Frequently Asked Questions

What are the advantages of using Grafana and Prometheus together?

Using Grafana and Prometheus together provides a powerful monitoring solution. Prometheus collects data, while Grafana lets you visualize it in clear and customizable dashboards. It also allows you to set alarms, detect anomalies, and perform in-depth analysis of system performance.

What metrics might Prometheus collect?

Prometheus can collect system resources such as CPU usage, memory consumption, disk I/O, and network traffic, as well as application-specific metrics (e.g., number of requests, response times, error rates). Essentially, it can collect any numerical data exported by the target system.

How can Grafana dashboards be customized?

Grafana dashboards can be customized with various panels to visualize data from different data sources (Prometheus, Graphite, InfluxDB, etc.). Many different visualization options are available, including line charts, bar charts, heatmaps, and single-value panels. Additionally, different dashboards can be created for different users and filtered for specific time periods.

How can I configure Prometheus so it only collects certain metrics?

In the Prometheus configuration file (prometheus.yml), in the `scrape_configs` section, you can specify the target systems and the metrics to collect. By using tags and matching rules, you can configure Prometheus to collect only the metrics you need. This reduces resource consumption and results in a cleaner database.

How to create and manage alerts in Grafana?

To create alerts in Grafana, you define threshold values for a specific metric on a dashboard. When these values are exceeded, a notification is sent via a predefined channel (e.g., email, Slack, PagerDuty). Regularly reviewing alert rules and disabling unnecessary alerts helps you manage your system more efficiently.
