  • Allows businesses to scale their monitoring efforts reliably through flexible pricing options

Cons:

  • 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.

EDITOR'S CHOICE

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.

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.
