We’d like to get deeper insight into the host, the underlying operating system, and any third-party services used by our application. This allows us to quickly tell whether the network link may be saturated or the processor is running at its limit. Host monitoring We start off with the very first layer: the host itself.

Logs: A log file tells you about an event that has already happened; it is a record of events from software and operating systems. As they are automatically generated by the system, Log files can contain mountains of info, but are only as informative or valuable as the ability to process and understand the data they contain.

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.

For specific information on I/O tuning and balancing, you will find more details in the following document.
