What is a Private Synthetic test?

They are used to execute browser and HTTP monitors from your own infrastructure. Can have multiple ActiveGates installed on private location, and are used for failover and load balancing. If the system gets wiped, the locations will still be there, but the ActiveGate will be gone and need to be recreated. If the location gets wiped, the monitors will still be available, but the private location will need to be added back in.

What is resource Problem?

When a shortage of a resource in your monitored environment is detected. i.e. CPU, memory

What is a bounce?

When a user only does one action then leaves the page.

Injection vs. Instrumentation

When you install OneAgent, the Process Agent will look for running processes that we support. If it detects one, it will inject into it. Meaning it will load the special agent into the running process. When the process starts, the special agent is running in that process. Then the special agent (specific to a given technology) will try to do instrumentation. The sensors in the special agent will look for metrics to report back to Dynatrace.

What does Automatic injection work with?

Works on the JVM based on the servlet specification, Apache, IIS, Nginx, Node.js

What can you do to change how process groups are detected?

You can create your own process group detection rules.

Request Attributes

You can define certain request attributes to allow for filtering, sorting, and searching in the Dynatrace dashboard.

Tagging and Alerting

Which of the following are benefits of Dynatrace database monitoring?

You can see how much load is placed on your database by individual services You can find expensive database calls, for example those that read a lot of data You can find out which services talk to each database most frequently. See which users execute SQL statements

What is a drawback to Agentless?

You have to manually insert the tag into each single page in the application you want to monitor

How do you configure agentless RUM for an application?

You manually insert a JavaScript tag or code snippet into each of your application's pages

Are Managed cluster updates required?

What are the options for agentless injection?

•CDN - JS-File is loaded from the Dynatrace CDN •On the server - OneAgent writes the JS-Script to a file on the filesystem (full agent --> only parts are injected) •In-line - add full code manually in-line. No JS-File loaded (to avoid negative impact on Google PageSpeed results)

Describe Manual/Agentless Injection (RUM)

•Customer adds JS tag on their own - no OneAgent needed •Correlation of server side web requests is not possible •JS tag (code) defines the application •JS tag (JS snippet) + JS library (JS agent) •Inline Dynatrace JS code

Benefits of Managed Offering

•Full control of data •Self monitoring built-in No worries about patching, upgrading, troubleshooting, monitoring or failover

Describe Automatic agent injection (RUM)

•HTML is delivered via a OneAgent monitored server •JS tag is auto injected by the OneAgent •Correlation of server-side web requests •Application rules and injection rules can be applied
