The BEX KM monitors drive pools and individual tape drives using the BEX_DRIVEPOOL and BEX_DRIVE application classes. Metrics for tape drives are described below:
| • | The transfer rate for read and write operations on the tape drive are shown by the BEXDriveReadRate and BEXDriveWriteRate. |
| • | The number of errors detected in the tape drive is shown by the BEXDriveErrors parameter. If errors are detected, the parameter will be annotated with a dialog box showing the type of error detected (a hard/soft error for a read/write/seek operation). |
| • | If the tape drive needs cleaning the BEXDriveClean will go into a WARNING state. |
| • | The number of hours the tape drive has been in use is shown by the BEXDriveInUse parameter. |
| • | The number of mount operations the tape drive has performed is shown by the BEXDriveMounts parameter. |
