Observability in Azure API Management

Observability is the ability to understand the internal state of a system from the data it produces and the ability to explore that data to answer questions about what happened and why.

Azure API Management helps organizations centralize the management of all APIs. Since it serves as a single point of entry of all API traffic, it is an ideal place to observe the APIs.


Azure API Management allows you to choose to use the managed gateway or self-hosted gateway, either self-deployed or by using an Azure Arc extension.

The table below summarizes all the observability capabilities supported by API Management to operate APIs and what deployment models they support. These capabilities can be used by API publishers and others who have permissions to operate or manage the API Management instance.


For API consumers who use the developer portal, a built-in API report is available. It only provides information about their individual API usage during the preceding 90 days.

1. Optional, depending on the configuration of feature in Azure API Management

2. Optional, depending on the configuration of the gateway

3. The self-hosted gateway currently does not send diagnostic logs to Azure Monitor. However, it is possible to configure and persist logs locally where the self-hosted gateway is deployed. For more information, please see configuring local metrics and logs for self-hosted gateway
