Monitoring Key Metrics to Keep Your Postgres Database Healthy

July 18, 2023

Data is a critical asset, and effectively utilizing it depends on your database. It is important to rigorously monitor your Postgres database to ensure continuous availability and optimal performance. Today's complex IT structures require proactive monitoring to prevent issues that could lead to system outages, data loss or other critical issues.

Monitoring improves business effectiveness and efficiency 

Monitoring is key for keeping your database up and running smoothly. An effective database monitoring strategy will enable you to:

1) Maintain Availability – By monitoring your database ecosystem, you can safeguard Postgres availability and protect your revenue and reputation. Metrics such as database availability, database connections, transaction wraparound, Database growth rate, disk usage, database size, wal generation,database backup, and replication will help you ensure data availability.

2) Optimize Your System – Monitoring helps to identify system bottlenecks and other gaps so you can keep your system running seamlessly. For example, all IO Stats parameters, memory usage, heap cache miss ratio, HOT update ratio, and checkpoint rate can help you optimize the system.

3) Identify Performance Problems – By uncovering performance problems related to bloating, slow running queries, table and index statistics or other areas, you can prevent these issues from becoming bigger problems later. Load average, CPU and IO stats, and PGBouncer are useful checks to identify areas of improvement. 

4) Improve Business Processes – Knowing the load, user activity, and other metrics associated with your system helps you to prioritize customer tasks, reporting jobs or downtime. Metrics such as active backends, active connections, and wal production rate can help you improve end user experience.

5) Drive Capacity Planning – Monitoring can help you understand your current system utilization, determine when applications require more disk space, forecast system scaling needs and support your future growth plans. Database size, disk usage, and database folder checks related to wal’s and temp files provide insightful data for planning for future systems.

Often Overlooked Metrics 

With so much going on in your datacenter, we tend to focus on important and urgent metrics. But there are a number of dimensions that are important, perhaps not urgent and so frequently neglected. Measures that can dramatically impact your Postgres database and application should also include monitoring the database ecosystem. For example, Pgbouncer, Pgpool, Postgres distributed, EDB Failover manager, EDB Repr manager, EDB replication manager, and Barman tools.
