Node.js client for Stackdriver Monitoring: Visibility into the performance, uptime, and overall health of cloud-powered applications.

Stackdriver Monitoring: Node.js Client

Node.js idiomatic client for Monitoring.

Stackdriver Monitoring collects metrics, events, and metadata from Google Cloud Platform, Amazon Web Services (AWS), hosted uptime probes, application instrumentation, and a variety of common application components including Cassandra, Nginx, Apache Web Server, Elasticsearch and many others.

Quickstart

Before you begin

1. Select or create a Cloud Platform project.

   Go to the projects page

2. Enable billing for your project.

   Enable billing

3. Enable the Stackdriver Monitoring API.

   Enable the API

4. Set up authentication with a service account so you can access the API from your local workstation.

Installing the client library

npm install --save @google-cloud/monitoring

Using the client library

// Imports the Google Cloud client library
const monitoring = require('@google-cloud/monitoring');

// Your Google Cloud Platform project ID
const projectId = 'YOUR_PROJECT_ID';

// Creates a client
const client = new monitoring.MetricServiceClient();

// Prepares an individual data point
const dataPoint = {
  interval: {
    endTime: {
      seconds: Date.now() / 1000,
    },
  },
  value: {
    // The amount of sales
    doubleValue: 123.45,
  },
};

// Prepares the time series request
const request = {
  name: client.projectPath(projectId),
  timeSeries: [
    {
      // Ties the data point to a custom metric
      metric: {
        type: 'custom.googleapis.com/stores/daily_sales',
        labels: {
          store_id: 'Pittsburgh',
        },
      },
      resource: {
        type: 'global',
        labels: {
          project_id: projectId,
        },
      },
      points: [dataPoint],
    },
  ],
};

// Writes time series data
client
  .createTimeSeries(request)
  .then(results => {
    console.log(`Done writing time series data.`, results[0]);
  })
  .catch(err => {
    console.error('ERROR:', err);
  });

Versioning

This library follows Semantic Versioning.

This library is considered to be in beta. This means it is expected to be mostly stable while we work toward a general availability release; however, complete stability is not guaranteed. We will address issues and requests against beta libraries with a high priority.
