[FSunstone] VM speed graphs always incrementing

[danielbolsson]

Description

1. Graphs showing speed are always incrementing

• Disk read and write IOPS
• Network download and upload speed

2. Wrong heading for "Disk write IOPS" graph. It is now: "Disk write bytes"

To Reproduce
Deploy VM and check graphs

Expected behavior
Graphs should show correct values (up and down slopes).

Details

• Affected Component: FireEdge Sunstone
• Hypervisor: KVM
• Version: 6.6.3 enterprise

After a quick analysis it seems like this might be core related and not an issue directly in Fireedge. The values sent to Fireedge from the core seem to be cumulative across timestamps, thus producing these kinds of graphs.

Legacy Sunstone shows the same graphs correctly. I would guess that it receives values from the same source?

Ah you were absolutely correct @danielbolsson ! After a quick comparison between the two charts in RSunstone and Fireedge it quickly became evident that something was missing. So, the data is indeed being received from the same source, but in RSunstone a derivative function was being applied under the hood to the cumulative data, this was missing in Fireedge. I have corrected the problem and added the same function in Fireedge now! (And fixed the header name)
