How Distributed Monitoring Works

1

Create Your Monitor

Add any HTTP/HTTPS endpoint. Set check intervals from 1 to 10 minutes.

2

Agents Take Action

3 agents from different locations check your endpoint simultaneously.

3

Consensus Verification

Results are verified through consensus. No false positives from single-point failures.
