Monitor your Postgres downtime in your Ruby application

Postgres is a robust, relational database commonly used in Ruby applications to persist and query data. It is a great tool with many features, making it an excellent choice for small and large applications.

However, just like any other database, Postgres is susceptible to downtime caused by various reasons. For example, your database instance might go down due to hardware failure, network issues, misconfiguration, or several other reasons. When this happens, chances are that your application will not be able to continue working as expected, causing significant issues such as failing requests and slow performance. In severe cases, it can cause data loss.

Therefore, it is crucial to monitor the status of your database and take immediate action when something is not functioning as expected. Fortunately, LogSnag makes it trivial to track such events as database downtimes and failures. LogSnag is a simple and powerful event tracking tool that allows us to log whenever we encounter an unexpected behavior in our applications.

For example, in the case of Postgres, 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.
