GANDALF (Global Advanced Network Detection And Link Facilitator)
Because it shall not let problems pass!
Multiple Distributed Servers Approach
This architecture represents the most robust implementation approach for the system.
Core Components
- Multiple monitoring nodes across different network segments
- Distributed database for sharing state
- Consensus mechanism for alert verification
System Architecture
A. Monitoring Layer
- Multiple monitoring nodes in different locations/segments
- Each node runs independent health checks
- Mix of internal and external perspectives
B. Data Collection
Each node collects:
- Link status
- Latency measurements
- Error rates
- Bandwidth utilization
- Device health metrics
C. Consensus Mechanism
- Multiple nodes must agree before declaring an outage
- Voting system implementation:
- 2/3 node agreement required for issue confirmation
- Weighted checks based on type
- Time-based consensus requirements (X seconds persistence)
D. Alert Verification
- Cross-reference multiple data points
- Check from different network paths
- Verify both ends of connections
- Consider network topology
E. Redundancy
- Eliminates single points of failure
- Nodes distributed across availability zones
- Independent power and network paths
F. Central Coordination
- Distributed database for state sharing
- Leader election for coordinating responses
- Backup coordinators ready to take over
Additional Features
- Alarm suppression capabilities
- Ticket creation system integration
