Feature Request: Server Status Page

[triska]

Analogous to library(http/http_log), please consider providing library(http/http_status).

This library could gather and display status information about the running server.

I would like to include it simply via:

:- use_module(library(http/http_status)).

:- http_handler('/my-server-status', http_status, []).

possibly with additional security options.

Then, when I visit /my-server-status, it would display, much like mod_status:

• number of workers serving requests
• number of idle worker
• status of each worker, the number of requests that worker has performed and the total number of bytes served by the worker
• total number of accesses and byte count served
• time the server was started/restarted and the time it has been running for
• averages giving the number of requests per second, the number of bytes served per second and the average number of bytes per request
• current percentage CPU used by each worker and in total by all workers combined
• current hosts and requests being processed
• ...

Issues like https://github.com/SWI-Prolog/packages-ssl/issues/25 will become much easier to track down with such a provision.

Thank you!
