# 06 — Parsers

## Framework

Parsers live in `internal/parser/` and vendor implementations live in `internal/parser/vendors/`.

Core behavior:
- registration uses `init()` side effects
- all registered parsers run `Detect()`
- the highest-confidence parser wins
- generic fallback stays last and low-confidence

`VendorParser` contract:

```go
type VendorParser interface {
    Name() string
    Vendor() string
    Version() string
    Detect(files []ExtractedFile) int
    Parse(files []ExtractedFile) (*models.AnalysisResult, error)
}
```

## Adding a parser

1. Create `internal/parser/vendors/<vendor>/`
2. Start from `internal/parser/vendors/template/parser.go.template`
3. Implement `Detect()` and `Parse()`
4. Add a blank import in `internal/parser/vendors/vendors.go`
5. Add at least one positive and one negative detection test

## Data quality rules

### System firmware only in `hardware.firmware`

`hardware.firmware` must contain system-level firmware only.
Device-bound firmware belongs on the device record and must not be duplicated at the top level.

### Strip embedded MAC addresses from model names

If a source embeds ` - XX:XX:XX:XX:XX:XX` in a model/name field, remove that suffix before storing it.

### Use `pci.ids` for empty or generic PCI model names

When `vendor_id` and `device_id` are known but the model name is missing or generic, resolve the name via `internal/parser/vendors/pciids`.

## Active vendor coverage

| Vendor ID | Input family | Notes |
|-----------|--------------|-------|
| `dell` | TSR ZIP archives | Broad hardware, firmware, sensors, lifecycle events |
| `easy_bee` | `bee-support-*.tar.gz` | Imports embedded `export/bee-audit.json` snapshot from reanimator-easy-bee bundles |
| `h3c_g5` | H3C SDS G5 bundles | INI/XML/CSV-driven hardware and event parsing |
| `h3c_g6` | H3C SDS G6 bundles | Similar flow with G6-specific files |
| `hpe_ilo_ahs` | HPE iLO Active Health System (`.ahs`) | Proprietary `ABJR` container with gzip-compressed `zbb` members; parser combines SMBIOS-style inventory strings and embedded Redfish storage JSON |
| `inspur` | onekeylog archives | FRU/SDR plus optional Redis enrichment |
| `lenovo_xcc` | Lenovo XCC mini-log ZIP archives | JSON inventory + platform event logs |
| `nvidia` | HGX Field Diagnostics | GPU- and fabric-heavy diagnostic input |
| `nvidia_bug_report` | `nvidia-bug-report-*.log.gz` | dmidecode, lspci, NVIDIA driver sections |
| `unraid` | Unraid diagnostics/log bundles | Server and storage-focused parsing |
| `xfusion` | xFusion iBMC `tar.gz` dump / file export | AppDump + RTOSDump + LogDump merge for hardware and firmware |
| `xigmanas` | XigmaNAS plain logs | FreeBSD/NAS-oriented inventory |
| `generic` | fallback | Low-confidence text fallback when nothing else matches |

## Practical guidance

- Be conservative with high detect scores
- Prefer filling missing fields over overwriting stronger source data
- Keep parser version constants current when behavior changes
- Any new vendor-specific filtering or dedup logic must ship with tests for that vendor format

**Archive format:** Unraid diagnostics archive contents (text-heavy diagnostics directories).

**Detection:** Combines filename/path markers (`diagnostics-*`, `unraid-*.txt`, `vars.txt`)
with content markers (e.g. `Unraid kernel build`, parity data markers).

**Extracted data (current):**
- Board / BIOS metadata (from motherboard/system files)
- CPU summary (from `lscpu.txt`)
- Memory modules (from diagnostics memory file)
- Storage devices (from `vars.txt` + SMART files)
- Syslog events

### H3C SDS G5 (`h3c_g5`)

**Status:** Ready (v1.0.0). Tested on H3C UniServer R4900 G5 SDS archives.

**Archive format:** `.sds` (tar archive)

**Detection:** `hardware_info.ini`, `hardware.info`, `firmware_version.ini`, `user/test*.csv`, plus H3C markers.

**Extracted data (current):**
- Board/FRU inventory (`FRUInfo.ini`, `board_info.ini`)
- Firmware list (`firmware_version.ini`)
- CPU inventory (`hardware_info.ini`)
- Memory DIMM inventory (`hardware_info.ini`)
- Storage inventory (`hardware.info`, `storage_disk.ini`, `NVMe_info.txt`, RAID text enrichments)
- Logical RAID volumes (`raid.json`, `Storage_RAID-*.txt`)
- Sensor snapshot (`sensor_info.ini`)
- SEL events (`user/test.csv`, `user/test1.csv`, fallback `Sel.json` / `sel_list.txt`)

---

### H3C SDS G6 (`h3c_g6`)

**Status:** Ready (v1.0.0). Tested on H3C UniServer R4700 G6 SDS archives.

**Archive format:** `.sds` (tar archive)

**Detection:** `CPUDetailInfo.xml`, `MemoryDetailInfo.xml`, `firmware_version.json`, `Sel.json`, plus H3C markers.

**Extracted data (current):**
- Board/FRU inventory (`FRUInfo.ini`, `board_info.ini`)
- Firmware list (`firmware_version.json`)
- CPU inventory (`CPUDetailInfo.xml`)
- Memory DIMM inventory (`MemoryDetailInfo.xml`)
- Storage inventory + capacity/model/interface (`storage_disk.ini`, `Storage_RAID-*.txt`, `NVMe_info.txt`)
- Logical RAID volumes (`raid.json`, fallback from `Storage_RAID-*.txt` when available)
- Sensor snapshot (`sensor_info.ini`)
- SEL events (`user/Sel.json`, fallback `user/sel_list.txt`)

---

### HPE iLO AHS (`hpe_ilo_ahs`)

**Status:** Ready (v1.0.0). Tested on HPE ProLiant Gen11 `.ahs` export from iLO 6.

**Archive format:** `.ahs` single-file Active Health System export.

**Detection:** Single-file input with `ABJR` container header and HPE AHS member names
such as `CUST_INFO.DAT`, `*.zbb`, `ilo_boot_support.zbb`.

**Extracted data (current):**
- System board identity (manufacturer, model, serial, part number)
- iLO / System ROM / SPS top-level firmware
- CPU inventory (model-level)
- Memory DIMM inventory for populated slots
- PSU inventory
- PCIe / OCP NIC inventory from SMBIOS-style slot records
- Storage controller and physical drives from embedded Redfish JSON inside `zbb` members
- Basic iLO event log entries with timestamps when present

**Implementation note:** The format is proprietary. Parser support is intentionally hybrid:
container parsing (`ABJR` + gzip) plus structured extraction from embedded Redfish objects and
printable SMBIOS/FRU payloads. This is sufficient for inventory-grade parsing without decoding the
entire internal `zbb` schema.

### xFusion iBMC Dump / File Export (`xfusion`)

**Status:** Ready (v1.1.0). Tested on xFusion G5500 V7 `tar.gz` exports.

**Archive format:** `tar.gz` dump exported from the iBMC UI, including `AppDump/`, `RTOSDump/`,
and `LogDump/` trees.

**Detection:** `AppDump/FruData/fruinfo.txt`, `AppDump/card_manage/card_info`,
`RTOSDump/versioninfo/app_revision.txt`, and `LogDump/netcard/netcard_info.txt`.

**Extracted data (current):**
- Board / FRU inventory from `fruinfo.txt`
- CPU inventory from `CpuMem/cpu_info`
- Memory DIMM inventory from `CpuMem/mem_info`
- GPU inventory from `card_info`
- OCP NIC inventory by merging `card_info` with `LogDump/netcard/netcard_info.txt`
- PSU inventory from `BMC/psu_info.txt`
- Physical storage from `StorageMgnt/PhysicalDrivesInfo/*/disk_info`
- System firmware entries from `RTOSDump/versioninfo/app_revision.txt`
- Maintenance events from `LogDump/maintenance_log`

---

### Generic text fallback (`generic`)

**Status:** Ready (v1.0.0).

**Confidence:** 15 (lowest — only matches if no other parser scores higher)

**Purpose:** Fallback for any text file or single `.gz` file not matching a specific vendor.

**Behavior:**
- If filename matches `nvidia-bug-report-*.log.gz`: extracts driver version and GPU list.
- Otherwise: confirms file is text (not binary) and records a basic "Text File" event.
