I have a backup spooling onto a DLT drive. Is there any tool that will let me monitor the data throughput on the device?
Throughput on a tape drive is very variable, depending on how you are writing/reading the data to it.
So for some meaningful numbers, you would need your backup solution to provide them.
I'm just looking for raw bps flowing to the device. I don't really care about compression and such at the moment, I just want a rough idea of what the drive is doing.
There is no such thing. You "raw bps" will vary greatly depending on your blocksize and other factors.
I don't follow. The backup program is writing data to the device. Regardless of how complex that data stream is, there is a specific amount of data that is transmitted in a given period of time.
This would be like sticking a meter inline on an ethernet cable and simply counting bits.
There may or may not be a tool to do this and it may or may not be a useful measurement, but it should be possible.
