This module logs the conversation of chatrooms running on the server to Prosody's archive storage. To access them you will need a client with support for XEP-0313: Message Archive Management or a module such as mod_http_muc_log.


First copy the module to the prosody plugins directory.

Then add "mam_muc" to your modules_enabled list:

Component "" "muc"
modules_enabled = {

mod_mam_muc needs an archive-capable storage module, see Prosodys storage documentation for how to select one. The store is called "muc_log".


Logging needs to be enabled for each room in the room configuration dialog.

muc_log_by_default = true; -- Enable logging by default (can be disabled in room config)

muc_log_all_rooms = false; -- set to true to force logging of all rooms

-- This is the largest number of messages that are allowed to be retrieved when joining a room.
max_history_messages = 20;


trunk Works best
0.10 Works partially
0.9 Does not work
0.8 Does not work

Prosody trunk (after April 2014) has a major rewrite of the MUC module, allowing easier integration. Without this (0.10), some features do not work, such as correct advertising and join/part logging.
