This enables the service to identify whether the problem is caused by insufficient resources, locks, poor indexing, or badly written queries.

The PostgreSQL monitoring dashboard is packed with data visualizations, which you might find a little overwhelming. However, you can set alert thresholds on all of those metrics, so you don’t have to watch the passing metrics on live activities to keep ahead of potential problems.

The Datadog Infrastructure deploys an AI-based system, called Watchdog, which can spot potential problems more accurately than straightforward thresholds because it will combine event metrics to derive potential bottlenecks. The combination of monitoring notification techniques means that you can leave the system to monitor your PostgreSQL databases for you.

The dashboard of Datadog can be customized, letting you place all of the information that is important to you in one place. With this, you can create stack views that cover the services that support your PostgreSQL database as well as the RDBMS and query performance.

Who is it recommended for?

The Datadog system is a cloud platform, so it relives the suer of finding a host for the monitoring software. This system can reach out to other cloud systems and your on-premises server to track the performance of your PostgreSQL databases and other applications and resources. This package is suitable for businesses of all sizes.

The analytical capabilities and live monitoring functions of Datadog can be extended by adding on other modules. These include Datadog APM, which performs distributed tracing for Web applications, Network Performance, to check on traffic patterns and network capacity, and Synthetic Monitoring, which monitors the uptime and performance of websites. All Datadog modules are available for 14-day free trials.


Datadog Infrastructure Monitoring is our top pick for a PostgreSQL monitoring tool because it provides general system monitoring from server resources up to user-facing software while also having specialized PostgreSQL monitoring capabilities. The standard package includes systems such as application dependency mapping and server monitoring. However, with the activation of a free integration package, you add on screens and probes that provide detailed monitoring for PostgreSQL database instances. The combination of all of these monitoring systems lets you see inside a running instance and spot performance issues. You will also be able to see whether your databases are damaging the performance of other systems or if underlying services are the root cause of issues.

13. Nagios Core and Nagios XI

Nagios Core and Nagios XI

Nagios Core and Nagios XI are infrastructure monitoring platforms that can measure PostgreSQL performance metrics. The software can monitor PostgreSQL database availability, database size, table size, cache ratios, and more. There is also a range of Nagios plugins for monitoring PostgreSQL. For example, the check_pgactivity plugin allows you to view the connectivity, streaming replication lag, database hit-ratio, index bloat, and more.

Key Features:

  • Choice of Free or Paid Versions: Suits a range of budgetary needs.
  • Plugin Expandability: Customizable with a variety of plugins.
  • Comprehensive Resource Monitoring: Tracks both performance and resources.

Why do we recommend it?

Nagios Core and Nagios XI are free (Core) and paid (XI versions of the same package. Both versions provide full-stack monitoring for networks, servers, and applications and both are able to monitor PostgreSQL database instance performance. The advantage of these systems is that they give you root cause analysis if problems arise.

Nagios Core is a free but more limited version of Nagios XI. Nagios XI has the advantage over the two because it has a web-based GUI and other convenient features like monitoring wizards to make configuration easier. If budget is a priority then Nagios Core is the obvious choice but if you want a more convenient monitoring experience then you should opt for Nagios XI.

Who is it recommended for?

Small businesses will like Nagios Core because it is free to use. However, it doesn’t have a proper interface and you will need to match it up with a front end, such as Kibana. That is quite a technical task. Larger businesses will go for Nagios XI, which has a full user interface and a professional support package.


  • Transparent Open-Source Tool: Offers visibility and community support.
  • Configurable Interface: Tailored alerting and monitoring options.
  • Cross-Platform Support: Runs on both Windows and Linux systems.


  • Complex Setup: Can be challenging to install and configure.
  • Limited Support in Free Version: Professional support mainly in paid version.

Nagios XI starts at a price of $1,995 (£1,601) for the Standard Edition which includes configuration wizards and advanced reporting. The Enterprise Edition costs $3,495 (£2,806) with capacity planning reports and audit logging. You can download the free trial.

Choosing a PostgreSQL tool for you

Out of all the tools on this list, SolarWinds Server & Application Monitor, Paessler PRTG Network Monitor, and Datadog APM are our top picks. Each tool has something unique to offer. AppDynamics is also highly rated based on its deep-visibility, where as SolarWinds Server & Application Monitor offers a detailed but more accessible user experience.

On the other hand, PRTG Network Monitor strikes the balance between a low price tag and a high-value monitoring experience. If you want to go the open-source route then PGadmin is great if you want to mix performance monitoring with administration as well.

PostgreSQL Monitoring FAQs

What should I monitor with PostgreSQL?

Performance monitoring of PostgreSQL should cover query performance (read and write volume and speed), buffer cache metrics (cache hits and disk access), infrastructure usage (server load), transaction statistics (number of commits, locks, ongoing report of live sessions and connections), and replication performance (speed and success of replication and checkpoint statistics).

How do I perform a performance tuning in PostgreSQL?

The main limits on PostgreSQL performance will be hitting shared memory limits or delays in interacting with the hard drive. Check those factors first before adjusting the DBMS settings. For fine tuning, look at the following settings: max_connections, commit_delay, max_fsm_pages, fsync, shared_buffers, effective_cache_size, work_mem, random_page_cost.

How much RAM does PostgreSQL need?

The minimum RAM required to install and run PostgreSQL is 2 GB. Ultimately, RAM requirements will depend on the data volumes accessed by your users and performance speed requirements.

How much data can PostgreSQL handle?

There is no limit to the amount of data a PostgreSQL database can handle. Categorize data volumes into storage and access transactions when planning resources for the database.
