mod_rest: Catch and log errors in callback promise chain From the code it looks like it should be possible to reply to an error stanza, but it did not. Turns out I was saved by my local developer mode module which throws errors if an attempt is made to create an errror reply to an error stanza. However nothing collects this error from the promise, so all I got was confusion.

summary: HTTP Host Status Check
...

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

This module exposes serves over HTTP the information collected by [mod\_host\_status\_check] and
[mod\_host\_status\_heartbeat] in a convenient format for automated monitoring tools.

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

[mod\_http\_status\_check] relies on Prosodys HTTP server and mod\_http for
serving HTTP requests. See [Prosodys HTTP server
documentation][doc:http] for information about how to
configure ports, HTTP Host names etc.

Simply add this module to modules\_enabled for the host you would like to serve it from.

There is a single configuration option:

``` {.lua}
    -- The maximum number of seconds that a host can go without sending a heartbeat,
    -- before we mark it as TIMEOUT (default: 5)
    status_check_heartbeat_threshold = 5;
```

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

Works with Prosody 0.9.x and later.
