Why do collectors communicate with the Supervisor after registration?

Afterregistration, collectors maintaincontinuous communicationwith theSupervisorto ensure properevent processing, system health monitoring, and failover handling. The two key reasons collectors communicate with the Supervisor are:

1.To upload event data if a worker is down

If aworker node fails, thecollector can temporarily store event logsand then forward them to the Supervisor.

This ensuresevent continuityeven during infrastructure issues.

2.To report its own health status

Thecollector sends health reportsto theSupervisor, including resource usage, connectivity status, and operational logs.

This helps FortiSIEM trackcollector uptime and performance.
