The best PostgreSQL monitoring tools

Our methodology for selecting PostgreSQL monitoring tools

We reviewed the market for PostgreSQL monitoring software and analyzed the options based on the following criteria:

  • An overview of statistics for all database instances and drill-down detail for statistics on each instance
  • Live measurements of database response times
  • A demonstration of indexing problems within each PostgreSQL instance
  • Recommendations on SQL query optimization
  • An examination of server resource utilization by each database instance
  • A free trial that offers a no-cost assessment period
  • Value for money in a package that delivers a good set of tools that will repay its purchase price

1. Datadog PostgreSQL Performance Monitoring (FREE TRIAL)

Datadog PostgreSQL Monitoring

Datadog is a SaaS platform that includes system monitoring tools. The Datadog Infrastructure module has a specialist integration that allows it to monitor PostgreSQL databases. The monitor will track the operating throughput of the RDBMS and help spot inefficient queries that are gobbling up resources.

Key Features:

  • Cloud-based
  • AI-driven assessments
  • Infrastructure monitoring
  • Autodiscovery
  • Query profiling

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.


  • Cloud-based SaaS product allows monitoring with no server deployments or onboarding costs
  • Can monitor both internally and externally giving network admins a holistic view of their PostgreSQL accessibility
  • Supports auto-discovery that builds network topology maps on the fly
  • Changes made to the network are reflected in near real-time
  • Allows businesses to scale their monitoring efforts reliably through flexible pricing options


  • Would like to see a longer trial period for testing

Analysis tools in the SaaS platform enable you to identify inefficient queries and code and optimize them. 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.

  • Postgres database monitoring
  • Service and server monitoring
  • Root cause analysis

By combining information from all of the sensors in the Site24x7 package you get a better idea of which element in the full system stack is causing responses to slow or services to hang or fall over. As Postgres is a back-end service, performance issues with databases would show up first in a user-facing system because problems with the database will cause response problems elsewhere.

The database monitoring service in Site24x7 is able to watch the responses of the database itself and drill down further to correlate PostgreSQL activity with the availability of supporting services.

The Site24x7 package includes a series of performance expectation thresholds and if one of those is breached anywhere, it will receive an alert, which you can choose to receive by email, SMS, or voice message. By scrolling through the alerts in the Site24x7 console, you will identify which of the batch was raised first, thus immediately seeing where the problem began.


  • Performance thresholds across all monitoring services
  • Monitor Postgres databases on any platform
  • Get live monitoring of performance above, within, and beneath databases
  • See demand patterns to plan capacity for databases

Sematext Infrastructure Servers

Sematext PostgreSQL Monitoring is part of the Sematext Infrastructure Monitoring package. This system offers network, server, application, and services monitoring and it is particularly strong in monitoring databases. The PostgreSQL monitoring system is an add-on to the base Infrastructure Monitoring unit and it is one of a long list of integrations that can expand the system.

Key Features:

  • Tracks multiple instances
  • Database performance
  • Resource monitoring

The PostgreSQL monitoring add-on provides readouts for all the key database metrics, such as transaction throughput and error rates. If locks occur or if resources run short, the Sematext service will raise an alert. This gives you the option to get on with other tasks and let Sematext gt on with monitoring the normal performance of your Postgres databases.

You still get network, server, and application monitoring from Sematext when you activate the PostgreSQL integration. This means that you can see whether server memory shortages or network congestion is the real cause of any performance problems that you encounter with your databases. Dependency mapping can also show you when your database is the real cause of issues with your user interfaces.


  • Monitors within the database and the services that support it
  • Identifies application dependencies
  • Live performance graphs and historical analysis


  • The service can get expensive if you choose a long data retention period

Sematext Infrastructure Monitoring and the PostgreSQL integration are free to use if you run them to watch over five hosts with only a 30-minute data retention period. More hosts and a long retention period get you into the paid editions. Sematext is a SaaS package but there is an option to run it on your own server as a virtual appliance over Docker. Sematext is available for a 14-day free trial.

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.
