Measures reported by RHEVVMNetTest
Red Hat Enterprise Virtualization Manager supports multiple virtual networks and VLANs, allowing an administrator to centrally manage and configure the virtual network. Virtual networks emulate network connectivity within the RHEV server and allow VMs hosted on that server to exchange data. Continuous monitoring of these virtual networks will enable administrators to isolate which virtual networks are healthy and are too busy trafficking data to and from VMs, and which virtual networks are experiencing error conditions. The RHEVVMNetTest does just that.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Data_trans |
Indicates the rate at which data is transmitted over this virtual network of the RHEV hypervisor. |
Mbps |
A high rate of incoming and outgoing data could indicate that the virtual network is very busy or is been overloaded with traffic. |
| Data_rec |
Indicates the rate at which data is received over this virtual network of the RHEV hypervisor. |
Mbps |
| Trans_err |
Indicates the number of errors that occurred while data was transmitted over this virtual network of the RHEV hypervisor. |
Number |
Ideally, the value of both these measures should be 0. Comparing the value of each of these measures across virtual networks will introduce you to the error-prone networks. |
| Rec_err |
Indicates the number of errors that occurred while data was received over this virtual network of the RHEV hypervisor. |
Number |
