Adapter Cards Counters

Linux Kernel Upstream Release Notes v6.5

Adapter cards counters are used to provide information on Operating System, application, service or the drivers' performance. Counters can be used for different system debugging purposes, help to determine system bottlenecks and fine-tune system and application performance. The Operating System, network, and devices provide counter data that the application can consume to provide users with a graphical view of the system’s performance quality.

WinOF-2 counters hold the standard Windows CounterSet API that includes:

  • Network Interface

  • RDMA activity

  • SMB Direct Connection

Mellanox WinOF-2 Port Traffic counters set consists of counters that measure the rates at which bytes and packets are sent and received over a port network connection. It includes counters that monitor connection errors.

Mellanox WinOF-2 VF Internal Traffic Counters are relevant for Physical Functions ONLY.

Mellanox WinOF-2 VF Internal Traffic Counters set consists of counters that measure the rates at which bytes and packets are sent and received over each core of a virtual port that is bound to a virtual PCI function.

This set is available only on hypervisors, and each virtual network adapter should be allowed to update its counters by using the mlx5cmd tool.

Warning

The virtual network adapter driver should support internal traffic counter set exposure, to make it available on hypervisor.

Warning

These counters are relevant only for ETH ports.

Controlling VF Internal Traffic

VF Internal Traffic Counters can be controlled using the mlx5cmd.exe tool. The tool enables the user to make the virtual network adapter's traffic counters per core available or unavailable for performance monitoring consumers.

Usage:

mlx5cmd.exe -VfStats -name <adapter> -vf <virtual function ID> [-register -rate <in 100 mSec.> | -unregister]

Detailed usage:

mlx5cmd.exe -VfStats -hh


Warning

These counters set is relevant only for ETH ports.

Warning

Mellanox WinOF-2 Rss counters may have performance impact when they are active.

Mellanox WinOF-2 Rss Counters set provides monitoring for hardware RSS behavior. These counters are accumulative and collect packets per type (IPv4 or IPv6 only, IPv4/6 TCP or UDP), for tunneled and non-tunneled traffic separately, and when the hardware RSS is functional or dysfunctional.

The counters are activated upon first addition into perfmon, and are stopped upon removal.

Setting "RssCountersActivatedAtStartup" registry key to 1 in the NIC properties will cause the Rss counters to collect data from the startup of the device.

All Rss counters are provided under the counter set “Mellanox Adapter Rss Counters”.

Each Ethernet adapter provides multiple instances:

  • Instance per vPort per CPU in HwRSS mode is formatted: <NetworkAdapter> + vPort_<id> CPU_<cpu>

  • Instance per network adapter per CPU in native Rss per CPU is formatted: <NetworkAdapter> CPU_<cpu>

Mellanox WinOF-2 Receive Datapath

Description

Cpu Number

The CPU where the driver process the queue completions.

Drops due to invalid packet size

Advanced when a packet is received with <A> size that is larger than the maximum MTU size allowed, which is the max size HW supports. The value can be checked using the NDIS miniport adapter general attributes struct in the field MTuSize.

Number of receive buffers posted

When this counter is not advancing, the SW/HW might be stuck. Meaning, either the SW is not processing the receive requests or the HW is not using the post receives. To check the state of WQ/CQ, check the error events log messages.

Average packet count per indicate

The average of the handled send packets per indicate calls to NDIS. The average is the number of packets completed /number of indicates to NDIS.

Packets in low resource mode

When a forced low resource (Regestry ForceLowResourcesIndication is 1, when the default is 0) or the number of outstanding post receive is lower than the minimum number of RFDs configured (Regestry is NicMinRfds).

Packets processed in interrupt mode

The number of packets indicated to NDIS during interrupt. The counter progresses as the argument “NumberOfNetBufferLists” in the function "NdisMIndicateReceiveNetBufferLists" progresses when it is called during interrupt handling.

Packets processed in polling mode

The number of packets indicated to NDIS while in polling mode.

Consumed max receives

Number of times the driver processed the number of packets that is higher than the maximum calls to NDIS Indicate (the value shown in REgestry MaxCallsToNdisIndicate). When this counter progresses, the driver stops processing any more packets.

Note: The counters “Packets processed in polling mode” and “Packets processed in interrupt mode” also progress accordingly.

Number of traffic profile transitions

Number of times the core’s Receive Queue changed traffic Latency/ Throughput.

DpcWatchDog (SingleDpc) Starvation

The number of times the driver had watchdog starvation during DPC and re-submitted a DPC. When this counter progresses, DPC does not process any packets, meaning counters 6-10 will not progress.

DpcWatchDog (TotalDpc) Starvation

The number of times the driver had watchdog starvation during DPC and moved to. When this counter progresses, DPC does not process any packets, meaning counters 6-10 will not progress.

Drops due to completion queue errors

The number of Receive Drops Due To Cqe Errors.

Interrupts on incorrect cpu

The number of received interrupts on a wrong CPU. In this case, the driver re-submits a DPC on the correct CPU.

Number of interrupts

Number of Receive Datapath interrupts.

Strided Wqes

The number of Wqes that its strides are consumed by the HW. They should progress only if StridingRQ feature is enabled (check in Regestry StridingRqEnabled).

Counters: For every N > 0 packets received, the packetsCounter should be incremented by N. The wqe counter can be incremented by [upper bound(N/number of strides in wqe) ,N].

Ecn Marked Packets (Ipv4)

The number of times the driver marked an IPv4 packet with ECN.

Ecn Marked Packets (Ipv6)

The number of times the driver marked an IPv6 packet with ECN.

Packets processed in NDIS poll mode

When the feature is enabled, counter for “Packets processed in Interrupt mode” or “Packets processed in poll mode” are not counters incremented.

Mellanox WinOF-2 Transmit Datapath counters set provides queue counters per transmit. These counters are available in Native, VMQ and SR-IOV mode.

  • <NetworkAdapter> + SqNum_<num>

  • <NetworkAdapter> + vPort_<id> + SqNum_<num>

Warning

These counters set is relevant only for ETH ports.

Description

Cpu Number

Drops due to invalid packet size

Number of packets with invalid size, “OS call to build SGL failed” counter should also progress in this case.

Number of packets posted in bypass mode
