DevOps Complete Course - Grafana Setup

The video tutorial covers configuring Grafana, adding data sources like Prometheus, and modifying Helm charts and YAML files for deployment. It explains the importance of persistent volume claims (PVCs) for data storage and demonstrates the installation and access of Grafana dashboards. The tutorial also shows how to create and import dashboards, highlighting the flexibility of Grafana in visualizing data from various sources.

What is the primary role of Prometheus in the context of Grafana?

• To act as a database management system

• To serve as a web server

• To collect and store metrics data

• To provide a user interface for data visualization

Which file is modified to customize the deployment settings of Grafana using Helm?

• config.yaml

• deployment.yaml

• values.yaml

• settings.yaml

Which command is used to view the values.yaml file from a Helm chart?

• helm show values

• helm get values

• helm view values

• helm inspect values

Why is it important to use persistent volume claims (PVC) in Grafana?

• To ensure data persistence across pod restarts

• To enhance the graphical interface

• To increase the speed of data retrieval

• To improve network security

What happens if a Grafana pod is restarted without a PVC?

• The pod becomes read-only

• The data remains intact

• The data is erased

• The pod fails to restart

What is the default behavior of Grafana if persistent volume claims are not enabled?

• Data is encrypted and stored securely

• Data is backed up automatically

• Data is stored locally and lost on pod deletion

• Data is stored in a cloud database

What is the purpose of configuring a node port in Grafana?

• To enable internal communication within the cluster

• To allow access to Grafana through a web browser

• To increase the security of the Grafana dashboard

• To connect Grafana to a database

Which of the following is a correct step to access Grafana through a browser?

• Configure a load balancer

• Set the service type to NodePort

• Use a VPN connection

• Install a browser plugin

Which of the following is NOT a data source option in Grafana?

• MySQL

• Prometheus

• Elasticsearch

• Microsoft Word

How can you import a new dashboard theme in Grafana?

• By uploading a theme file

• By entering a dashboard ID

• By modifying the values.yaml file

• By changing the node port settings
