Tips for Effective PostgreSQL Monitoring According to

When the database infrastructure is integrated and running, it is important to understand what is going on at all times. To ensure everything is working properly, ongoing monitoring is needed. This monitoring will also provide an alert if something needs to be changed.

For every database technology, there are numerous things to monitor. Some are specific to the vendor or database engine, or version being used. It is possible to visit this blog link to learn more or to keep reading to learn about Key Metrics for Postgresql Monitoring solutions.

Things to Monitor in PostgreSQL

When monitoring a database node or cluster, there are two main things to consider – the database itself and the operating system. It is necessary to define the metrics and timescale that will be monitored from both sizes and determine how this will be done according to It is important to monitor the metric in context to the system and make sure to look for any alterations on the behavior pattern.

Usually, several tools will be needed to do this effectively. Remember, if one of the metrics is affected, it will likely impact others, which makes troubleshooting issues problematic while impacting performance. Having a quality alerting and monitoring system in place is essential to make this task as simple as possible.

Operating System Monitoring  

A crucial element, which is something that is common to all systems and databases, is to monitor the behavior of the operating system. Some of the top things to keep an eye on are listed here.

CPU Usage

Excessive CPU usage may be problematic if it is not considered usual behavior. If this happens, it is a good idea to find the process or the processes that have generated the problem. If the issue is a database process, you must check what is going on inside the database.

SWAP Usage and RAM Memory

If someone sees a higher value for this metric and nothing has actually changed in the system, it is a good idea to check the database configuration. The parameters such as work_mem and shared_buggers may affect this directly because they define the total amount of memory to use the PostgreSQL database.

Disk Usage

If there is an excessive or abnormal increase in the amount of disk space being used or excessive disk access consumption, it is important to monitor these things. There could be a large number of errors that are logged in the PostgreSQL log file or as a bad cache configuration that may generate an important disk access consumption rather than using memory to process these queries.

Monitoring the PostgreSQL database is not just crucial to see if there is an issue, but also to know if something needs to be changed to improve the performance of the database. This is considered one of the most important things to keep tabs on in any database. Keep this in mind to know why this is important and what it offers businesses. Being informed and knowing what to do are the best ways to ensure the desired results are achieved.
