# Semantic conventions for messaging exceptions

LLMS index: [llms.txt](/llms.txt)

**Status**: [Development][DocumentStatus]

This document defines semantic conventions for recording exceptions on messaging operations.


## Messaging create exception

<!-- semconv event.messaging.create.exception -->
<!-- NOTE: THIS TEXT IS AUTOGENERATED. DO NOT EDIT BY HAND. -->
<!-- see templates/registry/markdown/snippet.md.j2 -->
<!-- prettier-ignore-start -->

**Status:** ![Development](https://img.shields.io/badge/-development-blue)

The event name MUST be `messaging.create.exception`.

This event represents an exception that occurred during a messaging create operation.

This event SHOULD be recorded when an exception occurs during a messaging create operation.
Instrumentations SHOULD set the severity to WARN (severity number 13) when recording this event.
Instrumentations MAY provide a configuration option to populate exception events with the attributes captured on the corresponding messaging create span.

**Attributes:**

| Key | Stability | [Requirement Level](/docs/specs/semconv/general/attribute-requirement-level/) | Value Type | Description | Example Values |
| --- | --- | --- | --- | --- | --- |
| [`exception.message`](/docs/specs/semconv/registry/attributes/exception.md) | ![Stable](https://img.shields.io/badge/-stable-lightgreen) | `Conditionally Required` [1] | string | The exception message. [2] | `Division by zero`; `Can't convert 'int' object to str implicitly` |
| [`exception.type`](/docs/specs/semconv/registry/attributes/exception.md) | ![Stable](https://img.shields.io/badge/-stable-lightgreen) | `Conditionally Required` [3] | string | The type of the exception (its fully-qualified class name, if applicable). The dynamic type of the exception should be preferred over the static type in languages that support it. [4] | `java.net.ConnectException`; `OSError` |
| [`exception.stacktrace`](/docs/specs/semconv/registry/attributes/exception.md) | ![Stable](https://img.shields.io/badge/-stable-lightgreen) | `Recommended` | string | A stacktrace as a string in the natural representation for the language runtime. The representation is to be determined and documented by each language SIG. | `Exception in thread "main" java.lang.RuntimeException: Test exception\n at com.example.GenerateTrace.methodB(GenerateTrace.java:13)\n at com.example.GenerateTrace.methodA(GenerateTrace.java:9)\n at com.example.GenerateTrace.main(GenerateTrace.java:5)` |

**[1] `exception.message`:** Required if `exception.type` is not set, recommended otherwise.

**[2] `exception.message`:**

> [!WARNING]
>
> This attribute may contain sensitive information.

**[3] `exception.type`:** Required if `exception.message` is not set, recommended otherwise.

**[4] `exception.type`:** If the recorded exception type is a wrapper that is not meaningful for
failure classification, instrumentation MAY use the type of the inner
exception instead. For example, in Go, errors created with `fmt.Errorf`
using `%w` MAY be unwrapped when the wrapper type does not help
classify the failure.
