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: 'Measure number of daily, weekly and monthly active users' ... Introduction ============ This module calculates the number of daily, weekly and monthly active users - often abbreviated as DAU, WAU and MAU. These metrics are more accurate for determining how many people are actually using a service. For example simply counting registered accounts will typically include many dormant accounts that aren't really being used. Many servers also track the number of connected users. This is a useful metric for many purposes, but it is generally lower than the actual number of users - because some users may only connect at certain times of day. The module defines "activity" as any login/logout event during the time period, and for this it depends on mod_lastlog2 being loaded (it reads the data stored by mod_lastlog2). Each individual user is only counted once. "Daily" means any event within the past 24 hours, "weekly" means within the past 7 days, and "monthly" means within the past 30 days. Details ======= The user count is calculated shortly after startup, and then recalculated hourly after that. Metrics are exported using Prosody's built-in statistics API. There is no configuration for this module. Compatibility ============= Requires Prosody 0.11 or later with mod_lastlog2 enabled.
