Low Latency Workloads Management and Operations
Applies To: Windows Server 2012
New Performance Counters
Following are some of the new performance counters for Windows Server 2012.
UDP Datagram Loss
Windows Server 2012 includes new performance counters that make it easier to measure UDP datagram and multicast receive loss due to insufficient socket buffering. If UDP datagrams or multicast datagrams arrive more rapidly than the receive application can process them, or if the application has not specified sufficient receive socket buffering, these counters record the number of datagrams that are dropped and the number of datagrams that are dropped per second. The counters are part of the Microsoft Winsock BSP counter set in performance monitor.
This new performance counter provides the total number of rejected TCP connections, and the rate of rejected TCP connections per second. The counters are part of the Microsoft Winsock BSP counter set in performance monitor.
These new performance counters allow you to track NetworkDirect (RDMA) activity, including traffic rates, errors, and control plane activity.
Per Processor Network interface card Activity
These new performance monitor counters allow you to monitor how RSS is distributing the workload across multiple cores, automatic rebalancing of workloads, and RSC packets coalescing activity.
NUMA systems synchronization
NUMA systems synchronization performance monitor counters track lock contention and related information, such as the generation of inter-processor interrupts (IPIs), to simplify performance monitoring of NUMA systems.
Windows PowerShell management of networking features
Windows PowerShell now supports a wide variety of network configuration tasks and management tasks on both local and remote computers, including:
Networking stack configuration
Network interface card configuration
Windows Firewall configuration
Network interface card teaming configuration
Because it is now possible to examine and manage these parameters locally and remotely, Windows PowerShell makes it much easier to ensure that large server installations are correctly and consistently configured using scripts and automation.
