A customer asked us for fine grained performance data, so I ran
"/usr/lib/sa/sadc -F -L 10 17280 /tmp/sadc.out" and verified that the
file was updated every 10 seconds. The resulting output file is 37MB.
I then wanted to use sar to convert the sadc file to a sar file, but
I'm having problems doing so. Using "sar -A -i 10 -f /tmp/sadc.out |
head -n 20" returns:

Average: 0.95
instead of the 10 second intervals I was expecting. Does anyone know
how to extract the data in sar format in 10 second intervals?
Kind regards,
Herta
