ANSWERS
HTTP monitor - CORRECT ANSWER consists of one or multiple HTTP(S) requests (for
example, GET, POST, HEAD requests). Each request executed by an HTTP monitor
equates to one synthetic request.
Custom vs built-in metrics - CORRECT ANSWER All metrics that are automatically
detected and analyzed following installation of One Agent are considered to be built-in
metrics. Built-in metrics cover a wide range of supported technologies, including Apache
Tomcat, NGINX, Couch base, RabbitMQ, Cassandra, Jetty, and many others.
A custom metric is defined as a new type of metric that offers a user-provided metric
identifier and unit of measure. The semantics of custom metrics are defined by you and
aren't included in the default One Agent installation. Custom metrics are sent to
Dynatrace through various interfaces including the Dynatrace API, OneAgent,
ActiveGate, and JMX/PMI extensions. Following the definition of a custom metric, the
metric can be reported for multiple monitored components. Each component's custom
metric results in a separate timeseries.
ActiveGate extensions - CORRECT ANSWER with ActiveGate extensions, you can
extend Dynatrace monitoring to any remote technology that exposes an interface,
where OneAgent installation isn't an option. For example, PaaS technologies, network
devices, or cloud technologies. ActiveGate extensions (aka Remote Plugins) are
executed on ActiveGate and can acquire metrics and topology from remote sources,
fully integrating new-technology monitoring into Dynatrace Smartscape and problem
detection. You need some Python expertise to develop ActiveGate extensions.
Dynatrace OneAgent - CORRECT ANSWER responsible for collecting all monitoring
data within your monitored environment. A single OneAgent per host is required to
collect all relevant monitoring data—even if your hosts are deployed within Docker
containers, microservices architectures, or cloud-based infrastructure.
A single instance of OneAgent can handle monitoring for all types of entities, including
servers, applications, services, databases, and more. OneAgent gives you all the
operational and business performance metrics you need, from the front-end to the back-
end and everything in between—cloud instances, hosts, network health, processes, and
services. OneAgent discovers all the processes you have running on your hosts. Based
on what it finds, OneAgent automatically activates instrumentation specifically for your
unique application stack. It also injects all tags required for user-experience monitoring
