Hello, I’m building a Dynatrace dashboard and I am confused about the built-in metrics related to errors. According to the below Dynatrace documentation [1] on built-in metrics, Dynatrace offers the following error rates for use on a Dashboard: 1. builtin:service.errors.client.rate: Failure rate (client-side errors) 2. builtin:service.errors.fourxx.rate: Failure rate (HTTP 4xx errors) 3. builtin:service.errors.server.rate: Failure rate (server-side errors) 4. builtin:service.errors.fivexx.rate: Failure rate (HTTP 5xx errors) 5. builtin:service.errors.total.rate: Failure rate (any errors) [1] [Built-in classic metrics — Dynatrace Docs](https://www.dynatrace.com/support/help/how-to-use-dynatrace/metrics/built-in-metrics) The documentation is not specified about what these errors are about, therefore I am asking here in the Community forum for clarification. My questions: - What is the difference between client-side errors and HTTP 4xx errors? - Likewise, how can I distinguish HTTP 5xx errors from server-side errors? - Are the HTTP 4xx errors part of the client-side errors, and are HTTP 5xx errors part of server-side errors? - Is the metric “Failure rate (any errors)” then the error rate when considering all 4 error categories (HTTP 4xx, HTTP 5xx, client and server errors)? Thank you for your support! Best regards, Bernhard ---

Hi [@bernhard\_s](https://community.dynatrace.com/user/28651), Could you please check this part of the documentation I think you will find the answers for your questions. [Configure service failure detection | Dynatrace Docs](https://www.dynatrace.com/support/help/how-to-use-dynatrace/services/service-monitoring-settings/configure-service-failure-detection#tabgroup--configure-failure-detection--global-settings) Best regards, Mizső ---

[@Mizső](https://community.dynatrace.com/user/47783)   - No, this does not answer my questions. BR Bernhard ---

The referenced docs page referenced by [@Mizső](https://community.dynatrace.com/user/47783) I believe does explain the difference of detected errors and how to configure them if they don’t meet your need. For example reading the explanation tells me that 500-5xx will always be interpreted as a server error. So 5xx metrics.rate is a server error while 400-4xx (yes there is a typo on that page) is a client error. Then it also says that missing HTTP response code as client-side errors or server-side. So my naiv assumption is that 4xx is everything from 400-4xx while client side or then server-side (500-5xx), respectively can be more than just the actual 4xx or 5xx errors. E.g. when you also take missing response codes into account. Answer to - What is the difference between client-side errors and HTTP 4xx errors? - Likewise, how can I distinguish HTTP 5xx errors from server-side errors? Id therefore say yes to - Are the HTTP 4xx errors part of the client-side errors, and are HTTP 5xx errors part of server-side errors? And yes to: - Is the metric “Failure rate (any errors)” then the error rate when considering all 4 error categories (HTTP 4xx, HTTP 5xx, client and server errors)? But maybe [@tom\_rothschaedl](https://community.dynatrace.com/user/8742) can cross-check this, pls.
