boris-42rook: it is because you have few default groups13:29
rookboris-42: my code cleans up sec groups before each rally run13:29
rookto augment this issue i create more tenants and users.13:29
boris-42rook: https://github.com/openstack/rally/blob/master/rally/benchmark/scenarios/nova/utils.py#L116-L147 take a look13:30
boris-42rook: rally doesn't manage default groups at all13:30
boris-42rook: btw we fixed that issue (and rally cleans default groups now)13:30
rook:)13:30
rookgood so i don't have to anymore13:30
rookboris-42: something is creating def sec-groups when rally runs13:31
rookmaybe it is neutron13:31
boris-42rook: nova or nuetron13:32
boris-42rook: depending on what you are using13:32
rookthere is a known race condition in neutron which is fixed in kilo13:32
boris-42rook: yep I know13:32
rookand rally exposes this pretty bad13:32
boris-42rook: I detected it13:32
boris-42rook: and I was helping fixing it=)13:32

boris-42rook: hm14:04
rookboris-42: seems to be a list of names :)14:04
boris-42rook: it should be list of names as far as I know14:04
rookhaha14:04
boris-42rook: yep14:04
rooktrial and error14:04
rookit would be very nice to identify the kwargs and what they are expecting14:05
rooknot all of them14:05
boris-42rook: it's impossible14:05
rookbut what each function might use.14:05
boris-42rook: it depends on python clients commands that we are using14:05
boris-42rook: so you should take a look each time in specific python client14:06
rookhaha i have.14:06
rookit would just be a Nice to have.14:06
*** e0ne_ is now known as e0ne14:06
boris-42rook:  so it will be nice if python clients are better and they will provide such info14:06
rookpreach14:06
boris-42rook: but it is impossible to organize such work in community14:06
boris-42rook: at least I am not able to lead such efforts=)14:07
boris-42I am to aggressive =)14:07
boris-42rook: retweet required https://twitter.com/PavlovicBoris/status/598838569793429505 =)14:07

boris-42vaidy: pong15:18
vaidyboris-42, first of nice to hear on the new release15:18
boris-42vaidy: thanks15:19
vaidyboris-42, had a question on deployment create, is it mandatory that the json should have the admin user as mandatory entry to create a deployment?15:20
vaidyboris-42, i see even the code is been designed the same way15:20
boris-42vaidy: for now yea15:20
boris-42vaidy: I am working on dropping this15:20
Vishal_amaretskiy: I feel there should be benchmarking done when overlapping Ip's are there in neutron...since i had seen different performance of neutron in case of overlapping and non-overlapping15:20
*** PerfBeing has quit IRC15:20
vaidyboris-42, ok15:21
boris-42vaidy: as first part we drop the requiremtns to create new users15:22
boris-42vaidy: so now you can use existing users in system to do the load15:22
boris-42vaidy: next step is to finish plugin base, move validation to it, and unify validation mechansim for context/scenarios/runners/sla15:22
openstackgerritMerged openstack/rally: Add E126 pep8 rule  https://review.openstack.org/18302915:23
vaidyboris-42, ok15:24
*** baker has quit IRC15:24
vaidyboris-42, but makes i can understand the current architecture of the code15:24
boris-42vaidy: so current architecture of the code is in the middle of moving from generating load just with admin user -> to the abbility to generate load with what you have15:25
boris-42admin, admin + temp users create by rally, admin + existing users, existings users, or even just without openstack at all15:26
boris-42vaidy: ^15:26
boris-42vaidy: as you can see on scenarios there is validator that ask do you need openstack and the rest stuff15:26
vaidyboris-42, yeah15:26

*** baker has joined #openstack-rally15:37
boris-42vaidy: becasue before it was just impossible15:37
vaidyboris-42, yes we already are trying it15:37
vaidyboris-42, but we are restricted with non admin access though15:37
vaidyboris-42, this should solve that problem15:37
boris-42vaidy: so this will be implemented during liberty15:40
vaidyboris-42, hmmm15:40
*** pradeep has joined #openstack-rally15:41
vaidyboris-42, ok15:41
Vishal_amaretskiy: The problem is the tenant and user for any particular iteration are chosen randomly...for the same tenant I have to generate a unique cidr so that within the tenant there is no overlapping...but for different tenant I want to use the same cidr ranges which were generated earlier so that they can overlap15:42

boris-42rook: yep18:46
boris-42rook: you should create user18:47
boris-42rook: boot single VM18:47
boris-42rook: remove it18:47
boris-42rook: after that you can benchmark18:47
rookhm, the default sec-group exists without that.18:47
rook| e586a999-3c59-42e3-b457-3b88a59a2226 | default | default     |18:47
rookis there something else that does?18:47
*** botang_ has joined #openstack-rally18:48
boris-42rook: after creating user18:49
boris-42rook: you should create VM to create defaut sec group18:49
boris-42rook: that is actually the race18:49
boris-42rook: if you create them sinulatnously18:49
boris-42rook: it may create 2 default18:49

georgem1I ran the task "NovaServers.boot_server" with "times": 10 and "concurrency": 10. After it completed successfully, I don't see any new instances19:20
*** PerfBeing has joined #openstack-rally19:21
georgem1can somebody please explain me how it works…this is the task http://pastebin.com/m6E83BxQ19:22
georgem1I assumed it would create 3 temporary tenants with 2 users each and use them to start these VMs (10x10 ?), which should not be deleted at the end..also, what should happen with the temporary tenants and users?19:24

boris-42georgem1: hm?19:44
boris-42georgem1: nope19:44
boris-4210 times is total amount19:44
boris-42so it will create 10 workers each worker will create 1 vm19:44
boris-42after that generic cleanup mechanism will delete everything19:44
georgem1ok, where are the vms?19:44
boris-42they are cleaned up19:44
boris-42by Rally19:45
boris-42Rally don't leave any resources19:45
boris-42(or at least it shouldn't)19:45
georgem1even if I only ran boot19:45
boris-42cleanup is separated steps19:45
boris-42step*19:45
boris-42during the load it won't clean anything19:45
boris-42after load will be finished it will clean all VMs and all tenants/users19:46
georgem1so, what's the difference between the tasks "NovaServers.boot_server" and "NovaServers.boot_and_delete_server" ?19:46
boris-42load is different19:47
boris-42you are repeating N times creae or create-and-delete19:47
boris-42as a result in boot_server there will be more and more active VMs19:47
boris-42and in case of boot_and_delete the amount of active/in status of creation/deleteion will be the same as concurrency all the time19:48
boris-42georgem1: ^19:48
georgem1I see, so create-and-delete deletes them right away, as opposed to just create that deletes at the end19:48
*** cdent has joined #openstack-rally19:49
boris-42georgem1: yep after all iterations are run19:49
boris-42georgem1: so if you would like to get at the end 100 active VMs by creating 10 simultaneosuly19:49
boris-42times: 100, concurrency: 1019:49
*** abehl has joined #openstack-rally19:49
georgem1ok, actually, I want to test with 500, so it should be times: 500, concurrency 50 ?19:50
georgem1it will run 10 batches of 50 ?19:51
boris-42georgem1: there are not actually batches19:51
boris-42georgem1: there will be 50 workers that are simultaneously executing this stuff19:51
boris-42georgem1: scenario19:51
*** openstackgerrit has quit IRC19:52
boris-42georgem1: unit it won't be run 500 times19:52
boris-42georgem1: depending on duration19:52
*** neeti has joined #openstack-rally19:52
*** openstackgerrit has joined #openstack-rally19:52
*** neeti has quit IRC19:52
georgem1I see, but it's fair to say there will be 500 nova boot API calls in the end19:52
boris-42georgem1: it may happen that one worker will run 51 and another 4919:52
boris-42georgem1: yep19:52
georgem1cool, thanks for the info19:53
*** cdent has quit IRC19:57
georgem1boris-42: another question please..how does rally verify the instance started is really alive?20:01
boris-42georgem1: if it is boot_server than it will be just status in nova db20:01
boris-42georgem1: so if nova says that it works then it's ok20:02
georgem1boris-42: is there a task that also pings the instance's IP?20:02

boris-42georgem1: so there is VMTask.boot_and_runcommand20:13
boris-42georgem1: it boot vm attach floating ip wait for ping wait for ssh and executes command inside vm collects output and remove VM20:13
georgem1boris-42:this sounds more accurate, I just wished it wouldn't use a floating IP as it's not going too well for large scale testing; it would probably run into arp issues, floating ip alloc/dealloc issues, etc; it would be nice if the first VM would be used as a jumpserver, but too complicated to implement..20:17
*** abehl has joined #openstack-rally20:17
*** igormarnat is now known as imarnat20:18
boris-42georgem1: it can work with fixed ip20:21
boris-42georgem1: you need just to specify20:21
boris-42georgem1: to not use floatip20:21
boris-42georgem1: but as you understand you should see the fixed network from where do you run rally20:21
georgem1boris-42: how do I specify the user to run as and the network to attach to? I can run rally from an instance owned by a "rally" user in the "rally" tenant if need be20:24

boris-42georgem1: or have rally on controllers20:37
boris-42georgem1: it really depends on your network configuration20:37
