Charts

Kube AI Hub currently supports two kinds of charts: text charts and graphs.

Text Chart

A text chart is preferable for displaying a single metric value. The editing window for the text chart is composed of two parts. The upper part displays the real-time metric value, and the lower part is for editing. You can enter a PromQL expression to fetch a single metric value.

• Chart Name: The name of the text chart.
• Unit: The metric data unit.
• Decimal Places: Accept an integer.
• Monitoring Metric: Specify a monitoring metric from the drop-down list of available Prometheus metrics.

Graph Chart

A graph chart is preferable for displaying multiple metric values. The editing window for the graph is composed of three parts. The upper part displays real-time metric values. The left part is for setting the graph theme. The right part is for editing metrics and chart descriptions.

• Chart Types: Support basic charts and bar charts.
• Graph Types: Support basic charts and stacked charts.
• Chart Colors: Change line colors.
• Chart Name: The name of the chart.
• Description: The chart description.
• Add: Add a new query editor.
• Metric Name: Legend for the line. It supports variables. For example, {{pod}} means using the value of the Prometheus metric label pod to name this line.
• Interval: The step value between two data points.
• Monitoring Metric: A list of available Prometheus metrics.
• Unit: The metric data unit.
• Decimal Places: Accept an integer.
