Enum Class ErrorCategory

java.lang.Object
java.lang.Enum<ErrorCategory>
com.tnsai.observability.errors.ErrorCategory
All Implemented Interfaces:
Serializable, Comparable<ErrorCategory>, Constable
public enum ErrorCategory extends Enum<ErrorCategory>
Coarse classification of errors for routing, alerting, and budget tracking.

Each error reported via ErrorEmitter carries an ErrorCategory so dashboards can group "transient network blips" separately from "persistent auth failures" and operators can wire different alert/escalation policies per category.

Since:
0.5.0 (issue #86)

  • Enum Constant Summary

    Enum Constants
    Enum Constant
    Description
    CONFIG
    Misconfiguration — missing LLM, wrong model name, malformed role spec.
    EXTERNAL
    Third-party system failure — MCP server down, webhook 5xx, DB unavailable.
    INTERNAL
    Framework-internal bug — should not happen in production.
    LOGIC
    Assertion / invariant violation — internal logic bug, illegal state.
    PERMANENT
    Will not succeed on retry — bad credentials, invalid request, unsupported model.
    RESOURCE
    Exhausted resource — token budget, rate limit, capacity, disk full.
    SECURITY
    Blocked by policy — content filter, prompt injection detector, approval denied.
    TRANSIENT
    Will likely succeed on retry — network blip, overloaded model, transient 5xx.
    UNKNOWN
    Could not classify — defensive fallback.

  • Method Details

    • values

      public static ErrorCategory[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static ErrorCategory valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
