## Issues Identified

### Critical Issues

1. **VMID 2401, 2402**: 
   - ❌ Services not running
   - ❌ `p2p-host` set to `0.0.0.0` (should be specific IP: 192.168.11.241, 192.168.11.242)
   - ❌ Missing static-nodes.json
   - ❌ Missing permissions-nodes.toml
   - ❌ No ports listening

2. **VMID 2503, 2504**: 
   - ❌ Containers stopped
   - ❌ No service status available

3. **VMID 2505-2508**: 
   - ❌ Services not running
   - ❌ No ports listening
   - ❌ Missing configuration files (config not found in standard locations)
   - ❌ Missing static-nodes.json
   - ❌ Missing permissions-nodes.toml

### Configuration Issues

1. **VMID 2500**: 
   - ⚠️ Network ID is 138 (expected 2400 for TCG Verse Mainnet)
   - ✅ Service is active and running
   - ✅ Config file at `/etc/besu/config-rpc.toml`

2. **VMID 2501, 2502**: 
   - ⚠️ Config files exist but network-id not readable (may need permissions check)
   - ✅ Services are active and running

3. **VMID 2505-2508**: 
   - ❌ Configuration files not found
   - ❌ Services not installed or configured

2. **VMID 2401, 2402**: 
   - ⚠️ `p2p-host` incorrectly set to `0.0.0.0` instead of specific IP addresses

3. **Static Nodes**: 
   - ⚠️ Most RPC nodes missing `static-nodes.json` (only 2400 and 2500 have it)

4. **Permissions**: 
   - ⚠️ Several RPC nodes (2401, 2402, 2503-2508) missing `permissions-nodes.toml`

### Service Issues

1. **VMID 2400**: 
   - ⚠️ Systemd service shows "inactive" but Besu process is running
   - ✅ Ports are listening and nodes are syncing
   - **Action**: Verify systemd service name or check if started manually

2. **VMID 2500-2502**: 
   - ✅ Services are active and running correctly
   - ✅ Ports are listening and nodes are syncing

2. **VMID 2401, 2402, 2505-2508**: 
   - ❌ Services not running
   - ❌ No Besu processes active

### Connectivity Issues

1. **VMID 2500**: 
   - ⚠️ Error in logs: `ArrayIndexOutOfBoundsException` for `eth_feeHistory` method
   - ✅ Still syncing and has 5 peers

2. **VMID 2400**: 
   - ⚠️ Only 2 peers (validators have 11-12 peers)
   - ✅ Still syncing blocks

### RPC Endpoint Issues

1. **VMID 2400, 2500-2502**: 
   - ⚠️ RPC endpoints returning HTML instead of JSON (may be behind reverse proxy)
   - ✅ Ports 8545 are listening

---

## Recommendations

### Immediate Actions Required

1. **Fix VMID 2401, 2402**:
   - Update `p2p-host` in config to specific IPs (192.168.11.241, 192.168.11.242)
   - Copy static-nodes.json from VMID 2400
   - Copy permissions-nodes.toml from VMID 2400
   - Start besu-rpc service

2. **Start VMID 2503, 2504**:
   - Start containers: `pct start 2503` and `pct start 2504`
   - Verify service status after startup

3. **Fix VMID 2500**:
   - ⚠️ **CRITICAL**: Network ID is 138 but should be 2400 for TCG Verse
   - Update network-id in `/etc/besu/config-rpc.toml` to 2400
   - Restart service after change

4. **Fix VMID 2501, 2502**:
   - Verify network ID in config files
   - Check file permissions if network-id not readable
   - Ensure network ID is 2400 for TCG Verse

5. **Fix VMID 2505-2508**:
   - Install Besu if not installed
   - Create configuration files
   - Verify network ID is 2400
   - Copy static-nodes.json and permissions-nodes.toml
   - Create and start besu-rpc services

### Configuration Improvements

1. **Standardize Configuration**:
   - Ensure all RPC nodes have config files in `/etc/besu/`
   - Verify all nodes have correct `p2p-host` (specific IP, not 0.0.0.0)
   - Ensure all nodes have static-nodes.json and permissions-nodes.toml

2. **Service Management**:
   - Verify systemd service names for VMID 2400, 2500-2502
   - Ensure all services are enabled: `systemctl enable besu-rpc`
   - Standardize service startup across all nodes

3. **Network Configuration**:
   - Verify all nodes have correct network IDs (138 for Defi Oracle, 2400 for TCG Verse)
   - Ensure P2P hosts match container IP addresses

### Monitoring

1. **Peer Connectivity**:
   - Monitor peer counts (validators have 11-12, RPC nodes should have similar)
   - VMID 2400 has only 2 peers - investigate connectivity

2. **Block Sync**:
   - All active nodes appear to be syncing (block heights consistent)
   - Monitor sync status regularly

3. **RPC Endpoints**:
   - Verify RPC endpoints return JSON (not HTML)
   - Test all RPC methods for functionality

### Maintenance

1. **Regular Checks**:
   - Weekly service status review
   - Monthly configuration audit
   - Quarterly peer connectivity analysis

2. **Documentation**:
   - Document configuration file locations for VMID 2500-2508
   - Document any non-standard service names
   - Maintain inventory of static nodes and permissions

- **Validators**: 5 (1000-1004) - ✅ **ALL OPERATIONAL**
- **RPC Nodes**: 13 (2400-2402, 2500-2508)

### Operational Status

**✅ Fully Operational**: 8 nodes
- Validators: 5 (1000-1004)
- RPC Nodes: 3 (2400, 2500-2502)

**⚠️ Configuration Issues**: 1 node
- VMID 2500: Network ID is 138 (expected 2400 for TCG Verse chain)

**❌ Not Operational**: 8 nodes
- VMID 2401, 2402: Services not running, configuration issues
- VMID 2503, 2504: Containers stopped
- VMID 2505-2508: Services not running, missing configuration

### Key Findings

1. **Validators**: All 5 validators are healthy with 11-12 peers each
2. **Chain 138 RPC**: Only 1 of 3 nodes operational (2400)
3. **Chain 2400 RPC**: Only 3 of 9 nodes operational (2500-2502)
4. **Configuration**: Many RPC nodes missing standard config files
5. **Services**: Several nodes running but systemd services show inactive

**Status**: 📊 **REVIEW COMPLETE - ACTION REQUIRED**
