The 6 Best PostgreSQL Performance Monitoring Tools in 2024

PostgreSQL, a highly esteemed free and open-source relational database management system, is often compared favorably to commercial database products. Some even assert that PostgreSQL, developed by Michael Stonebraker, a Turing Award laureate, surpasses them in numerous ways. Regardless of these comparisons, the primary function of any database, including PostgreSQL, is to store data. Given that data is frequently an organization’s most valuable asset, monitoring databases becomes a crucial task for administrators. Accordingly, a good PostgreSQL monitoring tool, like SolarWinds Database Performance Analyzer, PRTG Network Monitor, SQL Sentry, and Idera Diagnostic Manager For SQL Server, are often employed to ensure optimal performance and data integrity.

Best PostgreSQL Monitoring Tools

The main point of monitoring PostgreSQL databases is to ensure that the data they hold is available whenever it is needed and that their performance—i.e. how fast they respond to queries—remains within acceptable parameters. Today, we’re having a look at a few of the best PostgreSQL performance monitoring tools.

We’ll start off by briefly explaining what PostgreSQL is, where it is coming from, and how it came to be. After all, it can only help to know a bit more about what we’re trying to monitor. Then, we’ll specifically discuss the monitoring of PostgreSQL databases. We’ll learn how database servers should be considered in their entirety and that the best monitoring will not only include the actual database software but also the underlying operating system and hardware. We’ll then get to the core of this post as we introduce the best PostgreSQL performance monitoring tools we could find and give you a brief review of each one.

PostgreSQL In a Nutshell

PostgreSQL claims to be the most advanced open-source database. It’s probably more than just a marketing thing, though. It is truly at par with the most powerful commercial databases available. Also known as Postgres, the free and open-source relational database management system (RDBMS) emphasizes extensibility and technical standards compliance. It is designed to handle a range of workloads, from single machines to data warehouses or Web services with many concurrent users. Furthermore, it is the default database for macOS Server and is also available for Linux, FreeBSD, OpenBSD, and Windows.

PostgreSQL evolved from the Ingres project at the University of California, Berkeley. As a matter of fact, the PostgreSQL name was originally just Postgres, and it stood for post-Ingres. It was later changed to PostgreSQL to better reflect its SQL standard compliance. So, back in 1982, Michael Stonebraker, the leader of the Ingres team, left Berkeley to make a proprietary version of Ingres only to return a few years later in 1985 and began a post-Ingres project to address the problems with contemporary database systems that had become increasingly clear during the early 1980s. Recognizing his accomplishments, Stonebraker was granted the Turing Award in 2014 for these and other projects and the techniques they pioneered.

About Monitoring PostgreSQL Databases

Since PostgreSQL is, before all, a standard SQL database, monitoring it is no different from monitoring any other SQL database. The primary goal of PostgreSQL database monitoring is, more than anything, ensuring that data is available when it is needed. A database and the data it contains can be somewhat of an abstract concept. It is, however, made of concrete elements. A solid PostgreSQL monitoring tool, therefore, must always ensure that all those elements—including both hardware and software components—are working and operating within their normal range.

The most basic element of a PostgreSQL server—or any database server, for that matter—is the actual server it runs on, hardware and operating system included. Like any server, there are many operational parameters worth monitoring on a PostgreSQL server. For example, CPU load, available memory, or processor core temperature are all interesting parameters. Monitoring a server running a PostgreSQL database instance is, from a hardware perspective, exactly the same as monitoring any other server.

The underlying operating systems are another element that is worth monitoring. Regardless of what operating system your PostgreSQL server is running on, there are several important parameters to be monitored, such as disk space or disk usage, for example. And just like hardware monitoring, the OS-level monitoring of a PostgreSQL server is not different from that of any other server.

The last thing that needs monitoring is the actual PostgreSQL server instance. By that, I mean the Relational Database Management System software. In its simplest expression, a PostgreSQL server is just another program running on a server. The most basic monitoring, then, is to ensure that this specific program and/or its associated service(s) are running at all times. However, many PostgreSQL performance monitoring tools go further than that. Some, for instance, will check the structure of databases, while some will measure their response time. A PostgreSQL server has several handfuls of parameters that can be monitored to your benefit.

The Best Tools For Monitoring PostgreSQL Databases

We’ve probed the market for the very best PostgreSQL performance monitoring tools and found a wide variety of products. Thanks to PostgreSQL standards adherence, any SQL-compliant monitoring tool should have no problem monitoring a PostgreSQL database. We’ve done our best, as we often do, to include different types of tools on our list. While some are simpler SQL monitoring tools, others are full-featured tools that will monitor every possible parameter and even analyze the structure of your databases, potentially identifying trouble spots.

1. SolarWinds Database Performance Analyzer (FREE TRIAL)

SolarWinds is one of the best-known makers of network and system administration tools and offers a premium PostgreSQL monitoring tool. With a broad array of tools covering almost every topic, many administrators have at least heard of the company. Its flagship product, the Network Performance Monitor, consistently scores among the best network bandwidth monitoring tools. The company is also famous for its free tools, each addressing a specific need of network administrators.

The SolarWinds Database Performance Analyzer (DPA) monitors and analyzes your PostgreSQL database instances or any SQL-compliant database.

SolarWinds Database Performance Analyzer

The SolidWinds PostgreSQL monitoring tool’s easy-to-use interface will assist you in finding issues quickly and easily. But as good as it is a troubleshooting tool (and it is great), it’s also an excellent monitoring tool. Its main screen lets you visualize database instances, wait times, query advice, CPU (with warning and critical alerts), memory, disk, and sessions. The trend dashboard of any specific database instance shows you in a graphical format the total wait times (or your choice of average or typical day wait times) for users over the course of a month, with each color representing an individual SQL statement. This gives you a visually appealing representation of which statement takes the longest to run.

There are so many features in the SolarWinds Database Performance Analyzer that we could write a whole post about it. For now, let’s have a look at some of the most significant.

Single Point Of Monitoring For All Your Databases

The SolarWinds Database Performance Analyzer works with PostgreSQL databases (of course) as well as most major databases, including Microsoft SQL Server, Oracle, MySQL, DB2, and ASE. It also supports physical, on-premises servers, Virtual Machines (running under Vmware or Hyper-V) and cloud-based installations.

Highly Scalable

The tool lets you monitor as many database instances as you need. The software easily scales from one to a thousand database instances. You just need to upgrade the license.

Monitoring Of All Active Sessions

The tool’s native polling engine records everything that’s happening within your database instances with no additional load to the database itself and without requiring a local monitoring agent. This dramatically reduces—if not eliminates—the risk that the tool could impact the databases’ performance.

Tracking, Monitoring, And Analysis Of Database Components

This tool automatically correlates queries, users, files, plans, objects, wait times, storage, and date/time/hour/minute to accurately discover and diagnose problems on the fly.

Database Tuning Advice

The SolarWinds Database Performance Analyzer can give you sound advice for tuning individual database instances to make sure they run at their peak performance. The tool will analyze all parameters of an instance and recommend a course of action to optimize certain queries or even whole database instances.

Prices for the SolarWinds Database Performance Analyzer start at $1,275 and vary according to the number and type of database instances to monitor. If you want to try the product before purchasing it, a fully functional 14-day trial version is available.

2. PRTG Network Monitor

It is built on a clever sensor-based architecture where various sensors allow for different types of monitoring. This tool can monitor anything there’s a sensor for. You can think of sensors as add-ons, although, in the case of this tool, they’re already built-in. Pre-configured database sensors are available out of the box. Most database engines are supported with specific sensors, including PostgreSQL, Microsoft SQL Server, MySQL, and Oracle. The tool will let you monitor the execution time of a SQL query by measuring the time taken from the moment the connection is established to the end of the connection. It will let you clearly see how your databases perform under pressure.

PRTG PostgreSQL Sensor

The PRTG Network Monitor lets you pick from several client user interfaces. There’s a Windows enterprise console, an Ajax-based web interface, and mobile apps for Android, iOS, and Windows Phone. The tool is known to be one of the quickest and easiest to install, with Paessler claiming you could start monitoring within 2 minutes. While our experience shows that it could take longer than that, it is still a very quick and easy installation process.

One of PRTG’s best features—and one of the reasons why it is so quick and easy to install—is its auto-discovery engine, which will scan your network and automatically recognize a wide range of devices and systems, creating appropriate sensors from predefined device templates. The tool also has a map feature that will let you create custom maps with your monitoring data superimposed, offering a unique way of displaying it. When it comes to alerts, PRTG is highly flexible and customizable. The mobile client apps allow you to get push notifications directly to your device.

  1. This is an extremely poorly researched article. Many of the tools you mention (SQL Sentry, Idera Diagnostic Manager, Red Gate SQL Monitor, SQL Power Tools) specifically do not have any support whatsoever for PostgreSQL, and the first 3 of those support only Microsoft SQL Server . 30 seconds of reading about each of those tools on their respective vendors’ websites would have revealed that.

    Being a DBA is hard enough especially for folks who are new to it. Please stop making it harder by being lazy and providing bad information.
