DT EXAM
Dynatrace ActiveGate - correct answer-Dynatrace ActiveGate serves as a proxy between
Dynatrace OneAgent and Dynatrace Server. ActiveGate is highly recommended for both
SaaS and Managed deployments.
Dynatrace Managed (Managed deployments only) - correct answer-If you're setting up a
Dynatrace Managed deployment, your first step is to obtain a Dynatrace Managed license.
Following that, you can install Dynatrace Managed. Dynatrace SaaS customers should skip
this step and begin by installing ActiveGate.
Dynatrace OneAgent - correct answer-Dynatrace OneAgent is responsible for collecting all
monitoring data within your monitored environment.
Don't have access to your application's web server? Consider these other deployment
options - correct answer-If you don't have access to your web server and can't install
OneAgent you can set up agentless monitoring.
If setting up agentless monitoring isn't feasible in your environment, try the RUM browser
extension.
For applications that can't be monitored by OneAgent, like traditional rich-client applications,
digital service terminals (for example, ATMs), or smart IoT applications, use Dynatrace
OpenKit.
How does Mission Control pro-active support work? - correct answer-Dynatrace Managed
automatically solves many common maintenance and support challenges for you. With
Dynatrace Mission Control, you get fully automated management capabilities in a pro-active
way that keep Dynatrace Server secure, reliable, and up-to-date—all while saving you from
the hassles of administrative tasks like upgrades and troubleshooting. Once you've granted
the required permissions, our Mission Control team can remotely access your Dynatrace
Server to assist with upgrades and troubleshooting when you run into problems.
How Mission Control works - correct answer-To facilitate pro-active support, your Dynatrace
Server transmits status information to and from Dynatrace Mission Control. The only data
that our Mission Control team can access comes from the server component of your
Dynatrace Managed installation. At no time can our Mission Control team access your
operating system or file system.
Our goal is to provide the highest possible system uptime (> 98%) and processing rate (>
99.5%) for collected monitoring data.
What Mission Control does - correct answer-Dynatrace Mission Control is responsible for
sending
Usage and billing information
,Dynatrace Server health statistics
Once permission is granted, our Mission Control team can remotely analyze the hardware
utilization of your Dynatrace Managed installation and alert you if more resources are
required.
Dynatrace Server event tracking
Events like server starts/shutdowns, added/removed nodes, and ActiveGate registrations are
tracked automatically. Our Mission Control team can remotely analyze and address
problems or incompatibilities with your Dynatrace Server, so you don't need to track and
react to system events. If you should ever need to contact Dynatrace Support, you won't
need to collect the required log files for problem details—Mission Control gathers this data
for your automatically. To see the list of Dynatrace Server system events that are
automatically logged, click the Events tile on your Dynatrace Managed home page.
System settings
Our Mission Control team can remotely optimize your Dynatrace Managed settings to ensure
optimum performance and stability.
Software updates
Dynatrace Managed software updates are mandatory and are typically published every four
weeks. You can customize the timing of Dynatrace Managed updates (daily or weekly).
Updates are automatically communicated to your users at least 24 hours in advance.
Dynatrace Managed updates are fast and allow monitoring to continue seamlessly.
Mission Control security - correct answer-All communication with Mission Control is secure
and performed via HTTPS with browser-like certificate checks. All Dynatrace Managed
configuration changes are fully audit-logged and each remote access is logged as a
separate event (click the Events tile on your Dynatrace Managed home page to view the list
of recorded events). The Mission Control team can't access certificates or user credentials.
They also can't gain root access to any servers.
How are new problems evaluated and raised? - correct answer-Dynatrace continuously
measures incoming traffic levels against defined thresholds to determine when a detected
slowdown or error-rate increase justifies the generation of a new problem event. Rapidly
increasing response-time degradations for applications and services are evaluated based on
sliding 5-minute time intervals. Slowly degrading response-time degradations are evaluated
based on 15-minute time intervals.
Note that newly detected anomolous events in your environment..... - correct answer-....won't
necessarily result in the immediate raising of a new problem. Raised problems always
provide insight into the underlying root cause. To identify the root causes of problems,
Dynatrace analyzes the correlation of events across time, processes, hosts, services,
applications, and both vertical and horizontal topological monitoring perspectives. Only by
correlating events across time and all these monitoring perspectives can Dynatrace pinpoint
the root causes of problems. And only then will you be alerted to a detected problem. For
more details, see automatic correlation of dependent toplological incicents.
, Understanding thresholds
Dynatrace utilizes three types of thresholds: - correct answer-Automated baselines:
Multidimensional baselining automatically detects individual reference values that adapt over
time. Automated baseline reference values are used to cope with dynamic changes within
your application or service response times, error rates, and load.
Built-in static thresholds: Dynatrace uses built-in static thresholds for all infrastructure events
(for example, detecting high CPU, low disk space, or low memory).
User-defined static thresholds: With customizable anomaly detection settings (available at
Settings > Anomaly detection), you can overwrite the default static thresholds for
infrastructure events. You can also switch from automated baselining for application and
service anomaly detection to static thresholds. With static thresholds, the detected baseline
thresholds are overwritten by your custom static thresholds for individual dimensions.
What is a monitoring environment? - correct answer-Your Dynatrace monitoring environment
is where all your Dynatrace performance analysis takes place. Dynatrace OneAgent sends
all captured monitoring data to your monitoring environment for analysis. A monitoring
environment is analogous to an analysis server that provides all Dynatrace
application-performance analysis functionality, including all dashboards, charts, reports and
other tools.
What is a monitoring environment? - correct answer-Your monitoring environment resides in
the Dynatrace cloud, unless you're using our on-premises deployment option, Dynatrace
Managed. For Dynatrace Managed customers, your monitoring environment is hosted within
your own data center.
Multiple monitoring environments - correct answer-It's common to set up multiple monitoring
environments so that related entities can be grouped for discrete analysis. For example, you
might set up one monitoring environment to monitor and analyze the performance of your
production clusters. You might set up a second environment that's dedicated to the
performance of your developers' machines and a third environment for your staging servers.
How you segment your monitoring environments is entirely up to you. For details on how to
set up multiple monitoring environments, please check Can I set up multiple monitoring
environments? if you've chosen the SaaS option or How can I create and manage my
monitoring environments? for Dynatrace Managed.
Get started with Dynatrace SaaS - correct answer-Step 1: Create your Dynatrace account
Step 2: Install OneAgent and Environment ActiveGate
Step 3: Fine tune your environment
