The new FCP adapter statistics provide a variety of information about the virtual adapter (subchannel). In order to collect this information the zfcp driver is extended to query this information. The information provided by the new FCP adapter statistics can be fetched by reading from the following files in the sysfs filesystem /sys/class/scsi_host/host<n>/seconds_active /sys/class/scsi_host/host<n>/requests /sys/class/scsi_host/host<n>/megabytes /sys/class/scsi_host/host<n>/utilization These are the statistics on a virtual adapter (subchannel) level. The information provided is raw and not modified or interpreted by any means. No interpretation or modification of the values is done by the zfcp driver.
