- Table: Tables are used to present tabular data in a structured format. They are customizable and can be sorted, filtered, and styled to suit specific needs. Tables are useful for displaying large sets of data or comparing multiple metrics.
- Heatmap: Heatmaps are a way to represent data using colors to visualize the density of a data set. They are well-suited for visualizing data that has two axes, such as time and value, and allow users to quickly identify patterns or anomalies.
- Gauge: Gauge panels display a single value within a predefined range, represented as a circular gauge. They are often used to represent metrics like CPU usage, memory usage, or disk space.
- Bar Gauge: Bar gauges are similar to gauges but represent the value as a vertical bar instead of a circular gauge. They are useful for displaying percentages or values within a specified range.
- Pie Chart: Pie charts are circular charts divided into slices, with each slice representing a different category or data series. They are useful for visualizing data distributions or proportions.
- Alert List: Alert lists provide a summary of triggered alerts, displaying relevant information such as the alert name, severity, and time of occurrence. Users can click on the alerts to get more details or take appropriate actions.
These are just a few of the visualization options available in Grafana on Google Cloud. Users can further enhance their visualizations by applying customizations, such as annotations, thresholds, and metrics transformations, to create meaningful and interactive dashboards.
