00:00:06,310 --> 00:00:09,830
- Ensuring high availability,
performance, security

2
00:00:09,830 --> 00:00:13,060
and cost-effectiveness
requires instrumentation,

3
00:00:13,060 --> 00:00:15,920
and not just the ability
to evaluate the past,

4
00:00:15,920 --> 00:00:18,860
but more importantly
the ability to respond

5
00:00:18,860 --> 00:00:21,160
to changing conditions
now, in near real time.

6
00:00:22,341 --> 00:00:24,340
In this lesson, we will review monitoring

7
00:00:24,340 --> 00:00:27,240
and log collection,
user activity tracking,

8
00:00:27,240 --> 00:00:29,110
inventory and change tracking,

9
00:00:29,110 --> 00:00:32,260
as well as tools to help
build a more secure approach

10
00:00:32,260 --> 00:00:33,843
to configuration management.
