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'

--- labels: - 'Stage-Alpha' summary: 'Track the status and health of s2s connections' ... Introduction ============ Prosody already gives some insight into current s2s connections, e.g. via the `s2s:show()` command in the console. This will tell you about all current s2s connections. However sometimes this is not enough. For example if an s2s connection fails to establish, it won't show up - you have to go digging through the log file looking for the errors instead. This module maintains a record of recent connection attempts to a remote domain. You can use this module to answer questions such as: - Why did the last connection attempt to `example.com` fail? - When did I last have a successful connection with `example.com`? - Are my s2s connections generally stable? **Note:** At the time of writing, this module is not yet finished, and should be considered a proof-of-concept. # Configuration Just load the module as normal: ``` {.lua} modules_enabled = { ... "s2s_status"; ... } ``` # Compatibility trunk (0.12) and later, e.g. due to [60676b607b6d](https://hg.prosody.im/trunk/rev/60676b607b6d).
