Monitoring and Observability are the heart of a stable production environment. This quiz will test your knowledge on how metrics are collected, how to query them using PromQL, and how to build meaningful visualizations in Grafana. Let’s see how much you know about keeping your systems visible! Answer key and explanations20 questions The quiz above draws 20 questions at random from these 30, so a second attempt will not be the same run. Everything in the pool is listed here. 1. What is the primary data model used by Prometheus? AnswerTime-series data identified by metric names 2. What does it mean that Prometheus is a "Pull-based" system? AnswerPrometheus initiates HTTP requests to scrape metrics 3. What is a Prometheus "Exporter"? AnswerA proxy that translates service metrics into Prometheus format 4. Which metric type is used for a value that only goes up (like a request counter)? AnswerCounter 5. What is "PromQL"? AnswerThe functional query language used to process metrics 6. What is the "Node Exporter" used for? AnswerCollecting hardware-level metrics from the host OS 7. What is a "Gauge" metric used for? AnswerMeasuring a value that can increase or decrease over time 8. In Grafana, what is a "Data Source"? AnswerThe underlying database that stores the observability data 9. What is the purpose of the "Alertmanager"? AnswerRouting, grouping, and deduplicating alert notifications 10. What does the PromQL query "rate(http\_requests\_total\[5m\])" calculate? AnswerThe average per-second growth rate over a 5-minute window 11. In Grafana, what is a "Variable" (Dashboard Variable)? AnswerA dynamic placeholder used to filter data across panels 12. What is "Cardinality" in Prometheus? AnswerThe total number of unique time-series in the system 13. What does the "Job" label usually represent in Prometheus? AnswerA group of targets serving the same technical purpose 14. What is the "Scrape Interval"? AnswerThe frequency at which Prometheus collects data from targets 15. What is the purpose of "Labels" in Prometheus? AnswerTo enable multi-dimensional filtering and data aggregation 16. What is "Prometheus Federation"? AnswerA method for scaling by having one server scrape another 17. What is a "Histogram" in Prometheus? AnswerA metric that tracks the distribution of values across buckets 18. In Grafana, what does a "Panel" represent? AnswerA single visualization block (graph, gauge, or table) 19. What is the "Pushgateway" used for? AnswerAllowing short-lived batch jobs to expose metrics to Prometheus 20. What is "Alert Grouping" in Alertmanager? AnswerConsolidating multiple related alerts into a single notification 21. What is "Silence" in Alertmanager? AnswerA mechanism to mute notifications for a defined period of time 22. What is a "Service Discovery" in Prometheus? AnswerThe automated identification of new scrape targets via APIs 23. What does the "sum" operator do in PromQL? AnswerAggregates multiple time-series into a single total value 24. What is "Retention Time" in Prometheus? AnswerThe duration for which Prometheus stores metrics before deletion 25. What is "Grafana Loki"? AnswerA log aggregation system that uses Prometheus-style labels 26. What is "Prometheus Recording Rules"? AnswerA method to pre-calculate and save complex queries as metrics 27. In Grafana, what is "Provisioning"? AnswerUsing configuration files to define dashboards and sources 28. What is "Blackbox Exporter"? AnswerA probe that monitors endpoints via HTTP, DNS, or ICMP 29. What is "Inhibitions" in Alertmanager? AnswerMuting specific alerts if a related parent alert is already active 30. What is "Reporting" in Grafana? AnswerA feature that generates and emails PDF snapshots of dashboards ## Tags [#Prometheus](/quizzes/tags/prometheus)[#Grafana](/quizzes/tags/grafana)[#PromQL](/quizzes/tags/promql)[#Metrics](/quizzes/tags/metrics)[#Alerting](/quizzes/tags/alerting) ## Share [Facebook](https://facebook.com/sharer/sharer.php?u=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fprometheus-grafana-monitoring-quiz "Share on Facebook")[Twitter](https://twitter.com/intent/tweet/?text=Prometheus%20%26%20Grafana%3A%20Monitoring%20%26%20Observability%20Fundamentals&url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fprometheus-grafana-monitoring-quiz "Share on Twitter")[LinkedIn](https://www.linkedin.com/shareArticle?mini=true&url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fprometheus-grafana-monitoring-quiz&title=Prometheus%20%26%20Grafana%3A%20Monitoring%20%26%20Observability%20Fundamentals&summary=Test%20your%20monitoring%20and%20observability%20skills%20with%20this%20quiz%20on%20Prometheus%20metrics%2C%20PromQL%2C%20Grafana%20dashboards%2C%20and%20alerting%20logic.&source=https://mkabumattar.com "Share on LinkedIn")[WhatsApp](https://wa.me/?text=Prometheus%20%26%20Grafana%3A%20Monitoring%20%26%20Observability%20Fundamentals%20https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fprometheus-grafana-monitoring-quiz "Share on WhatsApp")[Telegram](https://t.me/share/url?url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fprometheus-grafana-monitoring-quiz&text=Prometheus%20%26%20Grafana%3A%20Monitoring%20%26%20Observability%20Fundamentals "Share on Telegram")[Reddit](https://www.reddit.com/submit?url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fprometheus-grafana-monitoring-quiz&title=Prometheus%20%26%20Grafana%3A%20Monitoring%20%26%20Observability%20Fundamentals "Share on Reddit")[Hacker News](http://news.ycombinator.com/submitlink?u=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fprometheus-grafana-monitoring-quiz&t=Prometheus%20%26%20Grafana%3A%20Monitoring%20%26%20Observability%20Fundamentals "Share on Hacker News")[Pinterest](https://pinterest.com/pin/create/button/?url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fprometheus-grafana-monitoring-quiz&media=&description=Test%20your%20monitoring%20and%20observability%20skills%20with%20this%20quiz%20on%20Prometheus%20metrics%2C%20PromQL%2C%20Grafana%20dashboards%2C%20and%20alerting%20logic.
