Interface names missing in CSV Export for “Chart per Metric” in NetOps portal

Products

Issue/Introduction

When generating an On-Demand Report in DX NetOps Portal with the chart type set to "Chart per Metric", the exported CSV file does not include the legend or the names of the selected interfaces/items.

While the legend is visible and correctly displayed in the PDF export, its absence in the CSV makes the report difficult to interpret or unusable, as the individual metric data lines cannot be correlated with specific interfaces or items.

Environment

DX NetOps Performance Management All releases

Cause

In the "Chart per Metric" option, data is aggregated for all selected items into a single chart. Due to an oversight or limitation in the CSV export logic, the system failed to include the corresponding interface names or a 'Selected Items List' in the CSV output format during this aggregation. 

Resolution

This issue has been resolved. With the applied fix, the CSV renderer for On-Demand Reports now correctly includes the 'Selected Items List' (e.g., interface names) when the 'Chart per Metric' option is selected. This ensures that CSV exports are fully usable and provide complete context for the data.

Additional Information

• This fix is implemented in DX NetOps Performance Management version 25.4.2.
