Pull Request Overview
This PR fixes NaN (Not a Number) values appearing in CPU and RAM metrics for external resources by adding zero-value checks before performing division operations. The fix prevents division by zero scenarios that were causing the NaN values to appear in the UI.
Key changes:
- Added a null/zero check in the
calculateResourceAllocatedPercentagemethod to return "0.00%" when either the resource or resourceWithOverProvision values are zero - Refactored existing inline percentage calculation to use the centralized
calculateResourceAllocatedPercentagemethod for consistency
| return "0.00%"; | ||
| } | ||
| DecimalFormat decimalFormat = new DecimalFormat("#.##"); | ||
| return decimalFormat.format(((float)resource / resourceWithOverProvision * 100.0f)) + "%"; |

The cast to (float) is unnecessary since the parameters are already declared as float. This redundant cast reduces code readability.
| return decimalFormat.format(((float)resource / resourceWithOverProvision * 100.0f)) + "%"; | |
| return decimalFormat.format((resource / resourceWithOverProvision * 100.0f)) + "%"; |

@sureshanaparti I don't think Copilot's comment are completely relevant. I've added my comments in their reply |
