What are key performance metrics? - Answer- enable you to select the ideal user experience metric for each of your applications. These metrics provide you

What are the Dynatrace key performance metrics? - Answer- - Visually complete
- Speed index
- DOM interactive
- Time to first byte
- Load event end
Describe Key Performance Metric "Visually complete". - Answer- measures how long it takes for the visible portion of each user's browser screen to fully render.
Note: The point in time at which all content in the browser's visible area is fully rendered.
Describe Key Performance Metric "Speed index". - Answer- The average amount of time before which all visible parts of a page are displayed. A low value means that most parts of a page are rendering quickly..
Describe Key Performance Metric "DOM interactive". - Answer- The amount of time it takes before a page's readiness status is set to interactive (ready to receive further user input).
Describe Key Performance Metric "Load event end". - Answer- The amount of time it takes before the load event of the current page is completed.
Describe Key Performance Metric "Load event Start". - Answer- The amount of time it takes before the load event of the current page begins.
Describe Key Performance Metric "HTML downloaded". - Answer- the amount of time it takes before the last byte of the current page is received, or before the transport connection is closed (whichever comes first).
Describe Key Performance Metric "Time to first byte". - Answer- The amount of time it takes before the first byte of a response is received from the server, relevant application caches, or a local resource.
Describe Key Performance Metric "Response end (XHR actions)". - Answer- The elapsed time from when the first byte of the server response is received until either when the last byte of the current document of the response is received or when the response completes, whichever comes first.
How database activity is monitored - Answer- Dynatrace doesn't consider methods, but rather commits, queries, and modifications related to your database services. By monitoring such calls, Dynatrace is able to deliver automatic root-cause analysis for performance problems with your database services. Dynatrace shows you which database statements are executed most often and which statements take up the most time. Dynatrace tells you if there is a correlation between the problem and any load increase on a related service, which may be the root cause of the problem.
List the "Analyze database services" - Answer- - response time
- failure rate
- throughput
- database statement executed by your applications.
- SQL queries or procedures
- SQL modifications
- SQL transactions
Why don't I see my applications or monitoring data? - Answer- - first thing you need to do is confirm that there is traffic in your web front-end processes (web server, Java, Node.js, etc). To do this, interact with one of your applications' pages to generate some traffic.
- Confirm that the RUM JavaScript tag has been correctly injected into your application's HTML.
- Confirm that the RUM JavaScript tag has downloaded correctly.
- Confirm that RUM monitoring data is being sent to Dynatrace.
How can I confirm the JavaScript tag is injected correctly? - Answer- - For standard OneAgent installations (automatic tag injection)
Search for a script that contains the string ruxitagentjs in its file name.
- For agentless monitoring (no OneAgent, no automatic injection)
Search for a script that's loaded from js-cdn.dynatrace.com (or your own CDN or domain in Dynatrace Managed; CDN is recommended) and ends with the string _bs.js.
How can I confirm that the JavaScript tag reports data to the server? - Answer- - For agentless monitoring
CORS requests to the Dynatrace infrastructure should be visible. Look for the following URL pattern: http(s)://[...].live.dynatrace.com/bf
Responses must have status 200 "OK" and response content must start with "OK"
- For automatic injection
XHR requests back to the server-side should be visible. Look for the following URL is relative to the current page location and begins with rb_
Responses must have status 200 "OK" and response content must start with **OK**
What is "Monitor CORS requests" - Answer- Web requests can only be linked to user actions when cookies are available. In the c [Show Less]
