Data is also missing from: v3_2_statistics_vms_disks_resources_usage_samples, v3_1_vm_disk_samples_history_view v3_0_vm_disk_samples_history_view Yes, added regression in keyword DWH gather data correctly where engine has NULL in Read/Write, Engine View is dwh_vm_disks_history_view Table disk_image_dynamic Adding storage keyword, looks like we are missing some statistics report. Reproduced on 3.2/SF5 (In reply to comment #10) > Reproduced on 3.2/SF5 David, why are you testing this? The bug is in "ASSIGNED" status - it was never fixed. Ok, As a response to Vered This bug is marked as REGRESSION - when was was the last time that it worked? (3.1? 3.0?) According to Yaniv Dary the actual select query creating dwh_vm_disks_history_view returns no records, which means this is not a reports/dwh issue and can be fixed on the engine alone. I.e., no need for winXP/dwh/reports installations. We expect to see data on disks of currently running VMs in the system. Same as Vered, Issue is at the engine DB (In reply to comment #15) > Same as Vered, Issue is at the engine DB This is not the question. I ask again: In what version was this last confirmed to work? The Disk IO stats were working at 3.0/ic138.1 (Bug 733290) Same issue as the this BZ was Also reported In 891322 - 3.1/si24 disk_image_dynamic table does not gather statistics, hence related dwh views are empty. 3.1 introduced DiskImage entity to the system, separating (engine) image group and image id (or image and volume in vdsm, respectively). The data received from vdsm is (correctly so) for image group, while the data in the table is updated by image id (volume). Hence no data is actually updated. Hi Vered, Is this BZ fixed for 3.2/sf13 ? (In reply to comment #21) > Hi Vered, > Is this BZ fixed for 3.2/sf13 ? Yep, see external tracker for more info. Fixed, 3.2/sf13 History DB has data in all 3 views samples/hours/daily - VM_DISK_Read/Write Fixed, 3.2/sf13 3.2 has been released 3.2 has been released 3.2 has been released |
Created attachment 673922 [details] rhevm-logs Description of problem: No Statisitics for Disk Read/Write in Views (v3_2 & v3_1) vm_disk_samples_history_view (if there is no data in samples it affects both hours & days) This applies for both DC's versions 3.1 & 3.2 on rhevm 3.2 Version-Release number of selected component (if applicable): 3.2/SF3 How reproducible: always Steps to Reproduce: 1.Installrhevm+dwh+reports on RHEL64 Hosts 2.Create DC 3.1 or 3.2 with 1 host 3.Create 1VM Winxp from template or new with IOLoadGenerator 4.run IOLoadGenerator.exe -f iozone/iozone.exe Actual results: Data is not saved in the correct tables/views for vm_disk_samples_history Expected results: Should save & display the Read/Write data Additional info:
