Our friends at ART+COM just released two of their HiveMQ plugins to the public. They are available on Github and may be useful to many MQTT deployments that need to utilize HTTP as an information channel.
HiveMQ Client Status Plugin
This plugin is unfortunately no longer available at Github.
This plugin exposes a HTTP GET endpoint to retrieve the currently connected and disconnected clients with their respective client identifiers and IP addresses. It is useful if you need to quickly check what clients are connected to the broker.

/clients and returns a HTTP Response like this:
HiveMQ Retained Message Query Plugin
This plugin is available at Github.

An example query could look like this:
A response would look like this:
We hope you like the plugins as much as we do. Let us know in the comments what you think!
