Condition Persistence and Repeated Re-Check for Diagnosis Alerts

NetBrain currently triggers an alert as soon as a diagnostic condition is met, without a way to confirm that the condition persists over time or to re-check it at defined intervals. This can result in alerts being generated from brief, transient spikes rather than sustained issues. This enhancement would introduce a configurable option to require a condition to persist for a defined duration before an alert is triggered, along with an option to automatically re-evaluate the diagnosis at set intervals. Supporting persistence and interval-based re-checking would reduce false-positive alerts and help ensure that notifications reflect genuine, sustained performance issues.
