The SMB Direct Connection performance counter set consists of counters that measure connection activity. A computer can have multiple SMB Direct connections. The SMB Direct Connection counter set represents each connection as a pair of IP addresses and ports, where the first IP address/port represents the connection's local endpoint and the second IP address/port represents the connection's remote endpoint.
'Bytes RDMA Read/sec is the rate at which bytes are being transferred by RDMA read operations. This counter displays the difference between the values observed in the last two sample intervals, divided by the duration of the sample interval.'
'Bytes RDMA Written/sec is the rate at which bytes are being transferred by RDMA write operations. This counter displays the difference between the values observed in the last two sample intervals, divided by the duration of the sample interval.'
'Bytes Received/sec is the rate at which data is being received from the peer. Data that is directly read from the peer via RDMA read operations is not counted. This counter displays the difference between the values observed in the last two sample intervals, divided by the duration of the sample interval.'
'Bytes Sent/sec is the rate at which data is being sent to the peer. Data that is directly written to the peer via RDMA write operations is not counted. This counter displays the difference between the values observed in the last two sample intervals, divided by the duration of the sample interval.'
'RCQ Notification Events/sec is the rate at which SMB Direct is being notified that RQ work requests have completed to the RCQ. This counter displays the difference between the values observed in the last two sample intervals, divided by the duration of the sample interval.'
'RDMA Registrations/sec is the rate at which memory is being registered as the source or destination for an RDMA data transfer. This counter displays the difference between the values observed in the last two sample intervals, divided by the duration of the sample interval.'
'Receives/sec is the rate at which SMB Direct data packets are being received from the peer. This counter displays the difference between the values observed in the last two sample intervals, divided by the duration of the sample interval.'
'Remote Invalidations/sec is the rate at which local RDMA registrations are being remotely invalidated by the peer. This counter displays the difference between the values observed in the last two sample intervals, divided by the duration of the sample interval.'
'SCQ Notification Events/sec is the rate at which SMB Direct is being notified that SQ work requests have completed to the SCQ. This counter displays the difference between the values observed in the last two sample intervals, divided by the duration of the sample interval.'
'Sends/sec is the rate at which SMB Direct data packets are being sent to the peer. This counter displays the difference between the values observed in the last two sample intervals, divided by the duration of the sample interval.'
'Stalls (RDMA Read)/sec is the rate at which RDMA reads stalled due to a limit on the number of simultaneous RDMA read operations per connection. This counter displays the difference between the values observed in the last two sample intervals, divided by the duration of the sample interval.'
'Stalls (RDMA Registrations Resources/sec) is the rate of memory registration stalls due to insufficient RDMA registration resources. This counter displays the difference between the values observed in the last two sample intervals, divided by the duration of the sample interval. This counter displays the difference between the values observed in the last two sample intervals, divided by the duration of the sample interval.'
'Stalls (Send Credit)/sec is the rate at which transmission of SMB Direct packets stalled due to an insufficient number of send credits. This counter displays the difference between the values observed in the last two sample intervals, divided by the duration of the sample interval.'
'Stalls (Send Queue Capacity)/sec is the rate at which RDMA network interface requests stalled due to insufficient send queue capacity. This counter displays the difference between the values observed in the last two sample intervals, divided by the duration of the sample interval.'
'The Name property defines the label by which the statistic or metric is known. When subclassed, the property can be overridden to be a Key property. '

The SMB Direct Connection counter set represents each connection as a pair of IP addresses and ports, where the first IP address/port represents the connection's local endpoint and the second IP address/port represents the connection's remote endpoint.'
