Monitor when a user is being rate limited in your C application

LogSnag makes it easy to monitor your C application and to detect when a user is being rate limited.

When building a C application, you often have to deal with throttling. Throttling is a way to limit the number of requests that a user can make to your application. This is a common problem when building applications that are used by a lot of users. For example, let's say you're building a C application that allows users to upload files. You may want to limit the number of files a user can upload to 10 per minute. Again, this is a common problem and a great way to prevent users from abusing your service.

It is important to monitor when a throttle is being hit in your C application. It can signify a problem with your implementation or that a user may be trying to take advantage and abuse your service. Therefore, it's vital to set up a system to properly monitor when the throttle is being hit and let you and your team know when something is wrong.

LogSnag is an excellent tool for this problem as it trivializes tracking events in your C application and monitoring when the throttle is being hit. For example, you can use LogSnag to track an event when a user uploads a file. You can then set up a rule to notify you when a user has uploaded ten files. This way, you will know when a user has reached their limit, allowing you to take further action if needed.

  headers = curl_slist_append(headers, "Content-Type: application/json");
  headers = curl_slist_append(headers, "Authorization: Bearer YOUR_API_TOKEN");
  curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
  const char *data = "{\"project\":\"my-saas\",\"channel\":\"limits\",\"event\":\"User is being rate limited\",\"description\":\"User has uploaded more than the allowed amount of files\",\"icon\":\"⏱\",\"notify\":true}";
  curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data);
  res = curl_easy_perform(curl);
}
curl_easy_cleanup(curl);

C integration details

When designing LogSnag, we aimed to create the most simple yet flexible event tracking tool possible. We wanted to make it easy for developers to integrate with their C applications and to start tracking events in no time.

Today, LogSnag is what we believe to be the next generation of event tracking. It works excellent with C and provides powerful features such as real-time event tracking, cross-platform push notifications, event filtering, user and product journeys, charts and analytics, and much more.

LogSnag provides a free plan to get you started with event tracking, and we can't wait to see how you use it. So please give it a try, and don't hesitate to reach out to us if you have any questions or feedback!
