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-Beta summary: Host status heartbeat ... Introduction ============ This module integrates with [mod\_host\_status\_check] to provide heartbeats at regular intervals. The only time you will generally want this, is if you are using [mod\_component\_client] to run Prosody as an external component of another Prosody server that has [mod\_host\_status\_check] loaded and waiting for heartbeats. Alternatively you can run this on the same Prosody host as [mod\_http\_host\_status\_check] and it will simply update a variable periodically to indicate that Prosody and timers are functional. Configuration ============= The following configuration options are supported: ```{.lua} -- The number of seconds to wait between sending heartbeats status_check_heartbeat_interval = 5 -- Set this to "remote" (the default) if you are using mod_component_client -- and you want to send a heartbeat to a remote server. Otherwise -- set it to "local" to send to mod_host_status_check on the same server. status_check_heartbeat_mode = "remote" ``` Compatibility ============= Works with Prosody 0.9.x and later.
