What updates last activity

By default marker plugin will only update last activity information on presence stanza. It’s possible to control whether <presence/> and/or <message/> should update with respective options:

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

Those settings will cause updating last activity information for both <message/> and <presence/> stanzas
