10 Best PostgreSQL Monitoring Tools in 2023
PostgreSQL is an enterprise-ready feature-rich database. It has been in development since the 80'. PostgreSQL was created at the Berkeley Computer Sciences Department at the University of California. It is an advanced, open-source relational database system supporting both SQL (relational) and JSON (non-relational) querying.
Benefits of using PostgreSQL
- Data types - thanks to its perpetual development and ambitions to be the most advanced open-source database system, PostgreSQL supports various data types such as documents, primitives, geometry, structures, and more.
- Data integrity - PostgreSQL avoids invalid or orphan records by providing consistency and integrity while storing data, thanks to constraints and regulating data.
- Performance - PostgreSQL performance is due to parallelization of reading queries, powerful indexing methods, or Multiversion concurrency control.
- Damage control, recovery, and reliability - Apart from standard practices like backups, PostgreSQL offers one of the highest levels of reliability for your stored data, thanks to sophisticated replication options.
- Support and extensibility - PostgreSQL offers almost limitless extensibility and a broad selection of data types.
- Text search and international characters set support - Postgres supports the majority of international character sets and enables full-text search to speed up the querying. The search is also case and accent insensitive if needed.
- Support of non-relational data: Support for JSON, XML, Hstore, or Cstore is one of the most forward-leaping updates Postgre got.
- Open source license - you can't over deploy PostgreSQL. The open-source license allows you to scale your database infrastructure as you see fit and is mostly based on the results of database monitoring.
PostgreSQL use cases
- Financial industry - Thanks to its full ACID compliance, PostgreSQL is ideal for Online Transaction Processing workloads. On top of that, thanks to integrations with mathematical software such as Matlab or R, it provides a highly capable and powerful analytical database.
- Government GIS data - Thanks to PostGIS integration, PostgreSQL offers a solution to process geometric data in various data. PostGIS is strictly standard-compliant and represents the standard-maker in the Open Source GIS community.
- Manufacturing - PostgreSQL implementation can speed up innovation and growth via customer-centric processes and optimization of supply chain performance. In industrial manufacturing, you can't afford any downtimes, so you need a reliable database solution.
- Web technology and NoSQL workloads - PostgreSQL cooperates with all modern web frameworks like Python's Django, node.js, Hibernate, Ruby on Rails, PHP, and more, and thanks to PostgreSQL's replication features, website projects can be easily scaled out according to your operational needs.
- Scientific data - Research, experiments, and other projects will generate terabytes of data that need to be stored efficiently but at the same time securely and consistently. PostgreSQL offers a broad array of analytical tools and capabilities alongside the SQL engine, which make processing big amounts of data easier. You can also extend your PostgreSQL database by writing your own aggregation functions or creating a custom business logic.
The Best PostgreSQL monitoring tools and software in 2023
PostgreSQL is without a doubt a data storing solution and it can only benefit from integration with a reliable monitoring tool. Let’s take a look at the best PostgreSQL monitoring tools in 2023.
Logtail allows you to collect logs from PostgreSQL databases using Vector. Configuration takes no more than 5 minutes and is done basically in 3 steps. Logtail runs on ClickHouse, which ensures its significantly higher performance and funds efficiency compared to Elastic stack-based solutions.
