    • Example: Use variables to switch between different data sources, time ranges, or filter options within a single Grafana dashboard.
  8. Data Exploration and Ad-hoc Queries:
    • Grafana provides the ability to explore and run ad-hoc queries on your data, facilitating on-the-fly analysis.
    • Example: Use Grafana’s Explore feature to execute ad-hoc queries on a Prometheus data source to investigate specific trends or anomalies.
  9. Histograms and Percentiles:
    • Grafana allows the creation of histograms and percentile charts for a deeper understanding of data distribution.
    • Example: Visualize response time percentiles to identify performance bottlenecks in an application.
  10. Gauge Panels for Key Metrics:
    • Grafana supports gauge panels, providing a clear visual representation of key metrics.
    • Example: Utilize gauge panels to display server CPU utilization or storage capacity on a single Grafana dashboard.
  11. Integration with Time Series Databases:
    • Grafana seamlessly integrates with time series databases such as InfluxDB, allowing users to store and visualize time-stamped data efficiently.
    • Example: Connect Grafana to InfluxDB to monitor and visualize sensor data in an industrial IoT environment.
  12. Sunburst Charts for Hierarchical Data:
    • Grafana supports Sunburst charts, enabling the visualization of hierarchical data structures.
    • Example: Represent organizational hierarchies or nested categories using Sunburst charts in Grafana.
  13. Prometheus Alertmanager Integration:
    • Grafana integrates with Prometheus Alertmanager, allowing users to manage and visualize alerts effectively.
    • Example: Set up Grafana to display the status and history of alerts triggered by Prometheus.
  14. Multi-data Source Dashboards:
    • Grafana enables the creation of dashboards with multiple data sources, allowing users to correlate data from different systems.
    • Example: Build a Grafana dashboard that combines metrics from Prometheus and logs from Elasticsearch to gain a holistic view of system performance.
  15. Custom Plugins and Panel Development:
    • Grafana’s extensibility allows users to develop custom plugins and panels tailored to specific requirements.
    • Example: Develop a custom Grafana panel to visualize data from a proprietary monitoring system or a specialized data source.
  16. Dynamic Table Panels:
    • Grafana supports dynamic table panels that enable the display of tabular data based on selected variables or queries.
    • Example: Create a dynamic table in Grafana to showcase detailed information about system resources, such as CPU usage and memory statistics.
  17. Custom Theming and Branding:
    • Grafana allows for custom theming and branding, enabling users to align dashboards with their organization’s visual identity.
    • Example: Customize the color scheme and logo in Grafana to match your company’s branding.
  18. Cost Monitoring and Analysis:
    • Grafana can be used for cost monitoring by integrating with cloud provider APIs and visualizing resource consumption.
    • Example: Connect Grafana to the AWS CloudWatch data source to visualize and analyze costs associated with different AWS services.
  19. Network Traffic Analysis:
    • Grafana is well-suited for visualizing network traffic patterns and analyzing data flows.
    • Example: Use Grafana to visualize network bandwidth usage, identify peak periods, and troubleshoot connectivity issues.
  20. Custom SQL Data Sources:
    • Grafana supports custom SQL data sources, allowing users to connect to relational databases and visualize SQL query results.
    • Example: Configure Grafana to connect to a PostgreSQL database and create dashboards based on custom SQL queries.
