Why are provider billing reports an inadequate substitute for monitoring managed cloud services?
Select an answer to reveal the explanation.
Short Explanation
Billing data is aggregated and delayed, so it tells you what you used, not what's happening now. You need operational telemetry to see latency, error rates, and throughput as they happen.
Full Explanation
The correct answer is the statement that billing data is aggregated and delayed and describes cost rather than behaviour, so it cannot show latency, error rates or throughput as they happen. Billing records exist to account for consumption. They arrive well after the fact and are aggregated to a granularity that hides the per-request behaviour operations teams need.
The claim that billing reports are not available for managed services is incorrect because billing reports certainly exist for managed services; they are simply the wrong instrument.
The claim that Instana cannot read billing data under any circumstances is incorrect because the objection is relevance rather than technical access.
The claim that billing reports are accurate but are updated too frequently to be useful operationally is incorrect because it inverts the actual problem; billing data is too infrequent and too coarse, not too frequent.
For the exam, distinguish cost telemetry from operational telemetry and match each to the question it answers.
