Performance Analyzer API

    Performance Analyzer uses a single HTTP method and URI for most requests:

    For a full list of metrics, see Metrics reference. Performance Analyzer updates its data every five seconds. If you create a custom client, we recommend using that same interval for calls to the API.

    Performance Analyzer has one additional URI that returns the unit for each metric.
