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

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

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
