Description Martin Kudlej 2016-02-18 13:01:34 UTC 
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?
Comment 7 Nishanth Thomas 2016-06-20 13:35:19 UTC 
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

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.
