query command not returning "streams" element

[bhlangonijr]

Hello,

I developed a java client for rtpengine using the ng protocol. Everything went fine until I tried to retrieve channel stats by issuing a 'query' command and passing the call-id of the current streaming as the only parameter. I only got the 'result=ok' and so there was missing the 'streams' element with all channels stats as described in the documentation: https://github.com/sipwise/rtpengine#query-message

Any thoughts? Below the relevant log parts in linux syslog:

Thanks!

Hi,

The stats output (both for "delete" and "query") is not implemented at this time. The layout of the response (as seen in the docs) will have to be redesigned to accommodate the new internal stream handling and I haven't gotten around to it. Should be fixed in the coming weeks.

[bhlangonijr]

Thanks for the quick reply.
Is there any other way to get this info (channel stats)? I would hate to fallback to the old rtpproxy protocol. By the way, does the XMLRPC "call killer" callback method work if you use ng protocol for setting up the relayed call?

Thanks again.

[rfuchs]

Right now, no there isn't, all the relevant code is just commented out and waiting to be re-implemented. Do you need this urgently?

[bhlangonijr]

Yes, I was betting on that for a production case... :)
Are you available for chatting? So I can explain you the details. In case you are available please drop me an email at bhlangonijr at gmail.com with your contact.
