Does anyone know a way, (other than using SystemTap + iostat-scsi.stp script), to get Tape Drive performance statistics?
Server: Red Hat Enterprise Linux Server release 5.7 (Tikanga) Kernel 2.6.18-274.12.1.el5 on an x86_64
Attached Tape Devices: Number model SN HBA SCSI FO Path 0 ULT3580-HH5 1068028623 qla2xxx 1:0:0:0 NA 1 ULT3580-HH5 1068030139 qla2xxx 2:0:0:0 NA
I want to get throughput information out of these tape drives.
In AIX, you can just do iostat -p and get that information (assuming atape driver is installed). There doesn't seem to be anything like that for Linux.
Anyone know of anything?
(I don't use SystemTap + iostat-scsi.stp script because it's not meant for production. It's known to cause kernel dumps and crash systems.)
