Description of problem: I see in Graphite UI for example for one node for memory consumption different graph than in Kitoon. For example in Graphite there are no peaks there because there are no changes in memory usage. In Kitton I see peaks(list of hosts) so I expect that there is no real data but random one. Version-Release number of selected component (if applicable): rhscon-core-0.0.8-4.el7.x86_64 rhscon-ceph-0.0.6-4.el7.x86_64 rhscon-ui-0.0.14-1.el7.noarch How reproducible: 100% Actual results: There are differences between Graphite graphs and graphs in Kitoon for same data type for one node. Expected results: Data in graphs will be in Graphite and Kitoon similar.

Can you please verify this issue is reproducible?
As discussed in the bug scrub meeting, the issue with peaks in utilization graphs(caused due to null values being plotted) is fixed. Also you have to take the polling intervals into account when comparing the values in usm vs graphite
This is a comment with QE verification details. Version-Release =============== On RHSC 2.0 server machine: ceph-installer-1.0.14-1.el7scon.noarch ceph-ansible-1.0.5-32.el7scon.noarch rhscon-ui-0.0.52-1.el7scon.noarch rhscon-core-selinux-0.0.41-1.el7scon.noarch rhscon-ceph-0.0.40-1.el7scon.x86_64 rhscon-core-0.0.41-1.el7scon.x86_64 On Ceph 2.0 machines: ceph-common-10.2.2-36.el7cp.x86_64 ceph-selinux-10.2.2-36.el7cp.x86_64 rhscon-core-selinux-0.0.41-1.el7scon.noarch rhscon-agent-0.0.18-1.el7scon.noarch Verification ============ I no longer see such big discrepancies between graphite data and charts shown in RHSC 2.0 console. When I check sparkline chart of some value on given machine and compare it with chart as plotted by graphite-web interface, I see that both plots resembles each other. See attached screenshots.
