PHP

Good evening.
How is such a state status made like that of VK? vk.com/dev/health.
How is server status data obtained? How are they recorded and where?

Answer 1

A separate service checks the api reference methods.
There are services like https://www.runscope.com/docs/api-testing to implement this, if you don’t want to bother yourself.
