Introduction:

This section is applicable to the following editions of IT360;

Supported Versions:

Hyper-V Server 2008 R2, Windows Server 2008 R2 Standard, Windows Server 2008 R2 Enterprise, Windows Server 2008 R2 Datacenter.

Monitored Parameters:

IT360 monitors the critical components of Hyper-V server, to detect any performance problems.The components includes, processor, memory, disk, virtual & physical network, virtual storage, etc.

In the Servers tab, click on the drop down icon. The drop down list shows the list of Virtualisation-related systems. Click on the relevant VM, from the list.

You would see the following;

To view detailed performance metrics of a Hyper-V server, click the corresponding monitor. These metrics are categorized into 6 separate tabs, for easy understanding;

3. Network Tab:

This tab provides metrics about the overall networking performance of the Hyper-V server. 

Parameter

Description

Network Traffic Stats

Network Adapter Name

The name of the network adapter of the host.

Speed The rate, at which bytes are transferred, in Mbps.
Input Traffic The number of bytes received over the adapter, in kilobytes per second.
Input Traffic Utilization The percentage of input utilization.
Output Traffic The number of bytes, sent over the adapter, in kilobytes per second.
Output Traffic Utilization The percentage of output utilization.
Network Packet Stats
Offloaded Connections The number of TCP connections (over both IPv4 and IPv6) that are currently handled by the TCP chimney offload capable network adapter.
Outbound Packets Errors The number of outbound packets that could not be transmitted, because of errors.
Outbound Packets Discarded The number of outbound packets that were chosen to be discarded, even though no errors had been detected, to prevent transmission. One possible reason for discarding packets could be to free up buffer space.
