Performance metrics for ports on an XIV
You can include performance metrics for storage system ports on an XIV 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 Bandwidth Percentage
- The percentage of the port bandwidth that is used for send operations. This value is an indicator of port bandwidth usage that is based on the speed of the port.
- Port Receive Bandwidth Percentage
- The percentage of the port bandwidth that is used for receive operations. This value is an indicator of port bandwidth usage that is based on the speed of the port.
- Overall Port Bandwidth Percentage
- The percentage of the port bandwidth that is used for send and receive operations. This value is an indicator of port bandwidth usage that is based on the speed of the port.
