konghi, guys, i got question from our customer. They were downloading multiple objects using CLI by specifying '--object-threads', but during download, from iftop only one connection to swift service can be seen, is there something we are missing?02:08

mattoliveraum_kazuhiro, zhongjun: morning02:17
*** klrmn has joined #openstack-swift02:24
mattoliveraukong: not sure, don't know if there is enough info. it should default to 10 threads. How were they downloading the objects. By specifying them in the same command? or downloading a whole containers object at once?02:26
kongmattoliverau: like this: swift download --object-threads=2 container obj1 obj2 obj302:27
kongand thanks for reply btw02:28
mattoliveraualso, how are they using iftop? if no ports displayed wont it only show it as 1 connection as all traffic going to your swift clusters hostname (vip for a load balancer I assume)02:28
mattoliveraukong: ^02:28
mattoliverauSo I assume it'll look like 1 connection.02:29
mattoliverauNoting: I'm not used to using iftop, I just installed it then to look :)02:29
kongmattoliverau: hmm...not famaliar with iftop neither, seems more communication with customer needed02:30
m_kazuhiromattoliverau: zhongjun :morning02:30
kongi asked just in case someone had asked before or someone has some experience02:30
mattoliveraukong: I'm just looking at my machine and all my traffic going over a VPN seems to be mainly going to 1 host, but I'm sure there is more the 1 connection to it.02:30
kongmattoliverau: yeah, i printed the conn var in swiftclient, they are different for different objects obviously02:31
mattoliveraukong: maybe someone else has or was around if they did. But not me.. but if we figure it out with your customer, then next time I will have experience ;P02:31
kongand the connection in swift client is implemented using requests lib02:31
*** itlinux has quit IRC02:32
mattoliveraukong: if I press 'p' for port in iftop, I suddendly see 2 connections to the openstack etherpad server (as a connection example). If I turn off ports ('p' again) I can only see one. So they do collapse and look like a single connections. As I assume it's just using the host (without port) as a filter for display02:36
mattoliverauSo make sure they have ports on (including the source port) if they are using iftop. Otherwise look at something like netstat to see connections.02:37
mattoliverauNow if they do that, and are actually only getting 1 connection, then we'd need to figure out why.02:38

kongmattoliverau: thanks! I will test on my local first before i tell them the truth ;-)02:40

notmynameacoles: yeah, tshirts more than faces, these days16:47
notmynametdasilva: yeah, I saw a comment about the fact that with docker, since it's "just processes", the kernel can do better scheduling. with TinyVMs, the hypervisor ends up being the kernel since the host kernel doesn't have any insight into the VMs16:48
notmynamehowever, I'm not sure if I completely buy that16:49
notmynamethat is, it sounds like a reasonable argument that's likely true, but one that is solved over time with thinking hard and typing16:49

mattoliveraunotmyname: oh yeah, It is a doc prob so was going back and forth on the -1. But if it lands with the setup tmp instructions in a state that doesn't work and doing something to get an xfs tmp is required for all devs, as without it tests won't work. Then it isn't a normal doc bug. (Tho I guess it is pretty obvious what's wrong). At least that was my rationale. Also I have no idea if this sentence makes sense cause19:38
