anem0neyou have right, all tests are passing07:47
anem0neI've spawned fresh machine, and check, and everything is ok07:47

vtechHello guys, vincentfrancoise, I just noticed there is a bug in the strategy we added recently - https://github.com/openstack/watcher/blob/master/watcher/decision_engine/strategy/strategies/vm_workload_consolidation.py#L98 should be 'unicode' instead of 'str'. Shall I open a new bug report or is there easier way ho to change this one line? sorry for that, don't know how could we missed that.11:12
*** thorst has joined #openstack-watcher11:41
vincentfrancoiseHi vtech11:53
vincentfrancoiseYeah open up a bug ticket and give me the link so I can mark it as "triaged"11:54
vincentfrancoisethen you can assign it to you11:54
vtechvincentfrancoise, https://bugs.launchpad.net/watcher/+bug/156576412:07
openstackLaunchpad bug 1565764 in watcher "Missing support for resource states in unicode format in vm workload consolidation strategy" [Undecided,New]12:07
vtechvincentfrancoise, thank you12:07
vincentfrancoisevtech: you can use six to deal with it so it stays python2/3 comptible BTW12:09
vincentfrancoisevtech: e.g. https://github.com/openstack/watcher/blob/master/watcher/common/utils.py#L5212:10
vtechvincentfrancoise, right. thanks12:14

jed56vtech do you think that you will finish fix the bug before tomorrow ? ( we are releasing mitika rc final)12:26
vtechyes, for sure it's just a matter of adding 'or type(state) == unicode' to the line12:27
jed56great!12:28

vtechvincentfrancoise, I will just use "from six import string_types"12:56
vtechimported within the second import block12:57
vtechand isinstance(state, string_types)12:57
vincentfrancoisevtech: yeah lgtm12:58
vincentfrancoiseFYI, import the module not the function12:58
vincentfrancoiseso isinstance(state, six.string_types) ;)12:58

*** alexchadin has joined #openstack-watcher14:03
alexchadinhello to everyone14:03
alexchadini'm looking for the bug: https://bugs.launchpad.net/watcher/+bug/151017914:03
openstackLaunchpad bug 1510179 in watcher "Can not create an audit template with same name after deleting it previously." [Medium,Confirmed] - Assigned to Taylor Peoples (tpeoples)14:03
vincentfrancoiseHi alexchadin14:04
alexchadindo we really need UNIQUE CONSTRAINT on name column?14:04
vincentfrancoisenot really, hence the bug14:05
alexchadini can handle it14:05
vincentfrancoiseI guess you can assign it to youself14:06
alexchadinok14:06
vincentfrancoisetpeoplesvacation is I believe on vacation so I don't think he would mind14:06
wootehfootHello! Any of you that know a tool that can evaluate VM deployments? As in VMs placed on machines which have their own network topology (IaaS).14:10
jed56wootehfoot : what do you mean ?14:13
jed56you wants a simulator ?14:13
jed56*you want14:14
wootehfootjed56, yeah, a simulator which can handle this case: 1. VMs are placed on machines. 2. VMs begin communicating with eachother. 3. Evaluate bandwidth consumption and machine resource consumption.14:15
wootehfootor another way of evaluating this case, if you have any suggestion14:15
jed56you can try http://www.cloudbus.org/cloudsim/14:15
jed56but the network is not very modelized14:15
jed56you can also try http://beyondtheclouds.github.io/VMPlaceS/14:16
jed56the TCP network is very well design14:17
wootehfootVMPlaceS builds on Simgrid, and Simgrid doesn't permit VMs to have a network topology, but Hosts are allowed however14:17
wootehfootdo you know how to work around that?14:17
wootehfootRegarding CloudSim: Only CloudMIG Xpress supports IaaS, but it's old and doesn't handle my particular case.14:19
wootehfootI'm trying to bend Simgrid and VMPlaceS to my will at the moment, if only it handled VMs with a network topology14:20
wootehfootjed56, what simulators do you use to test Watcher? Or do you test everything online?14:22
jed56we are using Simgrid and CloudSim14:22
jed56but we need to rewrite some parts14:23
jed56in which case do you need to model the network topology of the VM14:23
wootehfootjed56, hmm.. if you had a case where: Incoming traffic is handled by a network of VMs (the vms communicate) which are on machines. And you want to: 1. Analyze bandwidth of links and vswitches. 2. Analyze resources of machines. How would you do it?14:25
wootehfootjed56, i know their network topology, it's an Artificial Neural Network Topology14:25
wootehfootjed56, you can assume i have a full description of the VM communication14:26
wootehfootactually, not "how do you do it", but "which tools do you use?"14:27
jed56sorry coffee break14:39
wootehfootjed56, no problem, found this https://gforge.inria.fr/scm/?group_id=5253 in the mean time, will try it out14:41
jed56yes I know14:43
jed56IMHO, you need to extend VMplaces or SCHIaaS14:44
jed56to you particular use case as we did14:44
