    Function metrics

    Function metrics in Ontology Manager display the near real-time usage of a function type. The following metrics are available from a function type's overview page:

    • Success/failure metrics: Monitor the current status of your functions with success and failure counts. This enables rapid identification of issues and supports proactive troubleshooting, allowing you to address failures as soon as they occur.
    • P95 duration metric: Track the 95th percentile (P95) execution duration for each function type. This metric highlights the upper range of execution times, helping you detect performance bottlenecks and optimize workflows for consistent and efficient operation.

    You are also able to access run history, which provides a complete view of a given function's executions over the past seven days. Learn more about AIP Observability.

    All metrics are updated in near real-time using the latest data from the Foundry Telemetry Service (FTS). This ensures you have access to the most current information for monitoring, debugging, and maintaining the health of your functions.

    Function metrics have a variety of categories of failures that may be displayed. These categories are:

    • Runtime failure: An unexpected error occurred while executing the function, often due to a bug or unhandled situation in the function's code.
    • Resource limit exceeded: The function affected more than the permitted limit of object types (by default, usually 10,000).
    • User facing error: An error occurred that is specifically intended to be shown to the user, often providing guidance on what went wrong or how to fix it.
    • Invalid inputs error: One or more of the inputs provided to the function were not valid or did not meet the required criteria.
    • Invalid output error: The function produced output that was not valid or did not conform to the expected format or rules.
    • Data loading not allowed error: The function execution attempts to load data, including objects, object sets, users, or groups, but is not allowed to do so.
    • Undeclared object types edited error: The function execution attempts to update, create or delete an object whose object type is not declared in the function spec.
    • Structured error: The function execution encounters a structured error as defined on its spec.
    • Deployment error: The function execution failed due to an error with the function's deployment.
    • Consistent snapshot error: The function failed to execute due to a consistent snapshot error.
