Bubble¶
Overview¶
A bubble can be used to show the relationship between three variables, similar to a scatter. It is divided into horizontal and vertical axes, with the inclusion of variables indicating magnitude for comparison.
It indicates the general trend of the dependent variable with the independent variable, from which the trend can be selected to fit the empirical distribution with a suitable function, and then find the functional relationship between the variables. It can be used to observe the distribution and aggregation of data. For example, you can view the distribution and aggregation of total CPU usage, CPU system usage and CPU user usage across hosts.
Operations¶
Chart Query¶
Please click chart query for detailed explanation of the chart query conditions, and add x-axis, y-axis and size queries by default. There is no Add Query button. Measurements and metrics of the query can be different, but the by (grouping) Tag must be the same, and if one is modified, the other two are automatically modified in parallel.
Chart Link¶
Links can help you jump from the current chart to the target page, you can add internal links and external links to the platform and modify the corresponding variable values in the links through template variables to transfer the data information to complete the data linkage. Please click chart link to view the related settings.
Chart Style¶
| Options | Description |
|---|---|
| Chart Title | It would be shown on the top left of the chart after setting the title name; it also supports hide. |
| Color | It refers to the display color of the chart data, enabling you to manually input custom preset color. The format is aggregation function (metric) {"label": "label value"}, such as last(usage_idle){"host": "guance_01"} |
| Alias | last(usage_idle){"host": "guance_01"}. |
Chart Setting¶
Basic Setting¶
| Options | Description |
|---|---|
| Unit | 1. You can set units for query results. 1）If the queried data has no unit, it will be displayed on the chart according to the set unit after setting the unit in the chart. 2）If the query data comes with its own units, or if you set the units for the metrics in Metric Management, the units set in the chart will be displayed on the chart. 3）If the query data has no units and no units are set in the chart, the chart Y-axis values are automatically calculated according to scientific notation; the original values are displayed on the chart in the format thousandths. Scientific counting instructions: Default query result value is automatically converted to units, display follows scientific notation K, M and B (1 thousand = 1K, 1 million = 1M, 1 billion = 1B), retaining two decimal points; RMB is automatically converted to units yuan, million, billion, retaining two decimal points. For example: The time interval of the unit is selected in ns, then according to the size of the data, the query results only automatically convert the unit effect as follows, and so on: 2. You can preset units for the query results and manually input format as: aggregation function (metric), such as last(age_idle) |
Advanced Setting¶
| Options | Description |
|---|---|
| Time slice | When time slicing is turned on, the original data will be aggregated in segments at certain time intervals, and then the aggregated data set will be aggregated a second time to get the result value, which is turned off by default. For details, please refer to time slicing description. |
| Lock time | Support locking the time range of chart query data, not limited by the global time component. The time set by the user will appear in the upper right corner of the chart after successful setup, e.g. 【xx minutes】, 【xx hours】, 【xx days】. If the time interval is locked at 30 minutes, then when adjusting the time component, no matter what time range view is queried, only the last 30 minutes of data will be displayed. |
| Time interval | If the time slice is off, there is no time interval option; if the time slice is on, the time interval option is as follows: |
| Field mapping | The object mapping function with view variables is off by default, if object mapping is configured in the view variables： |
| Chart Description | Add description information to the chart, after setting the chart title will appear behind the 【i】 prompt, do not set it will not be displayed |
| Workspace | A list of authorized workspaces, which can be queried and displayed via charts after selection |
Example¶
The following figure shows the distribution and aggregation of total CPU usage, CPU system usage and CPU user usage for different hosts for the last 15 minutes.
