This module measures the number of connected clients per identity.
It requires mod_cache_c2s_caps to be loaded on each VirtualHost to provide the data identifying a user’s client.
With the plugin installer in Prosody 0.12 you can use:
sudo prosodyctl install --server=https://modules.prosody.im/rocks/ mod_measure_client_identities
For earlier versions see the documentation for installing 3rd party modules
