Hello and welcome to the prep course
for the Red Hat Certified Specialist
in Linux Diagnostics and Troubleshooting.
And this section of the course
covers the understand and employ general methods
for troubleshooting exam objective.
So we're going to take a moment
to look at how our lessons for this section map back
to our exam objectives,
and then we're going to talk a little bit
about the environment you need
to proceed with this section.
So in this section, we are going to cover everything
under the general methods
for troubleshooting overall objective.
And this includes how to gather system information.
This includes methods of consulting our documentation.
This includes methods of monitoring our systems,
as well as sending all of our logs to a centralized host.
So we have a one-stop shop
to look at all of our historical logs.
Now with regard to these subobjects
and the lessons themselves.
We will learn how to gather system data
in the gather system data lesson.
We will learn how to consult our docs
in both the Red Hat documentation
and finding information on the CLI.
We will discover how to monitor our systems,
predominantly with Performance Co-Pilot
and we'll tackle that in 2 lessons,
both a setup and a using lesson.
And then finally, we're going to figure out
how to set up a centralized logging host,
but first, we're going to review our log basics
and then we're going
to actually get our remote logging set up.
And each of these objectives
also has an associated lab, although I will note
in this particular section,
the 2 initial objectives
are condensed into a single lab.
So before you begin delving into our next lesson,
I also want to address the environment we're going
to be using for this section of the course.
As noted in our previous section,
the exam uses Red Hat Enterprise Linux 8.4,
and we can use the Red Hat Enterprise 8 cloud server
located in our Cloud Playground
if you have access to that.
The smallest size server is perfectly acceptable there.
Finally, if you do not have access to our cloud Playground
or you would rather simply work on your own computer,
you can skip to the Red Hat documentation lesson
where you'll learn
how to create a Red Hat Developer account,
which will then give you access
to a Red Hat Enterprise Linux 8.4 image
that you can then download and provision
with your favorite virtualization software.
So once you have that server spun up,
feel free to move on to the next lesson
where we're going to talk a little bit
about the mindset you should have
before you begin troubleshooting.
I'll see you in the next lesson.
