Customizing Explorer charts

By default, Explorer reports display as bar charts within the cluster management console. You can also create custom charts to show the same data as a pie, area, line, or table chart. Currently, IBM® Spectrum Symphony provides one Explorer report: the Charge Back chart. This topic describes how to customize the Charge Back chart to show the data in pie chart format.

1. From the cluster management console, select Reports & Logs > Explorer Reports > Charts.
2. Provide a name for your custom chart.

   For example, to create a pie chart, call your custom chart My Charge Back Pie Chart.

3. From the Data Source list, select a data source for your chart.

   Data sources are automatically created at installation by the installer, and are defined in the $EGO_CONFDIR/../../explorer/config/config.json file.

4. From the Index list, select an Elasticsearch database index name for your chart.

   Currently, the data source contains only one index: ibm-symphony-report-charge-back, which stores aggregated charge back data for the Charge Back chart.

5. Select the dimensions for your chart.

   Create a chart showing charge back values by resource group and by consumer, by selecting resource_group and consumer_name.

6. Provide a label for each dimension by modifying the Name in the chart values for each dimension, and selecting Add for each.

   For example, specify Resource Group and Consumer Name for the Name in the chart values, and select Add for each.

7. Specify charge back rate calculation options by selecting a measurement and an aggregation option, and provide a label for the measurement by modifying the Name in the chart value, and selecting Add.

   For example, select the chargeback_value measure, and the Sum aggregation options to calculate the value of the charge back rate for the chart. Specify Total Charge Back Value for the Name in the chart value, and select Add.

8. Specify how filtering options for the chart will display by specifying selection types and filter display names from the Filters section.
   For example:

   • To show a filter by cluster name in the chart, select cluster_name with Multiple Selection as the selection type, and specify Cluster Name as the display name.
   • To show a filter by date and time range, select event_time with Single Selection as the selection type, specify Date and Time Range as the display name, and select Relative Time of past 7 days.
9. Click Next to see a preview of your custom chart.
10. Select a chart type (Pie, Bar, Area, Line, or Table) to best display your data.

    For example, select Pie to show the data as a pie chart.

    Examine the preview to ensure that it meets your requirements; return to the previous screen to make any modifications.

11. When you are satisfied with your new custom chart, select a category where your chart will be stored.
12. Click Save.
