Performance metrics for storage system ports on block servers

You can include performance metrics for storage system ports on block servers in performance reports.

Port data

You can create performance reports that include the following information:

Port Send I/O Rate (ops/s): The average number of I/O operations per second for operations in which data is sent from a port.A send operation is a read operation that is processed, or a write operation that is initiated by the port.
Port Receive I/O Rate (ops/s): The average number of I/O operations per second for operations in which the port receives data.A receive operation is a write operation that is processed, or a read operation that is initiated by the port.
Total Port I/O Rate (ops/s): The average number of send operations and receive operations per second.
Port Send Data Rate (MiB/s): The average rate at which data is sent from the port. The rate is measured in MiB per second. A send operation is a read operation that is processed, or a write operation that is initiated by the port.
Port Receive Data Rate (MiB/s): The average rate at which data is received by the port. The rate is measured in MiB per second. A receive operation is a write operation that is processed, or a read operation that is initiated by the port.
Total Port Data Rate (MiB/s): The average rate at which data is transferred through the port. The rate is measured in MiB per second and includes both send and receive operations.
Port Send Response Time (ms/op): The average number of milliseconds to complete a send operation.
Port Receive Response Time (ms/op): The average number of milliseconds to complete a receive operation.
Overall Port Response Time (ms/op): The average number of milliseconds to complete a send or receive operation.
Port Send Transfer Size (KiB/op): The average number of KiB that are transferred per send operation. A send operation is a read operation that is processed or a write operation that is initiated by the port.
Port Receive Transfer Size (KiB/op): The average number of KiB that are transferred per receive operation. A receive operation is a write operation that is processed or a read operation that is initiated by the port.
Overall Port Transfer Size (KiB/op): The average number of KiB that are transferred per I/O operation. This value includes both send and receive operations.
