This module provides an implementation of XEP-0502 (MUC Activity Indicator) for Prosody.
To enable it, load it on a MUC host, for example:
"chat.domain.example" "muc"
Component = { "muc_activity" } modules_enabled
When this module is loaded, it will expose the average number of messages per hour for all public MUCs. The number is calculated over a 24 hour window.
Note that this module may impact server performance on servers with many MUCs.
With the plugin installer in Prosody 0.12 you can use:
sudo prosodyctl install --server=https://modules.prosody.im/rocks/ mod_muc_activity
For earlier versions see the documentation for installing 3rd party modules
