Indexes are generally considered to be the panacea when it comes to SQL performance tuning, and PostgreSQL supports different types of indexes catering to different use cases. I keep seeing many articles and talks on “tuning” discussing how creating new indexes speeds up SQL but rarely ones discussing removing them.

Think about items such as general system metrics (for example, CPU utilization, free memory, number of services), the connectivity status, details of our web server, or even more granular in-application tasks like database queries. DNS query time indicates the average response times of DNS requests across the system.

Not all back-end errors affect the user experience, but keeping track of them can prove helpful when tuning your app. Of course, there are also times when the problem lies not with your application but with the user’s connection or network configuration.

A log is a detailed, timestamped record of an event generated by an operating system, computing environment, application, server, or network device. Logs can include data about user inputs, system processes, and hardware states. Optimized system performance. What is log monitoring? Log monitoring vs log analytics.

The concept of Observability isn’t new to monitoring; in a nutshell, it is the state or ability for a system to send information that can be collected and interpreted to understand its overall health or performance. Automatic configuration of application network. Stand-alone observability won’t cut it. Automatic service distribution.
