Below is the command issued on SUSE LINUX 11 server to run in the background in order to collect the performance data.
sar 60 > sar.output 2>&1 &
When I looked at the output(sar.output) after 10 hours, it logged only 180 entries which is equivalent to 3 hours of run. I could not see any sar process running in the background. The above command should run continuously without any interruption. Why did the process got aborted after certain period of time. Please help.
