Monitor your CPU usage in your JavaScript application

When building a JavaScript application, we often have to think and deal with performance issues. Performance is a critical aspect of any application and can significantly affect the user experience. One of the most common performance issues for JavaScript applications is when the workload is CPU bound. This means that the application spends most of its time waiting for the CPU to complete a task.

In such cases, monitoring our JavaScript application's CPU usage and setting up a system to track when use goes above a certain threshold is essential. This way, we can always be aware of the performance of our application. Furthermore, in cases of a performance issue, for example, when the CPU usage goes above a certain threshold, we can take immediate action and fix the problem before it becomes a significant issue.

Fortunately, here at LogSnag, we have created a powerful solution for this problem. LogSnag is a powerful, real-time event tracking tool that works seamlessly with JavaScript. With LogSnag, you can set up event tracking for anything you want and monitor things like your CPU usage in real-time. In addition, you can set up a rule to notify you and your team when the CPU usage goes above a certain threshold. This way, you will always be aware of the performance of your application, and you can take immediate action if needed.

JavaScript code snippets

To track your CPU usage, you can use the following code snippet Please don't forget to replace the YOUR_API_TOKEN with your API token and update the project and channel names.

Using JavaScript with Fetch

var myHeaders = new Headers();
myHeaders.append("Content-Type", "application/json");
myHeaders.append("Authorization", "Bearer YOUR_API_TOKEN");

var raw = JSON.stringify({
  "project": "my-saas",
  "channel": "status",
  "event": "High CPU Usage",
  "description": "CPI usage has been over 90% for the last 5 minutes",
  "icon": "🚨",
  "notify": true
});

var requestOptions = {
  method: 'POST',
  headers: myHeaders,
  body: raw,
  redirect: 'follow'
};

fetch("https://api.logsnag.com/v1/log", requestOptions)
  .then(response => response.text())
  .then(result => console.log(result))
  .catch(error => console.log('error', error));

Using JavaScript with jQuery

var settings = {
  "url": "https://api.logsnag.com/v1/log",
  "method": "POST",
  "timeout": 0,
  "headers": {
    "Content-Type": "application/json",
    "Authorization": "Bearer YOUR_API_TOKEN"
  },
  "data": JSON.stringify({
    "project": "my-saas",
    "channel": "status",
    "event": "High CPU Usage",
    "description": "CPI usage has been over 90% for the last 5 minutes",
    "icon": "🚨",
    "notify": true
  }),
};

$.ajax(settings).done(function (response) {
  console.log(response);
});

Using JavaScript with XHR

// WARNING: For POST requests, body is set to null by browsers.
var data = JSON.stringify({
  "project": "my-saas",
  "channel": "status",
  "event": "High CPU Usage",
  "description": "CPI usage has been over 90% for the last 5 minutes",
  "icon": "🚨",
  "notify": true
});

var xhr = new XMLHttpRequest();
xhr.withCredentials = true;

xhr.addEventListener("readystatechange", function() {
  if(this.readyState === 4) {
    console.log(this.responseText);
  }
});

xhr.open("POST", "https://api.logsnag.com/v1/log");
xhr.setRequestHeader("Content-Type", "application/json");
xhr.setRequestHeader("Authorization", "Bearer YOUR_API_TOKEN");

xhr.send(data);
