API Usage

The number of API requests issued within a specified time range, and details of each of the requests.

• The numbers of successful requests and failed requests by operation.
• Detailed information about the requests, such as request time, request ID, HTTP method, track ID, tracing identifier, and the path of each request.

Note that the Track ID column displays the values specified in the Zuora-Track-Id headers of the API requests

API Failures

All the failed API requests issued within the specified time range.

Besides the detailed information of the failed requests, you can also view the response code and response body of each of the failed request.

Note that some API failures might not be instantly picked up by the notification system because the notification system allows for a custom polling interval. It can cause a temporary discrepancy between the notification record and the API System Health dashboard. The impact of such a discrepancy should be minimal, and it will be auto-rectified over time.

API Performance

The response time data of the API requests within a specified time range. Available metrics include the following:

• P95: 95th percentile of the response time data
• P90: 90th percentile of the response time data
• P50: 50th percentile of the response time data

API Concurrency Limit

The concurrency limits data for the Default and High-volume transactions concurrency limit types within a specified time range.

• The trend charts in the API Concurrency Limit tab display the maximum concurrency data of the selected intervals. For example, when Day is selected as the interval, the chart displays the maximum number of concurrent requests each day within the specified time range.

• The minimum unit of the interval is minute, which means when setting the interval to Minute, the charts display the maximum concurrency per minute.

• See Concurrent request limit types for more information about request types. Note that the Object Query type is not supported by the System Health APIs dashboard.

• You can use the Concurrency Top API Insights table to view detailed information about the maximum concurrency of the selected time range. The following information is available:

  • API Description
  • HTTP Method
  • Tracing Identifier
  • Total Requests
  • Avg Execution Time
  • Total Execution Time
  • Concurrency Limit Type

Note that the Tracing Identifier column displays prefixes of the values specified in the Zuora-Track-Id headers of the API requests. For example, for any API requests triggered by the Workflow service, the prefix "WF" will be displayed as the tracing identifier. If Zuora-Track-Id is not specified in the request, the Tracing Identifier field will display "--".
