問題文
The finance department asks whether the store's Prometheus data can be used to bill merchants for the exact number of API calls they made last month. What should the team tell them, according to the project's own guidance?
選択肢
- The data is not suitable, because the collected samples are unlikely to be detailed and complete enough when total accuracy is required.
- The data is suitable because counters never lose increments, so the difference between two scraped samples is always the exact number of calls.
- The data is suitable as long as the scrape interval is lowered to one second, which removes the gaps that would otherwise cause undercounting.
- The data is suitable if remote write is enabled, because the remote endpoint receives every individual request as its own sample.
