Monitor your CPU usage in your Dart application

When building a Dart 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 Dart 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 Dart 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 Dart. 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.

Setting up LogSnag

1. Sign up for a free LogSnag account.
2. Create your first project from the dashboard.
3. Head to settings and copy your API token.

Dart 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.

var headers = {
  'Content-Type': 'application/json',
  'Authorization': 'Bearer YOUR_API_TOKEN'
};
var request = http.Request('POST', Uri.parse('https://api.logsnag.com/v1/log'));
request.body = json.encode({
  "project": "my-saas",
  "channel": "status",
  "event": "High CPU Usage",
  "description": "CPI usage has been over 90% for the last 5 minutes",
  "icon": "🚨",
  "notify": true
});
request.headers.addAll(headers);

http.StreamedResponse response = await request.send();

if (response.statusCode == 200) {
  print(await response.stream.bytesToString());
}
else {
  print(response.reasonPhrase);
}
