flwangkgriffs: ping21:33
flwangsome questions about the zaqar billing21:33
kgriffsamitgandhinz: around?21:34
amitgandhinzyo21:34
kgriffsflwang: amitgandhinz knows more about billing than I do, so I'll defer to him21:35
amitgandhinzlol you are so kind kgriffs21:35
kgriffs:D21:36
amitgandhinzflwang: whats up21:36
flwangwe(catalyst IT in NZ) are going to deploy zaqar in our prod, then we need to know how to bill it, seems AWS' SQS and Rackspace are billing mq service based on api request, right?21:37
flwanghowever, there is no similar service like AWS CloudTrail in OpenStack21:37
flwangso how Rackspace to do that?21:37
flwangi assume there are some private code/service, is it?21:38
amitgandhinzflwang: yeh we have internal services for billing21:38
amitgandhinzbasically we bill per request21:38
flwangso how to count the request? did you hack the zaqar code to get the number?21:39
amitgandhinzso we have middleware running on top of zaqar that surfaces each request and puts it on a zaqar queue21:39
amitgandhinz(yes we use zaqar to bill for zaqar = inception =p)21:39
flwangor you get the api calls at the proxy layer?21:39
amitgandhinzmiddleware - using EOM21:39
amitgandhinzlet me see if that code is public - one sec...21:39
flwangamitgandhinz: cool, thanks, new zealander :)21:40
amitgandhinzflwang: https://github.com/racker/eom21:42
amitgandhinzflwang: yup, im from wgtn21:42
flwangamitgandhinz: haha, yep, iirc, you're from lower hutt :D21:42
amitgandhinzanyway, so we wrap zaqar with eom and have it surface request counts to a redis node21:42
amitgandhinzwe then have our own workers that aggregate these requests by project_id and post them to a zaqar queue21:43
amitgandhinzanother worker then picks them up from the queue and post them to our own metering system (cloud feeds)21:43
amitgandhinzfrom there internal billing takes over21:43
flwangah, so you're even using zaqar as a queue for your internal billing? it's awesome21:46
flwangso EOM can save the request statistics into a database(redis) node, and then we just need some code to grab the data from db for billing, is it?21:47
amitgandhinzcorrect.  But you may want to do aggregation etc depending on how you bill21:48
amitgandhinzwe take the raw usage, save it, aggregate it, then post it to billing21:48
flwangcool, thank you so much for that21:49
amitgandhinzand use zaqar for stuff like claim ttl etc to ensure we dont lose messages etc21:49
amitgandhinzif a worker crashes21:49

flwangamitgandhinz: btw, is there any known issue about deployment we should know?22:00
amitgandhinzno known issues (but to be honest our instance of zaqar running in prod is pretty old).  we need to update to the latest code which we plan to do soon22:01
