mod_measure_modules: Report module statuses via OpenMetrics
Someone in the chat asked about a health check endpoint, which reminded
me of mod_http_status, which provides access to module statuses with
full details. After that, this idea came about, which seems natural.
As noted in the README, it could be used to monitor that critical
modules are in fact loaded correctly.
As more modules use the status API, the more useful this module and
mod_http_status becomes.

Introduction ============ This module allows to load/unload external components after they have been added/removed to a configuration file. It is necessary to explicitly initiate a reload on Prosody either via prosodyctl reload or config:reload(). Example 1: -------- If Prosody has started with this configuration file: ``` {.lua} VirtualHost "example.com" authentication = "internal_plain" Component "a.example.com" component_secret = "a" Component "b.example.com" component_secret = "b" ``` And the file has changed manually or dynamically to: ``` {.lua} VirtualHost "example.com" authentication = "internal_plain" Component "a.example.com" component_secret = "a" Component "c.example.com" component_secret = "c" ``` Then, the following actions will occur if this module is loaded: 1. The component c.example.com will be loaded and start bouncing for authentication. 2. The component b.example.com will be unloaded and deactivated. The connection with it will not be closed, but no further actions will be executed on Prosody. Example 2: -------- If Prosody has started with this configuration file: ``` {.lua} VirtualHost "example.com" authentication = "internal_plain" Component "a.example.com" component_secret = "a" ``` And the file has changed manually or dynamically to: ``` {.lua} VirtualHost "example.com" authentication = "internal_plain" Component "a.example.com" component_secret = "a" VirtualHost "newexample.com" authentication = "internal_plain" Component "a.newexample.com" component_secret = "a" ``` Then, the following actions will occur if this module is loaded: 1. The component a.newexample.com will be loaded and start bouncing for authentication. Note that its respective VirtualHost is not loaded. Bad things may happen. Usage ===== Copy the module folder into your Prosody modules directory. Place the module between your enabled modules either into the global or a vhost section. No configuration directives are needed Info ==== - 0.9, works
