Accurate NCT Table Refresh Behavior When Latest Poll Returns No Data

NetBrain currently does not update or clear NCT table data when the most recent polling attempt returns no results, such as after configuration changes remove previously monitored items. Instead, the table continues to display the last successful data pull, and the product does not differentiate between a successful empty result, a failed retrieval, and an unreachable device, which can cause the displayed baseline to appear inaccurate. This enhancement would ensure the NCT table reflects the actual outcome of the most recent poll, showing an empty result when appropriate and clearly indicating polling or connectivity failures separately from valid empty data. This would allow customers to rely on the table's current baseline for automation and reporting without needing to manually verify data accuracy through alternative methods.
