chenketoday i want to talk about instane.name and node.name08:13
*** panda|ruck has quit IRC08:14
licanweiDantalion: about backwards compatibility,08:14
licanweihttps://review.opendev.org/#/c/656622/08:16
licanweithis merged patch has backwards compatibility problem08:17
*** derekh has joined #openstack-meeting-alt08:18
DantalionOther than with strategy or datasource plugins?08:18
DantalionI think since the interface changed compatibility problems are impossible to prevent but happy to hear ideas08:19
licanweiDantalion: we changed the audit parameter,  about basic strategy , change node to compute_node , for example08:20
licanweiIn Stein, some tempest tests failed, https://review.opendev.org/#/c/662045/08:21
DantalionAh yes that is true we could do that it can be both node and compute_node and stop support node in next release. I think compute_node is more clear but should support both for at least a while08:21
licanweiDantalion: yeh, I agree with you08:22
DantalionDo we want spec for this or should I just do it?08:22
licanweiDantalion: I don't think we need a spec, it's clear :)08:22

licanweilast one:https://review.opendev.org/#/c/660011/ Add resource_name in action input parameter field needs new patch08:28
*** panda has joined #openstack-meeting-alt08:28
DantalionI will try to review next week08:29
Dantalionafter we have decided on humand_id / name08:29
licanweiWe need to define how to use humand_id /instance name/host name ...08:30
licanwei# topic Discussion08:30
chenkeI think instance name is clear than human_id08:31
licanweiNow let's discuss again08:31
licanweiIn Watcher data model, compute node and instance all have human_id field08:32
licanweiexample:08:32
licanwei<ComputeNode status="enabled" disk_capacity="74" uuid="ubuntu-bionic-limestone-regionone-0007063015" hostname="ubuntu-bionic-limestone-regionone-0007063015" vcpus="8" human_id="" state="up" memory="7975" disk="73" disabled_reason="None" id="ae0b72a3-58b3-41d9-bd0d-5b765bfeb796">08:32
licanwei<Instance disk_capacity="1" locked="False" uuid="3a2f9d3a-ccd0-4545-9556-291b7740df2b" watcher_exclude="False" vcpus="1" disk="1" state="active" memory="64" project_id="e24e6c9bbc6945c58da3bcc9c87d4929" human_id="tempest-testexecutestrategies-server-1452042406" metadata="{}"/>08:32
licanweiNow computenode' s human_id is null08:33
licanweiand compute node also has a hostname field08:33
licanweiI think we should define how to use these fields08:34
chenkeI think uuid and hostname is enough.08:35
licanweiremove human_id ,use hostname and instance name08:35
licanweior remove hostname and instance name, use human_id08:35
licanwei?08:35
licanweiNow human_id is unused08:36
Dantalioninstance human_id is how we identify virtual machines for Grafana08:37
chenkeWhy not using uuid?08:38
licanweiDantalion: Why don't you use vm uuid?08:38
*** radeks has joined #openstack-meeting-alt08:38
DantalionBecause storing hostname as identifier allows to query dns server to get ip without having to use openstack clients for example08:39
DantalionWhich identifier to use for storing is not something I can control either is managed by other team08:39
Dantalionbut keep in mind what identifier to use is configurable and will differ in every deployment this is simply how CERN has done it.08:40
licanweiDantalion: Is VM name OK?08:41
chenkelet me see novaclient's code08:43
chenkehttps://github.com/openstack/python-novaclient/blob/2595bac2294ce05e389eaab6636977963d5fc66c/novaclient/base.py#L15208:44
licanweiDantalion: Because instance human_id comes from nova client, maybe we plan to get data directely from nova API08:44
Dantalionso human_id = instance_data['human_id'] ?08:46
*** tetsuro has quit IRC08:46
licanweijust like that placement helper08:46
DantalionOr do you mean if data from model is missing just use uuid to get object from nova API?08:47
chenkehuman_id = instance_data['name']08:47
licanweiDantalion: No, I mean maybe we can get rid of novaclient, get data directely from nova API08:48
DantalionWhat is the benefit of using nova API directly?08:50
*** panda is now known as panda|ruck08:52
chenkeNow, when watcher create datamodel , instance's human_id actually is instance.name, but when updating datamodel, instance'human_id uses ['display_name']08:52
licanweiDantalion: If we use nova API directly, we will don't need Matt to change novaclient for optimization08:53
chenkeWe need to confirm that their values are currently the same field08:53
chenkeI think we need novaclient.08:54
DantalionAh I see, can someone show example difference between instance.name and display_name as I have no access to an openstack08:54
chenkeLet me have a try.08:54
licanweiDantalion: need to confirm the difference~08:56
licanweiI'll confirm after the meeting08:57
DantalionOkaj yes I agree that the update should use same value as used when creating the data model.08:57
chenkeokaj08:58
licanweiDantalion: yes08:58
*** rcernin has joined #openstack-meeting-alt08:58
chenkei will confirm this after our meeting08:58
DantalionWe need to be careful to keep value that looks like hostname from compute_node in instance data model in the example: tempest-testexecutestrategies-server-145204240608:58
Dantalionthis will be used at CERN to identify virtual machines in Grafana databases08:59
licanweiOk08:59
DantalionBut I do not mind if the attribute is renamed08:59
licanweithank you all08:59
licanweiI'll end the meeting08:59
DantalionYes thank you08:59
