Monitor when database goes down in your Ruby application

Almost every Ruby application requires some data persistence. In a good number of cases, we can go by using a simple JSON, CSV, or even a text file to store our data. However, in most cases, we need a more robust solution that can handle a large amount of data and many requests and allow us to perform complex queries.

This is where databases come in. Databases are a great way to store and retrieve data in a structured form. They are also a great way to perform complex queries and scale our application. However, databases can be a complex topic and can be challenging to set up and maintain.

One of the most common problems with databases is that they can go down and become unavailable for various reasons. As a consequence, our Ruby application will fail to work correctly and will not be able to retrieve or store data.

In such cases, it's essential to monitor your database activity and notify you and your team when something is wrong. This way, you can take immediate action and fix the problem before it becomes a significant issue.

Fortunately, LogSnag is an excellent tool for this problem as it trivializes tracking events in your Ruby application and monitoring database outages. With LogSnag, you can easily track your database outages in real-time and notify you and your entire team when something goes wrong.
