One common issue arises due to leaking database connections, which in turn degrades the performance of your database. With metrics in place, keep a close eye on connection count. One easy way to do that is by installing the Librato addon to track this data over time. These metrics are tracked and alerted on appropriately. We offer a number of system metrics which are output on your application logs. The first step in understanding the performance of your database is to track various vital metrics, which offer an overall view of your system’s performance.

If your application requires predictable performance and availability, upgrade your database plan.

Essential-tier databases have variable performance characteristics by design.
