Grafana PerfCurve 插件

概览

PerfCurve 是一个 Grafana 面板插件，用于在画布上绘制旋转机械（如泵、压缩机等）的操作点及其性能曲线。您只需提供性能曲线上的采样点，即可在画布上绘制多条性能曲线。该面板插件可平滑连接采样点。

重要提示！！

请根据以下规则选择插件版本。

• 对于 Grafana >= 8.X.X，请使用版本 >= 1.5.X
• 对于 Grafana >= 7.4.X，请使用版本 >= 1.4.X
• 对于 Grafana <= 7.3.X，请使用版本 <= 1.3.X

入门

轴

指定 X 轴和 Y 轴的最小值、最大值、标签、单位和小数位数。

静态曲线

通过以逗号分隔值格式指定采样点，将性能曲线添加到画布。
X 输入框和 Y 输入框中的值数量必须相同。基于采样点绘制自然曲线。

动态曲线 (高级)

如果数据库中存在性能曲线数据，可以使用这些数据绘制基于数据动态移动的性能曲线。（查询示例是针对 InfluxDB 数据源编写的。）

操作点

设置 X 框和 Y 框的字段名称以绘制操作点。同时设置标签、颜色和点半径。
建议将表格格式作为查询选项。

TestData DB 示例

请参阅随附的 TestData DB 示例输入。如果您将 TestData DB 添加到数据源，则 TestData DB 默认可用。
