Last Activity

To lower impact on performance, by default last activity information is persisted to repository less frequently. This can yield slightly less accurate results on installations with multiple cluster nodes with users having multiple resources connected. To get more accurate results you should set persistAllToRepository to true, which will cause all update times to be persisted (please bear in mind that this could cause higher impact on the repository).

'sess-man' {
    'jabber:iq:last-marker' (active: true) {
        persistAllToRepository = true
    }
}
