## MikroTik RouterOS - Detailed Analysis
### Current Coverage: 65-70% Overall Parity
#### ✅ **Excellent Coverage** (100% parity):
- **Temperature**: Optical module temp, system gauge temp
- **Voltage**: Optical supply, POE voltage (per port), gauge voltage, high-load voltage
- **Current**: Optical Tx bias, POE current (per port), gauge current
- **Power**: POE power (per port), gauge power
- **dBm**: Optical Tx/Rx power
- **Fanspeed**: System fans via gauge table
- **Count**: DHCP leases, firewall connections (total/IPv4/IPv6)
- **State**: Optical Rx loss/Tx fault, POE status, gauge status, 60GHz connection/mode
All OIDs match LibreNMS exactly. All divisors correct.
#### ❌ **Critical Gaps** (0% coverage):
**Wireless Sensor Discovery** - Missing 11 sensor types:
1. **Clients (Station Count)** - `mtxrWlApTable` - CRITICAL for capacity planning
2. **CCQ (Channel Capacity Quality)** - `mtxrWlApTable`, `mtxrWlStatTable` - Link quality indicator
3. **Frequency** - `mtxrWlApTable`, `mtxrWlStatTable`, `mtxrWl60GTable` - Channel information
4. **Noise Floor** - `mtxrWlApTable` - RF environment quality
5. **Rate (Tx/Rx)** - `mtxrWlApTable`, `mtxrWlStatTable` - Throughput monitoring
6. **RSSI (Signal Strength)** - `mtxrWl60GTable` - Connection quality
7. **Quality** - `mtxrWl60GTable` - Signal quality metric
8. **Distance** - `mtxrWl60GStaTable` - Link distance measurement
9. **RSRQ (LTE)** - `mtxrLTEModemTable` - LTE signal quality
10. **RSRP (LTE)** - `mtxrLTEModemTable` - LTE reference signal power
11. **SINR (LTE)** - `mtxrLTEModemTable` - LTE signal-to-noise
**Advanced Features Missing**:
- Transceiver discovery (vendor, serial, wavelength metadata)
- QoS monitoring (queue stats, traffic shaping)
- VLAN discovery
- OS polling (device-level metrics)
#### Implementation Complexity:
- **Wireless sensors**: HIGH - Requires new YAML tables + sensor mappings (similar to LibreNMS `discoverWirelessClients()`, `discoverWirelessCcq()`, etc.)
- **Transceiver discovery**: MEDIUM - Metadata extraction from optical modules
- **QoS/VLAN**: MEDIUM-HIGH - New MIB tables and discovery logic
---
## Ubiquiti Platforms - Detailed Analysis
### AirOS (airMAX) - 95% Parity ✅
**Excellent coverage** of all core wireless metrics:
- Frequency, Capacity, CCQ, Client count, Distance, Noise floor
- Tx Power, Signal quality, Tx/Rx rate, RSSI
- Channel utilization (Tx/Rx), CPU load, Temperature
- GPS fix status and coordinates
**Minor gap**: Per-chain RSSI discovery (LibreNMS walks per chain, Towerops has combined)
---
### UniFi - 80% Parity ✅
**Good coverage** of access point metrics:
- Clients (2.4GHz and 5GHz per SSID)
- CCQ (per radio with 10x divisor)
- Tx Power (per radio)
- Channel utilization (total, self-rx, self-tx)
**Missing**:
- Channel-to-frequency conversion (static OID doesn't update with channel changes)
- Other BSS utilization
- Processor discovery
---
### AirFiber AF-LTU - 40% Parity ⚠️ **CRITICAL GAPS**
**Current coverage**:
- ✅ Radio role (AP/CPE), GPS status/fix/satellites
- ✅ CPU usage
**Missing CRITICAL sensors**:
- ❌ **TX Modulation Rate** (state sensor with QAM mappings) - **MOST CRITICAL**
- ❌ **RX Modulation Rate** (state sensor) - **MOST CRITICAL**
- ❌ Frequency
- ❌ Distance (with 1000x divisor for km)
- ❌ TX/RX Capacity (with 1000x divisor for Mbps)
- ❌ RX Power (per chain 0/1)
- ❌ RX Ideal Power (per chain)
- ❌ TX EIRP
- ❌ Signal Level (per chain quality)
**Production Impact**: Without modulation rate sensors, operators cannot diagnose link quality degradation. These state sensors show when links drop from high QAM to low QAM due to interference or alignment issues.
---
### AirFiber AF60 - 35% Parity ⚠️ **CRITICAL GAPS**
**Current coverage**:
- ✅ Radio role (AP/CPE), GPS status/fix/satellites
- ✅ CPU usage
**Missing CRITICAL sensors**:
- ❌ **TX MCS Rate** (state sensor, 9 states from 1X to 9X) - **MOST CRITICAL**
- ❌ **RX MCS Rate** (state sensor) - **MOST CRITICAL**
- ❌ RSSI (Local/Remote per-chain)
- ❌ SNR (Signal-to-Noise Ratio per-chain)
- ❌ Frequency
- ❌ Distance (with 1000x divisor)
- ❌ TX/RX Capacity (with 1000x divisor)
- ❌ Active Link Status (Main/Backup state)
**Production Impact**: MCS rate is THE key indicator of link health on AF60. Without it, capacity numbers are meaningless because operators can't see WHY throughput changed.
---
### EdgeOS - 80% Parity ✅ **Towerops Advantage**
**Towerops has BETTER coverage than LibreNMS**:
- ✅ CPU load, PSU sensors (voltage, current, power)
- ✅ Battery metrics (charge level, runtime remaining)
- ✅ Temperature, fan speed
- ✅ PSU operational/charging/status states
LibreNMS only does basic Entity-MIB hardware inventory.
---
### EdgeOLT - 95% Parity ✅ **Towerops Advantage**
**Towerops has comprehensive OLT coverage**:
- ✅ SFP status, ONU online status, ONU count
- ✅ Temperature, fan speed
- ✅ ONU RX/TX power (dBm with 100x divisor)
LibreNMS only discovers ports, not optical power metrics.

## Conclusion
The analysis reveals that Towerops has **excellent basic sensor coverage** but is **missing critical wireless link quality indicators** for point-to-point devices (AirFiber) and **complete wireless monitoring** for MikroTik.
**Immediate action required**: Implement Tier 1 (AirFiber MCS/modulation rate state sensors) to enable production link health monitoring.
**Strategic priority**: MikroTik wireless sensor discovery (Tier 4) is the largest gap but requires significant effort. Should be planned as a dedicated sprint after Tiers 1-3 are complete.
