11.10.a sar

with a default Ubuntu 16.04 setup (and the LFCS VM) statistics collection is disabled and executing "sar" will result the message below. 

 


student@ubuntu:~$ sudo sar Cannot open /var/log/sysstat/sa25: No such file or directory Please check if data collecting is enabled

I would suggest  adding  a comment in the course that one  needs  to enable it first in /etc/default/sysstat like so:


ENABLED="true"

    Hi Jengel,

    Yes, and also restarting the service or rebooting is neccesary to get sar working. I'm going to check if we can add this information.

    Thanks,

    Luis.
