Exception event attributes
Example

When an operation throws an exception, a span must log the ERROR status and the exception event with the error details. Spans with the ERROR status are highlighted in the Monium Traces interface and can be filtered.

For information about the basic error handling pattern, see Statuses and errors. This page describes the exception event attributes based on the OpenTelemetry specification.

Exception event attributes

For example, in Python, calling record_exception creates an exception event with the following attributes:

Attribute	Description
`exception.type`	Exception type: `OSError`, `ValueError`, or `java.lang.RuntimeException`
`exception.message`	Error message: `Can't convert 'int' object to str implicitly`
`exception.stacktrace`	Exception stack trace

For a full list of attributes, see the OpenTelemetry specification for exception events.

Example

The parse_message operation fails with an error:

Attribute	Value
Name	`parse_message`
Kind	`INTERNAL`
Status	`ERROR`
`exception.type`	`ValueError`
`exception.message`	`Can't convert 'int' object to str implicitly`
`exception.stacktrace`	`Traceback (most recent call last): ...`
