NetWorker Activity Reporter

The NAR (NetWorker Activity Reporter) tool provides reports on Legato NetWorker activity. For example, the command:

nar -s mybackupserver -r group -c smeagol -o report.txt

provides a performance report (average backup speed) for the NetWorker client "smeagol", displaying the various groups that the client smeagol belongs to. If you add the following to your crontab file:

1 12 * * * /usr/bin/nar -o /var/nar/\%d -rgroup -n0 >/dev/null 2>&1

then NAR will build a directory with reports on your NetWorker server.

The NSRIO utility works a bit like IOSTAT, and reports samples of NetWorker device statistics. For example, the command :

nsrio -d /dev/nst0 -i 2

shows the rate (in megabyte per seconds) and the current number of sessions on the device /dev/nst0, and prints samples of these values every two seconds.
