Comment:

 Hello Michal-san,

 Replying to [comment:3 vorner]:
 > I had a look (I'm not sure if I should have, if the statistics team
 wanted to review it themselfs). The design makes sense by itself, just two
 notes:

 Thank you very much for reviewing and good feedbacks. I think this
 designing task should be reviewed by non-JPRS members. Since the basis of
 the design have been already discussed in the last F2f meeting, I think
 the internal review by JPRS-only members is no longer important much.

 >  - Would it be possible to specify the configuration by the config
 manager instead of the command line options? After all, this way boss
 needs to know the command line options and it is hard to have full runtime
 configuration.

 Yes, I think it can also accept the configuration from the config manager.
 But the listening address and port number are specified in the command-
 line option. it is like same one in "Cmdctl" or in "Auth". However I think
 other configurations can be specified by the config manager. I have
 updated the wikipage a little according to the thoughts. Please see
 [[StatsModule#HTTPXMLinterface]] again.

 >  - Is it needed for the daemon to be running all the time? As we talked
 on the F2F, there's another possibility ‒ havig a cgi script that would
 start, download the data from stats module, produce the output and
 terminate (therefore not running and taking memory) and we could have any
 web server to listen. If it was considered and decided it is not the way
 to go, then OK.

 Yes, it can be running all the time. In this design, it has the web-server
 implementation but doesn't have CGI scripts.  However another possibility,
 which is having CGI scripts and is depending on a third-party web server
 like "Apache", is also reasonable for me. If other modules also need a
 third-party web server in the future, I think the design of "Stats" module
 may be changed.
