Monitor memory usage in your C application

LogSnag is a monitoring service that alerts you when your application is experiencing high memory usage.

A common problem that we often face with C applications is memory leaks and the overall memory usage of our application. This is a significant problem when building applications that we end up deploying to the cloud either as a serverless function, container, or virtual machine. In such cases, memory usage can become a significant problem by slowing down our application, causing it to crash entirely, or increasing costs.

Therefore, monitoring our C application's memory 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. In cases of a performance issue, for example, when the memory usage goes above a certain threshold, say 80 percent, we can take immediate action and fix the problem before it becomes a significant issue.

To do so, we have created LogSnag, a powerful event tracking tool that works seamlessly with C and allows us to track any event in our application in real-time. For example, with LogSnag, we can track our memory usage in real-time and set up a rule to notify our team and us when the memory usage goes above a certain threshold via push notifications. This way, we will always be aware of the performance of our application, and we can take immediate action if needed.

  headers = curl_slist_append(headers, "Authorization: Bearer YOUR_API_TOKEN");
  curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
  const char *data = "{\"project\":\"my-saas\",\"channel\":\"status\",\"event\":\"High Memory Usage\",\"description\":\"Memory usage has exceeded the threshold.\",\"icon\":\"🚨\",\"notify\":true}";
