-exporter-for-aws-clients artifact is published to Maven Central, using the group com.deevvi .

• Latest stable version is 1.0.4.

Therefore,it can be added to your Gradle project by adding the dependencies:

compile "com.deevvi:prometheus-exporter-for-aws-clients:1.0.4"

and in Maven:

<dependency>
    <groupId>com.deevvi</groupId>
    <artifactId>prometheus-exporter-for-aws-clients</artifactId>
    <version>1.0.4</version>
</dependency>

Code example:

MeterRegistry meterRegistry = new SimpleMeterRegistry();
RequestHandler2 prometheusHandler = new PrometheusExporterRequestHandler(meterRegistry, "my-app-name");

AmazonSQSClientBuilder.standard()
        .withCredentials(new SystemPropertiesCredentialsProvider())
        .withRequestHandlers(prometheusHandler)
        .build();

Configuration parameters:

• meterRegistry: Prometheus handler
• metricPrefix: nullable prefix for metrics. Useful in case inside an application, there are multiple clients for the same service created and to distinguish between them.
