Set up an alert for sudden, large changes to the current connection count.

There are two strategies for setting up alerts based on database connection counts: Once that limit is reached no new connections can be created.

Heroku Postgres enforces a connection limit in order to optimize Postgres memory usage and scaling.įor Heroku Postgres plans tier-3 and higher there is a hard limit of 500 connections. The active-connections metric lists the number of established connections to your database. If you get close to maximum size, either upgrade your plan or delete data to stay within plan limits. We recommend setting a warning alert when your database gets to 80% of the allotted size for your plan and a critical alert when it gets to 90% of the allotted size. Set alerts based on your plans limit to give you some advanced notice if you start approaching it. In some cases, we will set an enforcement date when you will be allowed only a single database connection and access will be restricted to READ, DELETE, and TRUNCATE access until the database in back under the plan limit. If your Postgres database grows past the size allotted for your plan, you will receive a warning email with directions on how fix the issue. The db_size metric is the size of the database, including all table and index data, as well as database bloat. The following metrics should have alerts set up to provide meaningful alarms pertaining to database health: db_size

A full list of monitoring add-ons can be found on the Heroku Elements Marketplace. Librato provides ready-made graphs and the ability to set custom alert thresholds for specific metrics. The most effective way to keep track of database metrics is to install a platform monitoring add-on. Understanding and monitoring these metrics will ensure the health of your database as your applications run and scale. Heroku Postgres provides database and server metrics that give information on the status of your instance. Set up metrics monitoring with a platform monitoring tool This article describes how to effectively set up monitoring for your database, including which tools to use and what metrics to look for.

Use monitoring tools to spot problems in advance, respond to incidents quickly, and identify the root cause of issues. Set up metrics monitoring with a platform monitoring toolĪutomated monitoring for your Heroku Postgres database can provide insight into the performance of your app and database.
