mod_http_admin_api: Ensure freshness of metrics when in manual mode When in manual collection mode, as recommended for Prometheus, collection needs to be triggered manually, or they would be stale, possibly dating from the start of the server. This might vary per metric depending on how and when the metrics are gathered.

summary: Measure process resource use metrics (cpu, memory, file descriptors)
---

Description
===========

This module exposes process resource use metrics similar to those exposed by
default when using a Prometheus client library. Specifically, the following
metrics are exposed:

- CPU use
- Resident set and virtual memory size
- Number of open file descriptors and their limit

This module uses the new OpenMetrics API and thus requires a recent version
of Prosody trunk (0.12+).

Compatibility
=============

  ------- -------------
  trunk   Works
  0.11    Does not work
