--- labels: - 'Statistics' ... This module provides **public** access to Prosodys [internal statistics][doc:statistics] trough the [XEP-0039: Statistics Gathering] protocol. This is a simple protocol that returns triplets of name, unit and value for each know statistic collected by Prosody. The names used are the internal names assigned by modules or statsmanager, names from the registry are **not** used. # Configuration Enabled as usual by adding to [`modules_enabled`][doc:modules_enabled]: ```lua -- Enable Prosodys internal statistics gathering statistics = "internal" -- and enable the module modules_enabled = { -- other modules "stats39"; } ``` # Usage ## Example Statistics can be queried from the XML console of clients that have one: ```xml C: <iq type="get" to="example.com" id="dTMERjt5"> <query xmlns="http://jabber.org/protocol/stats"/> </iq> S: <iq type="result" to="example.com" id="dTMERjt5"> <query xmlns="http://jabber.org/protocol/stats"> <stat name="cpu.clock:amount" value="0.212131"/> <stat name="cpu.percent:amount" value="0"/> <stat name="memory.allocated:amount" value="8.30259e+06"/> <stat name="memory.allocated_mmap:amount" value="401408"/> <stat name="memory.lua:amount" value="6.21347e+06"/> <stat name="memory.returnable:amount" value="13872"/> <stat name="memory.rss:amount" value="2.03858e+07"/> <stat name="memory.total:amount" value="6.53885e+07"/> <stat name="memory.unused:amount" value="14864"/> <stat name="memory.used:amount" value="8.28773e+06"/> <stat name="/*/mod_c2s/connections:amount" value="0"/> <stat name="/*/mod_c2s/ipv6:amount" value="0"/> <stat name="/*/mod_s2s/connections:amount" value="0"/> <stat name="/*/mod_s2s/ipv6:amount" value="0"/> <stat name="stats.collection:duration" unit="seconds" value="0.000125647"/> <stat name="stats.processing:duration" unit="seconds" value="0"/> </query> </iq> ```
