sparkline CPU

Description of problem:
on sparkline for CPU are drawn some changes, but the tooltip says 0%

Version-Release number of selected component (if applicable):
ovirt-engine-dashboard-1.0.3-1.el7ev.x86_64

How reproducible: always


Steps to Reproduce:
1. install new engine or stop all VM for some time (for few hours)
2. create new VM with no OS, assign a disk and run it
3. wait 15-20 minutes and reload the Dashboard

Actual results: sparkline changes and tooltip shows 0%


Expected results: tooltip shows 0.x% or <1%


Additional info:
I assume that the last day values are counted as avarage for sample values for every X minutes and so that is not equal to 1, but its confusing to see always 0%, even if the sparkline changes

for cpu usage lower than 1 still shows 0.0%

Target release should be placed once a package build is known to fix a issue. Since this bug is not modified, the target version has been reset. Please use target milestone to plan a fix for a oVirt release.

Greg, can you take a look?
Comment 6 Greg Sheremeta 2016-10-28 05:33:30 UTC 
Yes sir
Comment 7 Scott Dickerson 2016-10-31 21:23:17 UTC 
The second patch (65925) tests if the percent to be rendered will be greater then 0% but less then 0.1%.  If it is in this range, "<0.1%" will be shown.  If the percent is 0, "0.0%" will be shown.  

This change allows easy differentiation between 0 and a value smaller then the smallest formatted value of "0.1".
Comment 9 Lucie Leistnerova 2016-12-01 13:01:04 UTC 
values in cpu tooltips are OK

verified in ovirt-engine-dashboard-1.1.0-0.4.20161128git5ed6f96.el7.centos.noarch
