ziorep_utilization - Report on utilization details

Edit online

Use the ziorep_utilization command to produce a report on the usage of FCP resources. Use the .log file from ziomon as input.

There are two different reports available. The first report provides information on the physical adapters. This report includes usage statistics of the card's bus, CPU, and overall utilization.

The second report provides various metrics on the virtual adapter. This report includes statistics on the Queued Direct I/O (QDIO) queue that is used to transfer data between the Linux system and the FCP adapter. Statistics that are given are average and maximum utilization in each interval and the number of instances when the queue was full.
