mod_measure_process: Report the enforced limit
The soft limit is what the kernel actually enforces, while the hard
limit is is how far you can change the soft limit without privileges.
Unless the process dynamically adjusts the soft limit, knowing the hard
limit is not as useful as knowing the soft limit.
Reporting the soft limit and the number of in-use FDs allows placing
alerts on expressions like 'process_open_fds / process_max_fds >= 0.95'

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
