RH442 is rightly called the elephant in the room by most of the learners.

It teaches senior Linux system administrators the methodology of performance tuning. This course discusses system architecture with an emphasis on understanding its implications on system performance, performance adjustments, open source benchmarking utilities, networking performance, and tuning configurations for specific server use cases and workloads.

Hi folks,
Trying the community chat feature here.

I just failed task #3 in Lab Selecting Performance Monitoring Tools, as I did not `cp /usr/lib/systemd/system/sysstat-collect.timer \
/etc/systemd/system/sysstat-collect.timer`. I chose to create an overwrite file in `/etc/systemd/system/sysstat-collect.timer.d/timer.conf` with the following content instead:

~~~
[Timer]
OnCalendar=*:00/01
~~~

Did I fail only because of the grading script not recognizing overwrite files? How would this be in the EXAM?
