Cannot open /var/log/sysstat/sa08: No such file or directory

If you are trying get sar working you might get this error message: “Cannot open /var/log/sysstat/sa08: No such file or directory”.  Essentially, you need to enable data collection. You do this by editing /etc/default/sysstat nano /etc/default/sysstat Then change: ENABLED=”false” to ENABLED=”true” Hope this helps someone.
