Spotlight on SQL Server Enterprise 11.7 - Management Pack for SCOM User Guide

Shows the incoming and outgoing packet rates as an aggregate across all network cards for the Windows server.

Shows the total number of packets (incoming and outgoing) broken down by network card.

Shows the level of traffic being received and sent by the Windows server in kilobytes.

Shows the number of errors and retries on the network subsystem. A consistent number of retries or errors usually means one of the following:

• A network segment attached to the Windows server is over-utilized.
• There are problems with a network card, cabling or other networking device on a network segment.

Shows different graphs representing the rate at which TCP segments are transmitted or received in the Windows server.

When TCP transfers a stream data, it breaks up the stream into small segments

Shows the rates at which the fragmented packets are received and rebuilt.

When data packets are transmitted across a network via TCP/IP, they may be further fragmented en route, and need to be reassembled.

Shows different graphs representing the rate at which UDP datagrams are transmitted or received in the Windows server.

UDP (User Datagram Protocol) is an alternative communications protocol to the Transmission Control Protocol (TCP).

Unlike TCP, UDP does not provide a sequencing service, so when UDP datagrams (packets) arrive at a destination, they are reassembled into a complete message via an end-point application that is active on the port(s) specified in the datagram.

Shows the rates at which IP packets are sent, received, and routed to other destinations.

IP datagrams (packets) are the message units that are transmitted across a network (and across the Internet) via the Internet Protocol.

You can view either the IP Datagrams chart or the IP Datagrams Errors chart. Select the desired option from the drop-down menu at the top of the chart.

Shows the machines that have a connection to the Windows server, and the corresponding level of traffic (in kilobytes) being generated between the connections.

This is only for NBT (NetBios over TCP/IP) connections – that is, only Microsoft Networking connection over TCPIP.

Shows active connections made to the Windows Server by users on other systems.

Remote Desktop sessions are not shown.

Shows the resources on the Windows Server that can be shared with users on other systems

Shows the connections currently established to the shared resource selected in the Shares grid.

For this chart network traffic is defined as that passing through locations external to the Hyper-V server and the virtual machine. Network traffic passing between virtual machines on the same Hyper-V server does not count.
