In Dynatrace, what signifies that a request has been processed successfully?

A response code of 200 indicates that the request has been processed successfully and that the server has returned the requested resource. This status code is part of the HTTP/1.1 standard and signifies that everything worked as expected. When a client, such as a web browser or an API consumer, receives a 200 response code, it confirms that the request was received, understood, and accepted by the server.

In contrast, other status codes indicate different statuses of the request. A response code of 204 signifies that the server successfully processed the request but is not returning any content, which may not necessarily be perceived as a "successful request" in all contexts. Response codes such as 400 and 404 indicate errors; a 400 response code means that there was a bad request from the client due to malformed syntax, while a 404 response code indicates that the server cannot find the requested resource. These codes clearly do not represent a successful request.

Understanding these response codes is crucial for managing and monitoring application performance and behavior in Dynatrace, as they provide essential insights into the health of services and the user experience.
