UserProfile/users/:id/users/123http://example.com/users/123Span Description Documentation
This page contains documentation for known span descriptions. You can use this documentation to understand how to create the sentry.description attribute for a span, when you have the span's other attributes.
Generating Descriptions
Span descriptions are generated via string template. Each span category of work has a set of templates for the span description. Curly brackets in the template indicate that the contents inside the curly brackets should be replaced with the contents of the span attribute of the name within the brackets.
The templates should be evaluated in order of appearance. Every template references at least one attribute.
Example
Given template:
{{db.query.text}}
And attribute db.query.text = "SELECT * FROM users WHERE id = ?":
Result: "SELECT * FROM users WHERE id = ?"
