Analytics Dashboards

The analytics dashboards display a variety of charts to provide an overview of API Gateway performance and its API usage. The data for these dashboards come from the API Gateway destination store. In API Gateway there are two types of dashboards. Each of these dashboards has various filters that can be applied as per the required metrics to be monitored.

API Gateway dashboard. Displays API Gateway-wide analytics such as Summary of APIs, API usage, API trends, the top performing API and the non-performing API analytics, audit logs, applications and package related event information. This can be accessed by expanding the menu options icon

, in the title bar, and selecting Analytics.

API-specific dashboard. Displays API specific analytics such as API invocation trends by response time, success and failure rates, API performance, consumer or application traffic for a specific API. This can be accessed from the API details page.

The dashboard displays depend on the events and metrics generated in API Gateway and their types. An event is a kind of notification or alert generated by the API Gateway Metrics and Event Notification module. Various types of event are generated based on the behavior of the transactions in the system. Events generated by API Gateway are real time events made persistent in the store and sent to configured destinations.

Transactional event : Provides a summary of each runtime transaction in the system. It is generated when a Log Invocation policy is included for the API. For example, if an API has the policy attached to it, then for every invoke the system generates a transaction event. API Gateway provides a system global policy, Transaction logging, which are pre-configured in the product. This policy is, by default, deactivated. The transaction logging policy has standard filters and a log invocation policy that logs request or response payloads to a specified destination.

Error event: Provides details of an error that occurred during an API invoke. This event is generated whenever there is an error in the system during a runtime service invocation. This is configured as part of destination configuration.

Monitoring event: Provides a summary of event details along with the breach information when there is a threshold breach in any of the configured parameters. Monitoring could be done based on various parameters such as Total Request Count, Total Success Count, Response Time, and Availability. Monitoring can be done at the consumer application level too so that each consumer can be tracked individually. These events are generated when a Monitor Service performance and Monitor SLA Policy is included for the API. In addition, the Traffic Optimization policy generates these events for every API invocation only when there is a breach in the parameters configured in the policy or once per alert interval based on the alert frequency configured in the policy.

Policy violation event: Provides a summary of the policy violations that occurred in the system. When a policy attached to an API is violated, the system generates the policy violation event for alerting the provider. The Identity and Access, Authorization, and Schema Validation policies generate these events. This is configured as part of destination configuration. In addition, the Traffic Optimization policy generates these events for every API invocation only when there is a breach in the parameters configured in the policy.

Lifecycle event: Provides a summary of the life cycle of the API Gateway instance. Whenever the instance is started or stopped, a life cycle notification is generated. This is configured as part of destination configuration.

Threat protection event: Provides a summary of the threat protection filter and rule violations. When a filter or rule is violated, the system generates the threat protection violation event. This is configured a part of destination configuration.
