Disk Statistics API in Ovirt

Windows VMs won't boot in debug mode
by Andrew X 17 Jul '18

17 Jul '18

Hi Everyone, I've been having problems getting Windows 10 VMs to boot in debug mode after turning on debugging over network (steps below). Also, device manager in Windows is not showing the processors' node which might be related (same reason why Windows is refusing to boot in debug mode?). I don't have any of these problems when I use generic KVM or Proxmox KVM. To turn on debugging in Windows, I do the follwoing from an admin terminal window: bcdedit /debug on bcdedit /dbgsettings net hostip:a.b.c.d port:p key:1.2.3.4 Any help will be appreciated, Thanks, Andrew

Hi Team, We are using the following API to collect the disk statistics, https://X.X.X.2/ovirt-engine/api/ *disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics* <https://X.X.X.2/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda…> I found one issue in the disk statistics. In case If the Virtual Machine has this disk (*2331bad7-71ec-4fad-95bb-2b3449f3dbda*) attached to it and I perform some read / write operation in the VM and it increases the corresponding disk level Read data rate / Write data rate / disk.read.latency / disk.write.latency. *Example*, I received the following values for this disk, But the problem is even when I bring down the VM still the last known value is received continuously. *Is it a known issue Or any workaround is available? * *Expected : All values should go to Zero* *Actual : All values retains the last known values when the VM was in UP state. * { "statistic": [ { "kind": "gauge", "type": "decimal", "unit": "bytes_per_second", "values": { "value": [ { "datum": 2184 } ] }, "disk": { "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda", "id": "2331bad7-71ec-4fad-95bb-2b3449f3dbda" }, "name": "data.current.read", "description": "Read data rate", "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics/33b9212b-f9cb-3fd0-b364-248fb61e1272", "id": "33b9212b-f9cb-3fd0-b364-248fb61e1272" }, { "kind": "gauge", "type": "decimal", "unit": "bytes_per_second", "values": { "value": [ { "datum": 41202005 } ] }, "disk": { "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda", "id": "2331bad7-71ec-4fad-95bb-2b3449f3dbda" }, "name": "data.current.write", "description": "Write data rate", "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics/2f23addd-4ebd-3d82-a449-c28778bc33eb", "id": "2f23addd-4ebd-3d82-a449-c28778bc33eb" }, { "kind": "gauge", "type": "decimal", "unit": "seconds", "values": { "value": [ { "datum": 0.12 } ] }, "disk": { "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda", "id": "2331bad7-71ec-4fad-95bb-2b3449f3dbda" }, "name": "disk.read.latency", "description": "Read latency", "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics/3a7b3f72-d035-3bb9-b196-e86a4eb34993", "id": "3a7b3f72-d035-3bb9-b196-e86a4eb34993" }, { "kind": "gauge", "type": "decimal", "unit": "seconds", "values": { "value": [ { "datum": 1.4 } ] }, "disk": { "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda", "id": "2331bad7-71ec-4fad-95bb-2b3449f3dbda" }, "name": "disk.write.latency", "description": "Write latency", "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics/b1e75c7b-cea4-37d2-8459-f7d68efc69a3", "id": "b1e75c7b-cea4-37d2-8459-f7d68efc69a3" }, { "kind": "gauge", "type": "decimal", "unit": "seconds", "values": { "value": [ { "datum": 0 } ] }, "disk": { "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda", "id": "2331bad7-71ec-4fad-95bb-2b3449f3dbda" }, "name": "disk.flush.latency", "description": "Flush latency", "href": "/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics/9c17ad7b-9ef1-3e8d-ad0a-ff8bee3925f0", "id": "9c17ad7b-9ef1-3e8d-ad0a-ff8bee3925f0" } ] } Thanks, Hari -- DISCLAIMER - *MSysTechnologies LLC* This email message, contents and its attachments may contain confidential, proprietary or legally privileged information and is intended solely for the use of the individual or entity to whom it is actually intended.

Hello, This is more out of curiosity, I was wondering during a migration or import/export does all the storage traffic goes through the SPM server? Thanks John

Jump from a disk to its storage domain from VM disk
by Gianluca Cecchi 16 Jul '18

16 Jul '18

Hello, currently on 4.2.3 I can - Select Storage --> Disks - Select disk link in the line (in the "Alias" column) - In the new disk page select "Storage" tab and I can see the related Domain Name and its information (eg free space if I want to extend the disk) --> it would be nice to have a "link" on domain name so that you can directly jump to Storage --> Domains --> Domain Name It would be nice to have similar behavior also directly starting from Compute --> Virtual Machines Select VM --> Disks Select disk Here I can select "edit" and then in the edit window I can see information about storage domain between the other fields. It would be nice to have a pointer to directly go to the storage domain containing that disk. Gianluca
