wido	Regarding the I/O throttling with libvirt: http://tracker.ceph.com/issues/2700	08:30

loicd	http://pad.ceph.com/p/Ceph_management_API	08:30

rturk	thx, loic	08:30

loicd	:-)	08:30

sagewk	if anybody wants to participate in teh discussion/hangout, raise your hand :)	08:34

loicd	could you please link to the wip git branch ?	08:35

sagewk	hmm let me find it	08:35

sagewk	i think the wip might be in dan's git tree, not in the main ceph.git	08:36

loicd	sagewk: ok :-)	08:36

loicd	Christopher Liljenstolpe are you around ?	08:36

fghaas	I'll just say here that rewriting the CLI in Python is ultra-w00t. specifically when you actually use things like OptionParser and docstrings and whatnot.	08:36

loicd	fghaas: +1	08:37

joshd	fghaas: yeah, docs and option parsing become much nicer and bash-completable even	08:37

fghaas	joshd: yes, re bash completion, steal as much as you can from hg and the openstack CLIs	08:37

saras	python is good to hear	08:38

*** jtaguinerd has joined #ceph-summit1	08:38

sagewk	the bash completion will be automagic too, based on the set of supported commands the monitor provides	08:38

sagewk	eventually with things like pool name completions and so forth	08:39

nwat	Does management API also include stuff like per-OSD HTTP end points for grabbing things like perf counters, stats, logs, etc…?	08:40

sagewk	nwat: right now that comes out of the 'admin socket' (/var/run/ceph/ceph-osd.0.asok unix domain socket)	08:41

sagewk	i think the new mgmt gateways will eventually be able to query the same command set, but via the network...	08:41

nwat	sagewk: right. i meant, will admin socket data eventually be exposed through http	08:41

nwat	sagewk: i see cool	08:41

sagewk	we're not too keen on embedding an httpd in each daemon, though	08:42

paravoid	we've experimented with a ganglia plugin that fetches and graphs those	08:46

paravoid	graphite is better suited to the cause though	08:46

*** ccourtaut_ has joined #ceph-summit1	08:48

loicd	I assume having a REST API will help with integration. Has there been requests from OpenStack, Cloudstack, people writing salt / ceph / puppet modules ? How do they feel about this change ?	08:49
