Capturing and analyzing distributed traces

Objective 4.4 sits in Implementing observability practices and troubleshooting issues, which carries 25% of the Cloud DevOps Engineer exam. The questions below are original, written from the official objective title above, and each explanation cites the Google Cloud page it rests on.

4-4Implementing observability practices and troubleshooting issues

An engineer opens the latency graph and finds it aggregating something narrower than a whole request. What is being aggregated?

Traces, each covering one whole operationThe whole operation is the coarser unit and is not what the graph breaks down.
Log entries emitted during the requestLog entries live in a different product and never appear on this latency chart.
Spans, which describe trace sub-operationsCorrect · your answerCorrect: the finer unit is what the graph plots.
Uptime check results from the same regionProbe results are a separate signal and are not part of a request breakdown.

Correct.

Concept

A single operation and the steps inside it are different units of measurement. Aggregating at the finer unit is what lets one slow dependency stand out from the request that contains it.

Why C

The whole operation is one unit and each sub-operation inside it is another. Latency is charted at the finer level, so selecting one of them opens the detail for the operation it belongs to.

Source

The graph displays aggregated latency data for spans , which describe trace sub-operations.
