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: 'Receives HTTP POST request, parses it and relays it into XMPP.'
---

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

Sometimes it's useful to have different interfaces to access XMPP.

This module allows sending XMPP
[`<message>`](https://xmpp.org/rfcs/rfc6121.html#message) stanzas via a
simple HTTP API.

Example usage
-------------

    curl http://example.com:5280/msg/user -u me@example.com:mypassword -H "Content-Type: text/plain" -d "Server@host has just crashed!"

This would send a message to user\@example.com from me\@example.com

Details
=======

URL format
----------

    /msg/ [recipient [@host] ].

The base URL defaults to `/msg`. This can be configured via Prosodys
[HTTP path settings][doc:http].

Authentication
--------------

Authentication is done by HTTP Basic.

    Authentication: Basic BASE64( "username@virtualhost:password" )

Payload formats
---------------

Supported formats are:

`text/plain`
:   The HTTP body is used as plain text message payload, in the `<body>`
    element.

`application/x-www-form-urlencoded`
:   Allows more fields to be specified.

`application/json`
:   Similar to form data.

Which one is selected via the `Content-Type` HTTP header.

### Data fields

The form data and JSON formats allow the following fields:

`to`
:   Can be used instead of having the receiver in the URL.

`type`
:   [Message type.](https://xmpp.org/rfcs/rfc6121.html#message-syntax-type)

`body`
:   Plain text message payload which goes in the `<body>` element.

with a very similar API.
