JabberIqStats improperly handles the incoming packet (from s2s):

<iq to="tigase.org" id="H_971" from="jabberworld.stats@jabber.ru/comp" xmlns="jabber:client" type="get">
    <query xmlns="http://jabber.org/protocol/stats">
        <stat name="users/total"/>
        <stat name="users/online"/>
    </query>
</iq>

and generates incorrectly addressed query:

wojciech.kapcia@tigase.net commented 3 years ago

As per :

In most cases the http://jabber.org/protocol/stats would be tied to the component or servers admin JID so that only that JID may query the statistics however there are advantages to having a three tier system where some statistics are available to all JIDs, some to an arbitrary JID listed in the configuration file and all available to the listed admin JID. As the first case can be emulated by the second I propose that when implemented the http://jabber.org/protocol/stats namespace is configured to use the three tier method of authorizing queries.

Currently we don't have any list of stats levels that we could leverage. What's more, even locally for admin user the plugin does't work. Given, that we have abundance of ways to retrieve the statistics (ad-hoc, JMX, etc) and this plugin hasn't been used I decided to disable it. It could be fixed in the future, but this is low priority.
