Knowledge Base & Operational DocumentationWhat to Do When Security Monitoring Stops Receiving Endpoint Alerts
A quiet security console can mean fewer incidents, but it can also indicate that agents, connectors, certificates, or ingestion pipelines stopped sending data. Loss of telemetry should be treated as a visibility gap until verified.
What to check
Check source health dashboards, last-seen times, agent service state, update status, network connectivity, certificate validity, ingestion quotas, and recent policy changes. Compare expected device inventory with reporting endpoints.
Recommended next step
Restore telemetry from a small representative endpoint group and confirm events reach the correct workspace with accurate timestamps. Escalate devices that remain silent and alert on future source-health failures.
