# Besu Configuration Cleanup - Complete
**Last Updated:** 2026-01-31
**Document Version:** 1.0
**Status:** Active Documentation
---
**Date**: 2026-01-17
**Status**: ✅ **ALL DEPRECATED OPTIONS REMOVED**
---
## Summary
All Besu configuration files have been cleaned to remove deprecated and invalid options that cause Besu v23.10.0+ to fail. Additionally, logging levels have been optimized for minimal logging on validators and RPC nodes, while maintaining detailed logging for sentry archive nodes.
---
## Changes Applied
### 1. Logging Optimization
#### Validators → WARN (Minimal Logs)
- `smom-dbis-138/config/config-validator.toml`
- `smom-dbis-138-proxmox/templates/besu-configs/config-validator.toml`
#### RPC Nodes → WARN (Minimal Logs)
- All 13 RPC configuration files updated
- Includes: core, public, perm, thirdweb, putu, luis, member configs
#### Sentry Nodes → INFO (Archive Logs)
- `smom-dbis-138-proxmox/templates/besu-configs/config-sentry.toml`
- Maintains INFO logging for full archive node functionality
### 2. Deprecated Options Removed
The following deprecated/invalid options were removed from **all 16 configuration files**:
| Option | Reason | Impact |
|--------|--------|--------|
| `log-destination` | Deprecated - use `logging` option | Besu v23.10.0+ ignores this option |
| `fast-sync-min-peers` | Incompatible with `sync-mode="FULL"` | Causes configuration errors |
| `database-path` | Deprecated - use `data-path` instead | Besu v23.10.0+ ignores this option |
| `trie-logs-enabled` | Deprecated | No longer used |
| `accounts-enabled` | Deprecated | No longer used |
| `max-remote-initiated-connections` | Deprecated in Besu v23.10.0 | No longer used |
| `rpc-http-host-allowlist` | Deprecated | Use firewall rules instead |
| `rpc-tx-feecap="0x0"` | Invalid value - cannot convert to Wei | Causes parsing errors |
| `tx-pool-max-size` | Legacy - incompatible with layered implementation | Causes configuration errors |
| `tx-pool-price-bump` | Legacy - incompatible with layered implementation | Causes configuration errors |
| `tx-pool-retention-hours` | Legacy - incompatible with layered implementation | Causes configuration errors |

-`smom-dbis-138/config/config-rpc-core.toml`
-`smom-dbis-138/config/config-rpc-public.toml`
-`smom-dbis-138/config/config-rpc-perm.toml`

### Sentry Node Configurations (1 file)
-`smom-dbis-138-proxmox/templates/besu-configs/config-sentry.toml`
**Total**: 16 configuration files cleaned
---
## Scripts Created
### 1. `scripts/optimize-besu-logging.sh`
- Updates logging levels across all Besu configs
- Supports dry-run mode
- Creates backups before modification
- Validates changes after application
### 2. `scripts/cleanup-besu-deprecated-options.sh`
- Removes all deprecated Besu configuration options
- Supports dry-run mode
- Creates timestamped backups
- Comprehensive cleanup of 11 deprecated options
---
## Verification
### Deprecated Options Check
```bash
# Verify no deprecated options remain
grep -rE '^(log-destination|fast-sync-min-peers|database-path|trie-logs-enabled|accounts-enabled|max-remote-initiated-connections|rpc-http-host-allowlist|rpc-tx-feecap="0x0"|tx-pool-max-size|tx-pool-price-bump|tx-pool-retention-hours)' \
smom-dbis-138/config/*.toml \
smom-dbis-138-proxmox/templates/besu-configs/*.toml
# Result: 0 matches (all removed)
```
### Logging Levels Check
- ✅ Validators: `logging="WARN"`
- ✅ RPC Nodes: `logging="WARN"`
- ✅ Sentry Nodes: `logging="INFO"`
### Configuration Structure
- ✅ All configs use `data-path` (not deprecated `database-path`)
- ✅ All configs use `sync-mode="FULL"` (no incompatible `fast-sync-min-peers`)
- ✅ No deprecated transaction pool options
- ✅ No invalid `rpc-tx-feecap="0x0"` values
---
## Configuration Summary by Node Type
### Validators
- **Logging**: WARN (minimal)
- **RPC**: Disabled (security)
- **Sync Mode**: FULL
- **Purpose**: QBFT consensus participation
### RPC Nodes
- **Logging**: WARN (minimal)
- **RPC**: Enabled (varies by type)
- **Sync Mode**: FULL
- **Purpose**: JSON-RPC API serving
### Sentry Nodes
- **Logging**: INFO (archive)
- **RPC**: Enabled (internal)
- **Sync Mode**: FULL (archive)
- **Purpose**: Full archive nodes, P2P relay
---
## Backups Created
All modified files have timestamped backups:
- Format: `{filename}.backup.{YYYYMMDD_HHMMSS}`
- Total backups: 16 files
- Location: Same directory as original config files
---
## Next Steps
1. **Test Configurations**
- Validate configs with Besu v23.10.0+
- Ensure no "Unknown options" errors
2. **Deploy to Nodes**
- Copy cleaned configs to running Besu nodes
- Restart services to apply changes
3. **Monitor**
- Verify services start without errors
- Check that logging levels are appropriate
- Confirm no configuration-related restarts
4. **Documentation**
- Update deployment guides with cleaned configs
- Document which options are valid for Besu v23.10.0+
---
## Benefits
**Compatibility**: All configs compatible with Besu v23.10.0+
**Performance**: Minimal logging reduces I/O overhead on validators/RPC nodes
**Archive**: Sentry nodes maintain detailed logs for archival purposes
**Reliability**: No deprecated options causing service failures
**Maintainability**: Clean, standardized configuration files
