Application - Correct AnswerA web application consists of web pages that are served by web servers and web containers, for example Tomcat. A web or mobile application is built upon services that process requests like web requests, web service calls, and messaging. Within Dynatrace, the term application refers to the front-end part that you can access via a browser or a mobile app.
Dynatrace monitors all of your application's services, processes, and infrastructure. By evaluating all components collectively, Dynatrace pinpoints exactly how each service contributes to the performance of your application. For example, in Java monitoring, the host, JVM, and processes are seen as a whole.
Dynatrace monitors all the individual components that applications are built upon: web requests, database requests, processes, services, and more. It's these individual components working together that collectively deliver what your end users view as a complete application. Dynatrace identifies and tracks each of these individual application components at a highly granular level. Dynatrace doesn't simply identify that a service is running on a server in a process but rather identifies all the details of these components. For example, Dynatrace can show you which of your web services is running on your Tomcat application server and how your Tomcat server's performance is affected by its host, or even your VMware vCenter server. In this way, Dynatrace gives you insight into the performance of your unique application stack, including all its components and connections.
Application score - Correct AnswerApplication scores are based on application Apdex ratings. In brief, the Application score is the average of your application Apdex value and the percentage of user actions that are not affected by problems.
Best way to tag entities - Correct AnswerBegin by enriching the existing domain knowledge that's available to Dynatrace with metadata that you provide. This gives you the flexibility to define tags in Dynatrace via auto tagging based on metadata.
Tags in Dynatrace
Can be changed without changing the deployment itself.Aren't dictated by an external system that you may not control.Tags can have a key/value structure. For example, you can define a tag with key SecurityIsolationLevel that has a different value for different entities. Once a tag and its rules are defined, Dynatrace will apply the tags to new entities automatically.

You may have existing tags in 3rd-party systems that you rely on and that you want to ensure are the same across your organization in an automated fashion. Dynatrace recommends providing such tags via the different meCorrect Answerat the time of deployment (Kubernetes annotations, Cloud Foundry tags, AWS tags, environment variables) or set up an integration to send them via the Dynatrace API. These tags will be "read only" in Dynatrace and therefore you won't be able to configure them via the UI.
Browser clickpath - Correct AnswerA simulated user visit that monitors your application's business critical workflows. Use the Dynatrace recorder to record an exact sequence of clicks and user input that you're interested in monitoring for availability and performance. Once you've captured the mouse clicks and additional user actions that you want your browser clickpath to include, your synthetic monitor runs automatically at regular intervals to test your site's availability and functionality.
Browser monitor - Correct AnswerThe equivalent of a simulated user visiting your application using a modern web browser. Browser monitors can be configured to run from any of our global locations at a frequency of up to once every 5 minutes. Browser monitors alert you when your application is inaccessible from the Internet or when baseline performance degrades significantly.
Can I set up multiple monitoring environments? - Correct AnswerYou may want to set up separate Dynatrace monitoring environments that are dedicated to the monitoring of your organization's development, staging, and production environments. Or possibly you want to maintain a separate monitoring environment for each of your organization's data centers. For these reasons and more, Dynatrace allows you to monitor multiple environments simultaneously with a single Dynatrace account.
The data from each additional monitoring environment you create are separated from the monitoring data that are collected from your other environments. It's easy to switch between monitoring views for separate environments to track the performance and availability of each environment. In addition to sharing the same Dynatrace account, each monitoring environment also shares the same user base and other account settings.
If you're interested in setting up additional monitoring environments, please contact Dynatrace Sales.
Cluster - Correct AnswerThe Dynatrace monitoring infrastructure. A cluster contains one or more cluster nodes that are set up using the Dynatrace Managed installer. After successful installation, each Dynatrace Managed cluster node runs a Dynatrace Server, an ActiveGate, and one instance of Cassandra, Elasticsearch, and NGINX. Each cluster also provides a web-based management interface called a Cluster Management Console.

Cluster ActiveGate - Correct AnswerA Dynatrace component that provides secure and reliable communication with cloud-based Dynatrace cluster nodes. It is downloaded from your Dynatrace Managed cluster and installed within your infrastructure. Similar to a proxy, ActiveGate reduces bandwidth requirements by encrypting and compressing network communication. It also provides monitoring of virtual infrastructure. Stopping or disabling ActiveGate reduces the monitoring capabilities of hosts that use a Cluster ActiveGate to communicate with Dynatrace clusters.
Cluster Management Console (CMC) - Correct AnswerThe web-based user interface
that manages a single Dynatrace Managed cluster. The CMC allows you to:
View the deployment status and configure your Dynatrace Managed cluster.
Manage cluster nodes and ActiveGates.
Manage your monitoring environments.
Create user accounts and groups.
View licensing information and consumption status.
View audit log and cluster events.
Configure Apdex settings - Correct AnswerTo configure your application's Apdex settings, including timing thresholds, go to Settings > Monitoring overview > Applications and select your application. Then go to User actions(looks like now in "General")
Crash analysis - Correct AnswerDetermining the root causes of a process crash.Dynatrace accelerates crash analysis by providing a process crash entry for each affected process and monitored host. Details available for crash analysis may include a native core dump, a Java core dump, or an abnormal program exit due to exceptions.Dynatrace also provides access to additional crash artifacts, such as hs_err_pid files for Java crashes, text files providing Linux and Windows core dump analysis, and files containing the .NET, Java, or Node.js exceptions that are potentially responsible for crashes.
Create user-generated access tokens - Correct AnswerTo generate and manage access tokens
Log into your Dynatrace environment and from the navigation menu click Settings > Integration.Select Dynatrace API, Platform as a Service, or Dynatrace modules to generate a token for the Dynatrace API, a token for PaaS, or a token for DCRUM or Synthetic.
Click the Generate token button, then type a meaningful token name in the text field.
