vfs.dev.read[sda,,avg5]

Is there a key to check the scsci disk as it is in the title? My servers have scsi controllers.

I need to check the performance of the disk. I tried the other io[disk_rblk] but even though the disk gets heavy read/write I just see a steady flat line in the graph. I am using number of disk read operations with simple and avg set.

well, io[] was 1.0 and deprecated, and docs had incorrect usage of new items...
turns out, you have to use something like vfs.dev.read[sda,operations]
