Having monitoring tools will allow you to check if the site is working properly, at many different levels.
One of the basic monitoring systems is to know that the site is active, in addition to small elements of loading speed or response times. Usually, external ping services are used that call your website with some frequency and check that it works and is online, and if the access is fast or slow. In case there is a problem, it usually sends some kind of warning as an alert.
In addition, these services usually have panels in which to be able to analyze in a historical way those times and possible service falls.
In general, the measurement of this data is usually done internally since they mainly affect the services available to the machine. For a WordPress to work at least we need the server with its operating system, the web server, the PHP and the database. In addition, we can have the caching systems. Well, the performance monitoring system analyzes all this.
For example, some common server and operating system data is cpu and memory load, bandwidth consumed or storage space and performance, in the web server part the number of valid and invalid requests and responses that are returned, in PHP memory and execution consumption and in the database the size, the number of queries and those that are slow.
