Network Switch wizard graphs - Confusing
Posted: Tue Dec 21, 2010 12:26 am
I am trying to understand how the Network Switch wizard graphs work, some of the results I am getting are inconsistant.
I ran the Network Switch wizard three times. I monitored the same device each time but gave it a different hostname and changed the Label/Scale each time (bps, Kbps, Mbps). The warning and critical values have been left enabled with default values.
Here are the three graphs that are produced (bps, Kbps, Mbps).
Graph Scale vs Overview Scale
For each graph, the data displayed under the graph is not the same scale as the data displayed on the Overview tab.
For example on the Mbps service:
The Overview tab shows the Bandwidth as in: .26Mbps and Out: 1.91Mbps
The graph figures shows the Bandwidth as in: 223.97 mb/s and 1535.31 mb/s
I do understand the graph may be a few minutes outdated but the numbers themselves appear to be on a different scale.
Why is this happening?
A few of my co-workers have commented on how this seems confusing.
bps service is displaying in Mbps
On the bps service Overview tab it shows the Bandwidth as in: .26Mbps and Out: 1.91Mbps
When the Network Switch wizard was run I selected bps as the Label/Scale to be used
For the Kbps and Mbps services the Overview tabs are correctly matching the Label/Scale I chose when I ran the Wizard
Why is this happening?
Critical Threshold/Trigger
On the Kbps service, on the Overview tab the service is in a Critical state
However on the bps service it is not in a critical state
Both services were created identically using the Network switch wizard, the only difference between the two was the Label/Scale that was chosen. The warning and critical values were left enabled and as default.
If Kbps triggered a critical alert then shouldn't the bps service be in a critical state as well?
Unit on X axis
Is it possible to make the X axis of the graph show the unit scale that is being displayed?
For example the bps and Mbps graphs show nothing however the Kbps graphs have a k next to each unit number
Several co-workers have asked me if this is possible to define, their reasoning is that they want to easily know what they are looking at without having to try and work it out.
This is on Nagios XI 2009R1.3G, VMware image running on ESXi.
