Logs and Metrics

FunctionGraph graphically displays function monitoring metrics and collects function running logs, enabling you to view function statuses, and locate problems by querying logs.

For details on how to query logs, see Querying Logs.

For details on how to view function metrics, see Viewing Function Metrics.

For details about tenant-level monitoring information, see Dashboard.

Function Initialization

The initializer interface is introduced to:

  • Isolate function initialization and request processing to enable clearer program logic and better structured and higher-performance code.
  • Ensure smooth function upgrade to prevent performance loss during the application layer's cold start initialization. Enable new function instances to automatically execute initialization logic before processing requests.
  • Identify the overhead of application layer initialization, and accurately determine the time for resource scaling and the quantity of required resources. This feature makes request latency more stable when the application load increases and more function instances are required.
