Ejabberd chat room message count visibility

Question

Users are only seeing messages posted in a group chat for only last two days or so(count is less than 30). Is there a config setting that can control how many messages from the past (or in number) can be shown in a chat room when a user connects to it? In ejabberd.yml I only see a setting max_user_offline_messages under access has a value of 1000 for all. Also mod_muc has a setting access_max_user_messages: max_user_offline_messages

Is there another setting that controls this functionality?

We are using ejabberd version 16.02.79

Answer 1

I guess you refer to the room recent history. The number can be configured with this option:

history_size: Size: A small history of the current discussion is sent to users when they enter the room. With this option you can define the number of history messages to keep and send to users joining the room. The value is an integer. Setting the value to 0 disables the history feature and, as a result, nothing is kept in memory. The default value is 20. This value is global and thus affects all rooms on the service.
