You can use centralized logging to easily enable mustGather traces, perform a per-request trace analysis, and follow the flow of a request through both the ODR and application server tiers.
Using centralized logging, you can enable tracing based on the type of problem that you experience, for example, 503 HTTP response codes. With centralized logging, specific types of mustGather documents can be identified by predefined strings. Some examples of predefined mustGather documents include application editioning, 404 error and 503 response codes, health monitoring, and more.
You can also enable rule-based tracing which allows you to trace requests based on specific rules.
