✅ **Complete**:
|
||||
- Backend API with token authentication
|
||||
- Agent management UI
|
||||
- Organization/equipment-level configuration
|
||||
- **Hierarchical agent assignment** (Equipment > Site > Organization)
|
||||
- Organization/site/equipment-level configuration
|
||||
- Rust agent architecture (compiles successfully)
|
||||
- **SNMP client fully implemented** (GET and WALK operations)
|
||||
- SQLite buffering
|
||||
- Docker deployment files
|
||||
- 401 tests passing
|
||||
|
||||
🔄 **In Progress**:
|
||||
- SNMP library integration (simplified implementation)
|
||||
- Protocol Buffers integration for all API endpoints
|
||||
- 775 tests passing
|

|

## Critical Path to Production
|
||||
|
||||
### 1. Complete SNMP Integration (Priority: HIGH)
|
||||
### 1. Integration Testing (Priority: HIGH) ⬅️ **START HERE**
|
||||
|
||||
**Problem**: The Rust `snmp` crate v0.2 API differs from the initially designed implementation. Current code compiles but returns errors for actual SNMP operations.
|
||||
|
||||
**Options**:
|
||||
|
||||
#### Option A: Complete `snmp` crate integration (Recommended)
|
||||
**Effort**: 4-8 hours
|
||||
**File**: `towerops-agent/src/snmp/client.rs`
|
||||
|
||||
Research the correct `snmp` crate 0.2 API:
|
||||
```bash
|
||||
# In towerops-agent/
|
||||
cargo doc --open --package snmp
|
||||
```
|
||||
|
||||
Key methods to implement:
|
||||
- `SyncSession::new()` - Create session
|
||||
- `session.get()` or similar - Perform GET
|
||||
- `session.getnext()` or similar - Perform GETNEXT (for WALK)
|
||||
- Error handling for timeouts, auth failures
|
||||
|
||||
**Reference**: Check `snmp` crate examples and tests
|
||||
|
||||
#### Option B: Use alternative SNMP library
|
||||
**Effort**: 6-12 hours
|
||||
|
||||
Alternatives:
|
||||
- `snmp-mp` - More actively maintained
|
||||
- `snmp-parser` - Lower level, more control
|
||||
- `rasn-snmp` - ASN.1 based
|
||||
|
||||
Replace in `Cargo.toml` and reimplement `client.rs`.
|
||||
|
||||
#### Option C: Implement basic SNMP manually
|
||||
**Effort**: 16-24 hours
|
||||
|
||||
Implement SNMPv1/v2c protocol directly:
|
||||
- ASN.1 BER encoding/decoding
|
||||
- UDP socket communication
|
||||
- PDU construction
|
||||
|
||||
**Not recommended** - reinventing the wheel.

||||
