Hardware Counters for RDMA Send and Receive Operations

Infrastructure & Networking Adapters and Cables Ethernet Adapter Cards

Hello everyone,

I’m interested in monitoring RDMA operations such as SEND, RECV, READ, WRITE, and ATOMIC. I’ve found that hardware counters are available for tracking READ, WRITE, and ATOMIC operations, as described in the article Understanding Mellanox ConnectX-5 Linux Counters and Status Parameters.

My question is whether similar hardware counters exist for tracking SEND, RECV operations. If so, I’d like to know where to find them and how to access them. Any insights or resources on this topic would be greatly appreciated. Thank you!
