>> Hey there, Cybrarians. Welcome back to
00:00
the Linux plus course here at Cybrary.
00:00
I'm your instructor, Rob Goelz.
00:00
In today's lesson, we're going to be
00:00
discussing orchestration and monitoring.
00:00
Upon completion of this lesson,
00:00
you are going to be able to
00:00
understand the orchestration components and processes,
00:00
as well as differentiate between
00:00
agent and agentless monitoring tools.
00:00
System administration has largely moved on
00:00
>> from where we once were where we were only
00:00
>> managing a handful of servers.
00:00
Nowadays, systems administrators often
00:00
manage hundreds or even thousands of servers,
00:00
and each of these servers can have
00:00
varying levels of complexity
00:00
>> and different requirements.
00:00
>> When we're trying to deal with
00:00
>> that complexity in scale,
00:00
>> system administrators now use orchestration tools.
00:00
Orchestration simplifies those complex tasks
00:00
and automation is part of this.
00:00
It configures processes to occur automatically.
00:00
In this module, we're going to
00:00
cover orchestration concepts,
00:00
tools, and their purpose,
00:00
but we won't be diving into setup, configuration,
00:00
or administration because that's
00:00
beyond the scope of the Linux plus exam.
00:00
Throughout this module, we will cover
00:00
the orchestration components and processes.
00:00
Components include things like monitoring,
00:00
which is this lesson, as well as
00:00
procedures and attributes, as well as inventory.
00:00
Orchestration processes include
00:00
>> infrastructure automation
00:00
>> with infrastructure as code,
00:00
automated configurations, and build automation.
00:00
Orchestration monitoring tools help to track
00:00
system health and may also provide
00:00
>> logging and reporting.
00:00
>> There are generally two types of monitoring tools.
00:00
There are agent monitoring tools.
00:00
These require software installations
00:00
on a system or in a container.
00:00
This software in agent collects monitoring data
00:00
>> and then transfers it back to a centralized server.
00:00
>> Now that centralized server can provide reporting,
00:00
alerting, and also possibly analysis of that data.
00:00
By comparison, we also have agentless monitoring tools.
00:00
In this case, no software is installed.
00:00
Instead, preexisting system utilities or
00:00
software are used to get the data that we need
00:00
for monitoring and the monitoring server
00:00
may receive data from
00:00
the system or it may query
00:00
the system using those preexisting system utilities.
00:00
In this lesson, we covered the evolving role
00:00
>> of the system administrator
00:00
>> and the part orchestration plays,
00:00
>> we talked about the orchestration components
00:00
and processes that leverage orchestration,
00:00
and then we talked about
00:00
orchestration monitoring tools such
00:00
as agent monitoring and agentless monitoring tools.
00:00
Thanks so much for being here,
00:00
>> and I look forward to seeing you in the next lesson.
