Prometheus and Grafana integration concept in Spring Boot - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is Prometheus used for in monitoring?

Prometheus collects and stores metrics data from applications and systems to help monitor their performance and health.

beginner

What role does Grafana play when integrated with Prometheus?

Grafana visualizes the metrics data collected by Prometheus, creating easy-to-understand dashboards and graphs.

intermediate

How does a Spring Boot application expose metrics for Prometheus?

Spring Boot exposes metrics through an HTTP endpoint (usually /actuator/prometheus) that Prometheus scrapes to collect data.

intermediate

What is the purpose of the Prometheus scrape configuration?

It tells Prometheus where to find the metrics endpoints of applications, so it knows which URLs to collect data from and how often.

beginner

Why is it helpful to use both Prometheus and Grafana together?

Prometheus gathers raw metrics data, and Grafana turns that data into visual dashboards, making it easier to understand system health and spot issues.

Which endpoint does a Spring Boot app usually expose for Prometheus metrics?

A /actuator/prometheus

B /metrics/data

C /api/metrics

D /monitoring/stats

Spring Boot uses the /actuator/prometheus endpoint to expose metrics in a format Prometheus can scrape.

What does Prometheus do with the metrics it collects?

A Visualizes data in dashboards

B Sends alerts directly to users

C Stores them in a time-series database

D Deletes old logs

Prometheus stores metrics in a time-series database for later querying and analysis.

Grafana connects to Prometheus to:

A Send metrics to applications

B Visualize metrics data

C Collect metrics data

D Configure Prometheus scraping

Grafana is a visualization tool that creates dashboards from data stored in Prometheus.

In Prometheus configuration, what is a 'scrape job'?

A A data backup process

B A user alert notification

C A dashboard template

D A task to collect metrics from a target URL

A scrape job defines how and where Prometheus collects metrics data.

Why is it important to expose metrics in a standard format for Prometheus?

A So Prometheus can understand and collect the data correctly

B To improve application speed

C To secure the application

D To reduce memory usage

Prometheus expects metrics in a specific format to scrape and store them properly.

Explain how Prometheus and Grafana work together to monitor a Spring Boot application.

Think about data flow from app to visualization.

Describe the steps to configure Prometheus to monitor a Spring Boot app.

Focus on setup from app to Prometheus and then Grafana.
