Wow.
It has been quite a long initial section
in which we learned about
various troubleshooting methods and tools
we will need to leverage for the rest of this course
and also to succeed in the exam
and troubleshooting in general.
And to review, we learned the troubleshooting.
So if you need a refresher,
we began by addressing the troubleshooting mindset
where we should stay calm, gather information,
hypothesize, and then try a fix
before we began to learn the various tools
we have to gather system information,
and there's quite a number there.
I'm not going to read them all out to you,
but once we learned some basic system information commands
we then followed this up
by exploring Red Hat documentation.
Specifically, we made sure
we had a developer account created,
and then we learned how to find more information on the CLI
with things like help, RPM,
/usr/share/docs, and yum commands.
We then began to explore monitoring
with our Monitoring and Performance Co-Pilot set up lesson
before we learned how to use various PCP tools,
such as pmstat, pminfo, pmval and pmrep.
Following this, we began to learn our logging basics
specifically with regards to rsyslog and journald.
And then, we learned how to set up a remote logging server,
as well as make sure our other servers
are actually forwarding our logs to our remote host.
In our next section,
we are going to look at how to troubleshoot boot issues,
which is going to be a little lower level
than anything we've done thus far.
I'm excited about it, and if you are too,
go ahead and move on to that next section,
or you can take the reinforcement quiz for this one
to make sure you have the basic concepts
of this section down.
Thank you for watching.
