Detailed explanation of PostgreSQL database resource monitoring scheme under CentOS system

This article introduces a variety of methods to monitor PostgreSQL database resources on CentOS systems to help you discover and solve potential performance problems in a timely manner.

1. Use PostgreSQL built-in tools and views

PostgreSQL comes with rich tools and views that can be used directly for performance and status monitoring:

  • pg_stat_activity : View the currently active connection and query information.
  • pg_stat_statements : Collect SQL statement statistics and analyze query performance bottlenecks.
  • pg_stat_database : provides database-level statistics, such as transaction count, cache hit rate, etc.
  • pg_stat_bgwriter : Monitors statistics of the background writer (bgwriter), including the number of buffer writes and checkpoints.
  • pg_stat_user_tables : View user table statistics, such as insert, update, and delete times.
  • pg_statio_all_tables : View I/O statistics for all tables, such as the number of reads and writes.
  • pg_stat_replication : Monitors replication status and delay.

2. Lightweight monitoring tool Sampler

Sampler is a lightweight monitoring tool developed based on Go language, which can be easily deployed without additional servers or databases. It can monitor database runtime, traffic, buffer hit rate, transaction commit/rollback rate, as well as server status (load, CPU usage, remaining memory) and connection status.

3. PostgreSQL monitoring based on Zabbix

Zabbix is ??a powerful open source monitoring system. By installing the libzbxpgsql plug-in, you can monitor PostgreSQL. The Zabbix server and proxy need to be configured and monitoring users and templates are created.

4. Datadog cloud monitoring platform

Datadog is a cloud-native monitoring and analysis platform that supports PostgreSQL monitoring. After installing the Datadog agent, you can use real-time performance analysis, custom dashboard, alarm notifications and log management functions.

5. PgAdmin graphical monitoring

pgAdmin is a popular open source PostgreSQL management tool that provides a graphical interface to facilitate monitoring of database performance metrics, such as query plans, tablespace usage and index usage.

6. Integration of custom scripts and monitoring systems

For complex monitoring needs, custom scripts can be written and integrated with monitoring systems such as Nagios and Zabbix to achieve a more flexible and comprehensive monitoring solution.

Choosing the right monitoring method depends on your specific needs and technical capabilities. Through the above methods, you can effectively monitor PostgreSQL database resources to ensure the stable operation of the database.
