Monitor MySQL downtime in your C application

MySQL is used commonly when building C as it is a robust, relational database that makes it easy to go from zero to production in no time. In addition, it is a great database with many features, making it an excellent choice for small and large applications.

However, like any other database or software, MySQL is susceptible to issues and downtimes caused by various internal and external factors. For example, connectivity issues, hardware failures, misconfiguration, lack of resources, and many other reasons can cause our MySQL instance to go down and stop working as expected. Thankfully, many services these days take care of hosting and managing MySQL instances for us, making it easy to focus on building our applications. Yet, it is still crucial to monitor the status of our database and take immediate action when something needs to be fixed as expected.

Here at LogSnag, we have been working on that to make it easy for developers to monitor their products and take immediate action when something is not working as expected. LogSnag is a simple yet powerful event-tracking tool that allows us to log anything that happens in our applications, from user actions to database status and downtimes. It creates a single source of truth for all that occurs in the product and provides a number of features to make it easy to manage and monitor our events.

For example, in the case of using MySQL with C, we usually set up periodic checks to ensure that our database is up and running and monitor its performance, disk, and memory usage. If we encounter any issues, such as increased disk usage, slow performance, or downtime, we log the event using LogSnag. It then notifies our team immediately and allows us to take immediate action.

In addition, LogSnag provides a powerful insights dashboard that allows us to monitor the status of our database, its performance, uptime, memory usage, and any other metric that we want to track, making it easy to monitor the health of our database.
