Most Active Ports report
Shows a chart of the 20 ports that are most active, and details for all ports, for a time period that you specify. Use the report to analyze the performance of ports.
Charts
The bar chart shows the most active
ports on storage systems. By default, ports are sorted by the I/O
rate.
Tip: To change the sort order,
select a value from the Sort Order list.
Report output
The information that is provided about the most active ports is as follows:
- Storage System Name
- A user-defined name of the storage system. If a name was not defined, IBM Spectrum Control shows the name that was defined when the storage system was added for monitoring.
- Storage Port Name
- The name that was assigned to the storage port when the storage system was added to the system.
- Storage System Port Location
- The physical location of a port on DS8000 storage systems and XIV systems. For all other systems, this property shows the WWPN of the port.
- Storage System Configuration
- Shows whether a storage system is configured as back-end storage
or configured to virtualize back-end storage. If this value is
Storage System, the storage system is configured as back-end storage. If this value isStorage Virtualizer, the storage system is configured to virtualize back-end storage. - Overall Port Response Time (ms/op)
- The average number of milliseconds to complete a send or receive operation.
- Total Port I/O Rate (ops/s)
- The average number of send operations and receive operations per second.
- 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.
- 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.
