Most monitoring tools are built to detect failures that produce errors.
But in real systems, the bigger issue is often what doesn’t happen.
No new signups for hours
No payments coming in
Background jobs stuck silently
AI agents looping without completing tasks
Everything looks healthy — servers are up, logs are clean, dashboards are green — yet the business itself is not moving.
These issues usually go unnoticed because there are no errors to trigger alerts.
NotiLens focuses on this gap by monitoring real business signals and alerting when expected activity drops or stops, helping teams detect issues that traditional monitoring tools miss.
Would love to hear how others currently track “missing activity” or silent failures in their systems.
