mod_rest: Restore 'kind' property in JSON-mapped objects The datamapper schema has no 'kind' field, instead handling it as a top-level property of the currently unused <xmpp> element and doing this early dispatch on the top level element name. This puts the field back into the output JSON.

summary: Implementation of the Prometheus protocol
...

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

This module implements the Prometheus reporting protocol, allowing you
to collect statistics directly from Prosody into Prometheus.

See the [Prometheus documentation][prometheusconf] on the format for
more information.

[prometheusconf]: https://prometheus.io/docs/instrumenting/exposition_formats/

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

mod\_prometheus itself doesn’t have any configuration option, but it
requires Prosody’s [internal statistics
provider](https://prosody.im/doc/statistics#built-in_providers) to be
enabled.  You may also want to change the default collection interval
to the one your statistics consumer is using.

```lua
statistics = "internal"
statistics_interval = 15 -- in seconds
```

::: {.alert .alert-warning}
**NOTE:** Make sure to put the statistics variables in the global section of
the configuration, **not** in a `VirtualHost` or `Component` section.  You can
use `prosodyctl check` if you are unsure and want to check your configuration.
:::

See also the documentation of Prosody’s [HTTP
server](https://prosody.im/doc/http), since Prometheus is an HTTP
protocol that is how you can customise its URL.  The default one being
http://localhost:5280/metrics
