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'

summary: JSON Encodings for XMPP
...

Introduction
============

This plugin encodes XMPP as JSON. This is an implementation of
[XEP-0295: JSON Encodings for
XMPP](http://xmpp.org/extensions/xep-0295.html).

Simply loading this module makes Prosody accept JSON on C2S streams
(legacy XML clients are still supported).

For BOSH, it requires mod\_bosh be loaded, and JSON should be directed
at the `/jsonstreams` HTTP path.

JSON for S2S isn't supported due to the lack of a discovery mechanism,
so we have left that disabled to stay compatible with legacy XML
servers.

Configuration
=============

Just add `"json_streams"` in your config's global `modules_enabled`
list, for example:

    modules_enabled = {
        ...
        "json_streams";
    }

Strophe.js plugin
=================

We also developed a [JSON streams
plugin](http://prosody-modules.googlecode.com/hg/mod_json_streams/strophe.jsonstreams.js)
for the popular [strophe.js](http://code.stanziq.com/strophe) library.

Just include it like this after including the strophe library, and your
strophe-based client will be speaking JSON:

    <script type="text/javascript" src="strophe.jsonstreams.js"></script>

Be sure to set the HTTP path to `/jsonstreams`. No other changes are
required.
