Netbackup 8.1.1 write speed to lto7 missing KB/sec

Hi,

i'm trying to figure out a quick way to determine what the transfer speed is to connected LTO7 drives.

The activity monitor shows me this kind of info, but only for backups to disk.  The dssu jobs (which ofcourse reflect the speed to tape) have this KB/Sec field always empty (no difference if it's the parent or child dssu).  Only thing i can do right now is look at the detailed status of a terminated job and do the math myself.

    On the media server open the bptm log for given date and grep it for Kbytes/sec.... if you do know PID of bptm you are interested with seeing this speed grep it twice for PID|grep Kbytes/sec to see it :)

    ie PID= 307370 

    grep 307370 root.103018_00001.log|grep Kbytes/sec
