Once an API is published and is being consumed at runtime, metrics information about that usage is recorded in OpenSearch. For each request, various pieces of information is stored, including but not necessarily limited to the following:

  • Request start and end times
  • API start and end times
  • Resource path
  • Response type (success, failure, error)
  • API info (org id, id, version)
  • Client App info (org id, id, version)

You can access these metrics through the API Management UI, or you can analyze the data using the Log Analyzer. API Management provides some basic, predefined metrics, the Log Analyzer is a reporting tool that lets you define your own reports on base of the OpenSearch data.

Metrics in the API Management UI

In API Management, some basic metrics based on API data and based on client data are available through the UI.

API Metrics

This tab is only visible for published APIs.

Metric Reports Using the Log Analyzer

The log analyzer is an analytics and visualization tool designed to work with OpenSearch. With the log analyzer you can search, view, and interact with data stored in OpenSearch indices. You can perform advanced data analysis and visualize your data in a variety of charts, tables, and maps.

The Scheer PAS Log Analyzer already contains some default dashboards for API Management users. For more information about the log analyzer, refer to the Administration Guide > Analyzing Platform Logs.

The log analyzer is based on OpenSearch, for detailed information, refer to the Official OpenSearch Documentation.
