# 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

1. Multiple monitoring nodes across different network segments
2. Distributed database for sharing state
3. 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
