Overview

A span represents a single operation within a trace. Spans can be nested to form a trace tree. Often, a trace contains a root span that describes the end-to-end latency, and one or more subspans for its sub-operations. A trace can also contain multiple root spans, or none at all. Spans do not need to be contiguous—there may be gaps or overlaps between spans in a trace.

#display_name ⇒ Google::Devtools::Cloudtrace::V2::TruncatableString

Returns A description of the span's operation (up to 128 bytes). Stackdriver Trace displays the description in the Google Cloud Platform Console. For example, the display name can be a qualified method name or a file name and a line number where the operation is called. A best practice is to use the same display name within an application and at the same call point. This makes it easier to correlate spans in different traces.

For example, the display name can be a qualified method name or a file name and a line number where the operation is called.
