OpenTelemetry Google Cloud Monitoring Exporter allows the user to send collected metrics to Google Cloud Monitoring.

Cloud Monitoring provides visibility into the performance, uptime, and overall health of cloud-powered applications. It collects metrics, events, and metadata from Google Cloud, Amazon Web Services, hosted uptime probes, application instrumentation, and a variety of common application components including Cassandra, Nginx, Apache Web Server, Elasticsearch, and many others. Operations ingests that data and generates insights via dashboards, charts, and alerts. Cloud Monitoring alerting helps you collaborate by integrating with Slack, PagerDuty, and more.

Installation

``bash
npm install --save @opentelemetry/sdk-metrics
npm install --save @google-cloud/opentelemetry-cloud-monitoring-exporter
`

Usage

`js
const { MeterProvider, PeriodicExportingMetricReader } = require("@opentelemetry/sdk-metrics");
const { MetricExporter } = require("@google-cloud/opentelemetry-cloud-monitoring-exporter");

// Create MeterProvider
const meterProvider = new MeterProvider();
// Register the exporter
meterProvider.addMetricReader(
new PeriodicExportingMetricReader({
// Export metrics every 10 seconds. 5 seconds is the smallest sample period allowed by
// Cloud Monitoring.
exportIntervalMillis: 10_000,
exporter: new MetricExporter(),
})
);

// Create a meter
const meter = meterProvider.getMeter("metrics-sample");

// Create a counter instrument
const counter = meter.createCounter("metric_name");
// Record a measurement
counter.add(10, { key: "value" });

// Wait for the metric to be exported
new Promise((resolve) => {
setTimeout(resolve, 11_000);
});
``
