Description of problem (please be detailed as possible and provide log snippests): This BZ is subset of https://bugzilla.redhat.com/show_bug.cgi?id=2026144 for tracking the enhancement on IOPS, Throughput & Latency values to match with ODF Overview page and Overview Block & File page. During backport verification of BZ https://bugzilla.redhat.com/show_bug.cgi?id=2124282 observed Latency difference around ~2ms, after discussion with dev came to know about the comment from Arun https://bugzilla.redhat.com/show_bug.cgi?id=2026144#c20 on why this difference or mismatch. Copying comments from BZ 2026144#c20 ODF Overview page graphs (IOPS, Throughput and Latency) shows the sum of Read+Writes of I/O when compared with the separate Read and Write graphs in StorageSystem's -> Overview Block & File page. So both set of graphs won't have a one to one correlation. For, IOPS ODF Overview page and StorageSystem Overview page has different time intervals. Throughput Underlying queries are different with different collection interval. Latency Again two totally different queries (where one taking an average and the other taking sum). For IOPS we can correct the time interval and make it same and for the other two need to check/investigate a bit further on the queries. Version of all relevant components (if applicable): Does this issue impact your ability to continue to work with the product (please explain in detail what is the user impact)? NA Is there any workaround available to the best of your knowledge? NA Rate from 1 - 5 the complexity of the scenario you performed that caused this bug (1 - very simple, 5 - very complex)? 1 Can this issue reproducible? Yes Can this issue reproduce from the UI? Yes If this is a regression, please provide more details to justify this: Steps to Reproduce: Install odf operator 2. Create storagesystem 3. Navigate to ODF tab under Storage, on Overview page, check the values of IOPS, Throughput, Latency from Performance card and Used Capacity value from System Capacity card on this page. 4. Match these values against the values listed in Utilization card on Block and File tab. Click on ocs-storagecluster-storagesystem hyperlink from Performace card on Overview page to navigate to Block and File tab. Actual results: There is difference in values for IOPS, Throughput and Latency between ODF Overview page and Overview Block & File page Expected results: Values of IOPS, Throughput and Latency between ODF Overview page and Overview Block & File page should match. Additional info: NA
BZ https://bugzilla.redhat.com/show_bug.cgi?id=2026144 has the fix for query and time mismatch. Actual problem is with 4.9 UI. In latest 4.12 there is a Read and Write color coding data in StorageSystem Block and File page but in 4.9 there is no clarity on either its aggregate of both read and write or its just only write/read. Attached screen shot for reference, When we backport any changes in ocs-operator then corresponding UI change/update PR's too should be backported to avoid above mentioned problem.
Based on comment 2, 3 & 4 closing this BZ
