# Predictalytics
|
||||||
|
|
||||||
|
Betriebsdokumentation zur Anbindung an das Deployment Center (Lizenz, Watchdog,
|
||||||
|
Updates, Fehler-Stream): [`docs/BETRIEB-Deploymentcenter.md`](docs/BETRIEB-Deploymentcenter.md).
|
||||||
|
|
||||||
|
## Zentraler Bugtracker — Deployment Center
|
||||||
|
|
||||||
|
Erfasse unbehandelte Fehler, geplante Verbesserungen und Ideen im zentralen
|
||||||
|
Deployment Center. Basis-URL: `https://dc.mhdf.de`
|
||||||
|
|
||||||
|
### Zugang
|
||||||
|
Token steht in der Umgebungsvariable `DC_TOKEN`.
|
||||||
|
Header: `Authorization: Bearer $DC_TOKEN`
|
||||||
|
|
||||||
|
Ist `DC_TOKEN` nicht gesetzt, melde nichts und weise stattdessen darauf hin —
|
||||||
|
die Endpunkte antworten sonst mit `401 unauthorized`.
|
||||||
|
|
||||||
|
Die vollständige Schnittstellenbeschreibung liegt maschinenlesbar unter
|
||||||
|
`GET /api/openapi.json`, das Handbuch unter `/docs/`.
|
||||||
|
|
||||||
|
### Projekt
|
||||||
|
Dieses Projekt ist `predictalytics`.
|
||||||
|
Repo: `http://192.168.178.10:8418/Richard/Predictalytics`
|
||||||
|
Fällt dir ein Fehler im Deployment Center selbst auf, melde ihn unter
|
||||||
|
`deploymentcenter`.
|
||||||
|
|
||||||
|
### Etwas melden
|
||||||
|
`POST /api/bugtracker/v1/report`
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"project_slug": "predictalytics",
|
||||||
|
"type": "bug",
|
||||||
|
"title": "Kurze, aussagekräftige Zusammenfassung",
|
||||||
|
"description": "Unter welchen Bedingungen tritt es auf?",
|
||||||
|
"error_message": "Exakte Fehlermeldung",
|
||||||
|
"stack_trace": "Vollständiger Stacktrace",
|
||||||
|
"severity": "high",
|
||||||
|
"environment": "production",
|
||||||
|
"build_version": "v1.0.0",
|
||||||
|
"repo_url": "http://192.168.178.10:8418/Richard/Predictalytics",
|
||||||
|
"git_branch": "main",
|
||||||
|
"commit_sha": "a21536f",
|
||||||
|
"file_path": "src/Predictalytics.Worker/Services/TraderAnalyticsWorker.cs",
|
||||||
|
"line_no": 152,
|
||||||
|
"client_ref": "eindeutige-id-dieses-laufs"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Setze immer `client_ref`** — ein wiederholter Aufruf mit demselben Wert legt
|
||||||
|
kein Duplikat an. Gib nach Möglichkeit `file_path` und `line_no` an; das spart
|
||||||
|
dem nächsten Agenten das Parsen des Stacktrace.
|
||||||
|
|
||||||
|
Schweregrade: `idea` (Gedanke für später), `wishlist` (Backlog),
|
||||||
|
`low`, `medium`, `high`, `critical`.
|
||||||
|
|
||||||
|
### Arbeit übernehmen
|
||||||
|
Bevor du an einem Item arbeitest, übernimm es — sonst arbeiten zwei Agenten
|
||||||
|
parallel am selben Problem:
|
||||||
|
|
||||||
|
```
|
||||||
|
POST /api/bugtracker/v1/manage?action=next
|
||||||
|
Body: {"project_slug": "predictalytics", "limit": 1}
|
||||||
|
```
|
||||||
|
|
||||||
|
Antwortet der Server mit `409 already_claimed`, nimm das nächste Item.
|
||||||
|
Die Reservierung läuft nach 30 Minuten ab; `action=claim` auf dieselbe ID
|
||||||
|
erneuert sie.
|
||||||
|
|
||||||
|
### Fortschritt festhalten
|
||||||
|
```
|
||||||
|
POST /api/bugtracker/v1/manage?action=comment&id=<ID>
|
||||||
|
Body: {"comment": "Was du herausgefunden hast", "action_taken": "investigated"}
|
||||||
|
```
|
||||||
|
|
||||||
|
`action_taken`: `investigated`, `fix_proposed`, `pr_opened`, `needs_human`,
|
||||||
|
`blocked`, `commented`.
|
||||||
|
|
||||||
|
### Abschließen
|
||||||
|
```
|
||||||
|
POST /api/bugtracker/v1/manage?action=resolve&id=<ID>
|
||||||
|
Body: {"resolved_in_build": "v1.0.1", "resolution_notes": "Was geändert wurde"}
|
||||||
|
```
|
||||||
|
|
||||||
|
Kommst du nicht weiter, gib das Item zurück statt es blockieren zu lassen:
|
||||||
|
```
|
||||||
|
POST /api/bugtracker/v1/manage?action=release&id=<ID>
|
||||||
|
Body: {"note": "Grund"}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Laufzeitfehler
|
||||||
|
Die Anwendung meldet Error/Fatal selbst über `POST /api/errors/v1/report`
|
||||||
|
(`Services/DcErrorReporter.cs`) — dort nichts von Hand nachreichen.
|
||||||
|
|
||||||
|
### Release melden
|
||||||
|
Nach einem Release schließen sich Items mit passendem `resolved_in_build`
|
||||||
|
automatisch:
|
||||||
|
```
|
||||||
|
POST /api/updateservice/v1/publish
|
||||||
|
Body: {"product_slug": "predictalytics", "version": "1.0.1",
|
||||||
|
"download_url": "...", "sha256_hash": "...", "git_commit": "..."}
|
||||||
|
```
|
||||||
|
|
||||||
|
Die Version in `src/Predictalytics.WinFormsHost/Predictalytics.WinFormsHost.csproj`
|
||||||
|
(`<Version>`) muss dazu passen — sie ist es, die der Client als installierte
|
||||||
|
Version meldet.
|
||||||
|
|
||||||
|
### Fehlerbehandlung
|
||||||
|
Antworten haben die Form `{"status":"error","error":{"code":"…"}}`.
|
||||||
|
Reagiere auf `code`, nicht auf den Text:
|
||||||
|
- `401 unauthorized` — Token prüfen, nicht wiederholen
|
||||||
|
- `409 already_claimed` — nächstes Item nehmen
|
||||||
|
- `429 rate_limited` — Intervall verdoppeln, später erneut

# Betrieb: Deployment Center
|
||||||
|
|
||||||
|
Das **Deployment Center** (`https://dc.mhdf.de`, Schwester-Repo
|
||||||
|
`J:\Softwareprojekte\Deploymentcenter`) hat die beiden früheren Einzelserver abgelöst:
|
||||||
|
|
||||||
|
| Vorher | Jetzt |
|
||||||
|
|---|---|
|
||||||
|
| WatchDog auf `watchdog.mhdf.de`, `POST /api/heartbeat`, Header `X-Watchdog-Key` | Deployment Center, `POST /api/watchdog/v1/ping`, `Authorization: Bearer` |
|
||||||
|
| LicenseLabrador auf `license.mhdf.de`, Ed25519-signierte Envelopes | Deployment Center, `POST /api/license/v1/validate`, Hardware-ID v2 |
|
||||||
|
| — | UpdateService, Fehler-Stream und Bugtracker (neu) |
|
||||||
|
|
||||||
|
Die Anbindung sitzt im `Predictalytics.WinFormsHost` und referenziert das
|
||||||
|
C#-SDK `Deploymentcenter.Client` aus dem Schwester-Repo:
|
||||||
|
|
||||||
|
```
|
||||||
|
..\..\..\..\Deploymentcenter\client-dotnet\Deploymentcenter.Client\Deploymentcenter.Client.csproj
|
||||||
|
```
|
||||||
|
|
||||||
|
Das Repo muss also neben dem Predictalytics-Checkout liegen. `LicenseLabrador`
|
||||||
|
und `WatchDog` werden nicht mehr gebraucht.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 0. Was einmalig zu tun ist
|
||||||
|
|
||||||
|
1. Im Deployment Center unter **Token-Verwaltung → Master-Token erstellen** ein
|
||||||
|
Token mit den Rechten **`watchdog:ping`** und **`bugtracker:report`** anlegen.
|
||||||
|
2. Im Host unter **Settings → Deployment Center → API Token** eintragen.
|
||||||
|
Der alte `X-Watchdog-Key` funktioniert nicht mehr — es ist ein anderer Server.
|
||||||
|
3. Beim ersten Start erscheint einmalig der Lizenzdialog: der Lizenzschlüssel muss
|
||||||
|
erneut eingegeben werden, weil die Aktivierung jetzt am Deployment Center hängt.
|
||||||
|
4. Serverseitig muss der **Evaluator-Cron** laufen — ohne ihn bleibt ein
|
||||||
|
abgestürzter Dienst dauerhaft grün:
|
||||||
|
```
|
||||||
|
* * * * * curl -fsS -H "Authorization: Bearer <SHARED_KEY>" https://dc.mhdf.de/api/watchdog/v1/evaluate > /dev/null
|
||||||
|
```
|
||||||
|
|
||||||
|
Der Token landet in der `settings.json` neben der Exe (nicht im Git).
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 1. Konfiguration (PropertyGrid, Kategorie „Deployment Center")
|
||||||
|
|
||||||
|
| Feld | Default | Bedeutung |
|
||||||
|
|---|---|---|
|
||||||
|
| `Server URL` | `https://dc.mhdf.de` | **schreibgeschützt**, siehe unten |
|
||||||
|
| `API Token` | *(leer)* | `Authorization: Bearer`. Ohne Token: keine Heartbeats, keine Fehlermeldungen. |
|
||||||
|
| `Heartbeat aktiv` | `true` | Dead-Man's-Switch an/aus |
|
||||||
|
| `Monitor Source` | `Predictalytics` | Monitor-Name im Dashboard (Auto-Registrierung beim ersten Ping) |
|
||||||
|
| `Monitor Instance` | `default` | falls mehrere Instanzen laufen |
|
||||||
|
| `Heartbeat-Intervall (Sekunden)` | `60` | `warning` nach 2×, `down` nach 4× |
|
||||||
|
| `Fehler melden` | `true` | Error/Fatal an den Fehler-Stream |
|
||||||
|
| `Update-Prüfung beim Start` | `true` | prüft nur, installiert nichts von selbst |
|
||||||
|
| `Update-Kanal` | `prod` | `prod`, `beta` oder `dev` |
|
||||||
|
|
||||||
|
**Warum ist die Server-URL nicht einstellbar?** Sie entscheidet, wohin die
|
||||||
|
Lizenzprüfung geht und woher Update-Pakete kommen. Ein einstellbarer Endpoint
|
||||||
|
würde erlauben, die App auf einen gefälschten Lizenz- oder Update-Server zu
|
||||||
|
zeigen. Sie steht als Konstante in `Services/DcConfig.cs`.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 2. Watchdog (Dead-Man's-Switch)
|
||||||
|
|
||||||
|
`Services/DcHeartbeatService.cs` sendet alle *n* Sekunden einen
|
||||||
|
`POST /api/watchdog/v1/ping`. Beim regulären Schließen geht ein Ping mit
|
||||||
|
`status: "stopped"` raus — der Evaluator lässt einen so beendeten Monitor in
|
||||||
|
Ruhe, bis wieder ein normaler Heartbeat eintrifft. Ohne das folgt wenige Minuten
|
||||||
|
nach jedem geordneten Beenden ein Fehlalarm.
|
||||||
|
|
||||||
|
**Ein Ausfall des Deployment Centers darf Predictalytics nie beeinträchtigen.**
|
||||||
|
Alle Aufrufe sind best effort; der erste Fehlschlag wird als Warnung geloggt,
|
||||||
|
Folgefehler nur noch auf Debug-Level (keine Log-Flut). Wird das Token abgelehnt
|
||||||
|
(`401`/`403`), stellt der Dienst die Versuche ganz ein — Wiederholen kann daran
|
||||||
|
nichts ändern.
|
||||||
|
|
||||||
|
### Mitgesendeter Gesundheitszustand
|
||||||
|
|
||||||
|
Ein Heartbeat beweist nur, dass ein Timer läuft. Deshalb schickt die App ihren
|
||||||
|
selbst ermittelten Zustand mit:
|
||||||
|
|
||||||
|
| `checks` | Bedeutung |
|
||||||
|
|---|---|
|
||||||
|
| `db` | `SELECT 1` gegen die konfigurierte MySQL, gedeckelt auf 5 s. Schlägt sie fehl, stuft der Server den Heartbeat auf `warning`. |
|
||||||
|
|
||||||
|
| `metrics` | Bedeutung |
|
||||||
|
|---|---|
|
||||||
|
| `uptime_sec` | Laufzeit des Prozesses |
|
||||||
|
| `workers_running` | 0/1 — Hintergrund-Worker gestartet |
|
||||||
|
| `webserver_running` | 0/1 — eingebetteter Kestrel gestartet |
|
||||||
|
| `memory_mb` | verwalteter Heap |
|
||||||
|
| `db_size_mb` | zuletzt ermittelte Datenbankgröße |
|
||||||
|
|
||||||
|
Zusätzlich geht seit Server 2.1 das Feld `version` mit — im Dashboard ist damit
|
||||||
|
sichtbar, welcher Build läuft, und ein Ausfall lässt sich einem Rollout zuordnen.
|
||||||
|
|
||||||
|
Gestoppte Worker sind **bewusst kein** fehlgeschlagener Check: das ist ein
|
||||||
|
gewollter Betriebszustand und würde den Monitor sonst dauerhaft auf `warning`
|
||||||
|
halten. Der Zustand steckt als Metrik drin und lässt sich dort auswerten.
|
||||||
|
|
||||||
|
Metriken werden serverseitig 14 Tage lang mit Verlauf gehalten
|
||||||
|
(`GET /api/watchdog/v1/metrics?source=Predictalytics`).
|
||||||
|
|
||||||
|
### Maschine mit überwachen
|
||||||
|
|
||||||
|
Der Heartbeat deckt nur *diesen* Prozess ab. Für die Maschine selbst gehört
|
||||||
|
zusätzlich ein OS-Agent auf den Host (siehe
|
||||||
|
`Deploymentcenter/docs/WATCHDOG_INTEGRATION_GUIDE.md`). Läuft beides, sollte im
|
||||||
|
WebUI unter **WatchDog → System-Hierarchie** die *Übergeordnete Entität* des
|
||||||
|
Predictalytics-Monitors auf den Host gesetzt werden — dann erzeugt ein
|
||||||
|
Maschinenausfall eine Meldung statt zwei.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 3. Lizenzierung
|
||||||
|
|
||||||
|
`Services/LicenseGuard.cs` prüft beim Start, ob eine nutzbare Lizenz vorliegt;
|
||||||
|
`Program.Main` bricht sonst ab, bevor die MainForm entsteht. Ohne gültige Lizenz
|
||||||
|
erscheint `Services/LicenseDialog.cs` zur Key-Eingabe.
|
||||||
|
|
||||||
|
- **Produkt-Slug:** `predictalytics`
|
||||||
|
- **Hardware-ID v2:** `2:win:<sha256>` aus `HKLM\...\Cryptography\MachineGuid`.
|
||||||
|
Der Rechnername steckt **nicht** im Hash — Umbenennen kostet keinen
|
||||||
|
Aktivierungsplatz.
|
||||||
|
- **Offline-Cache:** AES-256-GCM + DPAPI unter `%AppData%\predictalytics\license\state.dat`
|
||||||
|
(Schema 3 seit SDK 2.1, Schema 2 wird noch gelesen). Dort liegt auch der
|
||||||
|
Lizenzschlüssel — `LicenseClient.TryGetCachedKey()` holt ihn beim Start, damit
|
||||||
|
ohne Dialog revalidiert werden kann.
|
||||||
|
- **Revalidierung zur Laufzeit:** alle 12 h.
|
||||||
|
- **Gemeldete Version:** `LicenseClient.DefaultAppVersion` wird in `Program.Main`
|
||||||
|
auf `BuildInfo.Version` gesetzt; ohne das trüge jede Installation in der
|
||||||
|
Aktivierungsliste dieselbe „1.0.0".
|
||||||
|
|
||||||
|
### Offline-Gnadenfrist
|
||||||
|
|
||||||
|
Seit Server 2.1 ist sie **echt begrenzt**: der Server liefert `cache_ttl_hours`
|
||||||
|
(je Projekt im WebUI, Standard 168 h = 7 Tage). Vorher galt faktisch das
|
||||||
|
Lizenz-Ablaufdatum, bei einer Lizenz bis 2040 also unbegrenzt.
|
||||||
|
|
||||||
|
Läuft die Frist in weniger als 48 h ab, warnt der Host beim Start und bei jeder
|
||||||
|
Revalidierung. Die verbleibende Frist zeigt **Deployment Center → Lizenzstatus
|
||||||
|
anzeigen**. Falls Predictalytics planmäßig länger offline laufen soll, muss die
|
||||||
|
TTL im WebUI für das Projekt `predictalytics` heraufgesetzt werden.
|
||||||
|
|
||||||
|
### Wann die App sich beendet — und wann nicht
|
||||||
|
|
||||||
|
Maßgeblich ist `LicenseValidationResult.IsTransient`:
|
||||||
|
|
||||||
|
| | Zustände | Reaktion |
|
||||||
|
|---|---|---|
|
||||||
|
| `IsValid` | `valid`, `valid_offline` | weiter |
|
||||||
|
| `IsTransient` | `server_unavailable`, `cache_expired` | **kein Urteil, nur eine gescheiterte Verbindung** — weiterlaufen, beim nächsten Durchlauf erneut versuchen |
|
||||||
|
| sonst | `revoked`, `expired`, `not_found`, `activation_limit`, `suspended`, `clock_rollback` | Meldung und Beenden |
|
||||||
|
|
||||||
|
`cache_expired` beendet die laufende Sitzung also nicht — der **nächste Start**
|
||||||
|
bleibt aber am Lizenzdialog hängen, weil `IsValid` dann falsch ist. Der Host
|
||||||
|
loggt diesen Fall deshalb als Error, nicht bloß als Warnung.
|
||||||
|
|
||||||
|
### Deaktivierung bei PC-Wechsel
|
||||||
|
|
||||||
|
`POST /api/license/v1/deactivate` verlangt den `shared_key` aus der
|
||||||
|
Server-Konfiguration. Der gehört **nicht** in die ausgelieferte Anwendung,
|
||||||
|
deshalb ist die Funktion hier nicht verdrahtet. Übliche Route: im WebUI unter
|
||||||
|
**Lizenzen → Hardware-Liste → „Freigeben"**. Die Hardware-ID zeigt der Host unter
|
||||||
|
**Deployment Center → Lizenzstatus anzeigen**.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 4. Fehler-Stream
|
||||||
|
|
||||||
|
`Services/DcErrorReporter.cs` meldet Laufzeitfehler an
|
||||||
|
`POST /api/errors/v1/report`. Zwei Wege führen dorthin:
|
||||||
|
|
||||||
|
1. **Globale Handler** — `Application.ThreadException` (UI-Thread),
|
||||||
|
`AppDomain.UnhandledException` (Level `fatal`, wird blockierend gesendet, weil
|
||||||
|
der Prozess gleich weg ist) und `TaskScheduler.UnobservedTaskException`.
|
||||||
|
2. **Serilog-Sink** (`Services/DcErrorSink.cs`) — jedes `Log.Error`/`Log.Fatal`,
|
||||||
|
auch aus Worker und Kestrel.
|
||||||
|
|
||||||
|
Lokale Bremse, damit das Rate-Limit (60/min und IP) nicht verbrannt wird:
|
||||||
|
höchstens 20 Meldungen pro Minute, derselbe Fehler höchstens alle 5 Minuten.
|
||||||
|
Serverseitig werden gleiche Fehler ohnehin gruppiert und hochgezählt;
|
||||||
|
betriebsbedingtes Rauschen gehört in die **Ignore-Regeln** des WebUI — ein
|
||||||
|
Treffer zählt weiter, meldet aber nicht.
|
||||||
|
|
||||||
|
> Der Serilog-Filter in `Program.cs` wirft `Duplicate entry`-Ausnahmen schon
|
||||||
|
> vorher weg; die erreichen den Stream also gar nicht.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 5. Updates
|
||||||
|
|
||||||
|
`Services/DcUpdateService.cs` fragt beim Start
|
||||||
|
`GET /api/updateservice/v1/check` ab (ohne Token). Gefunden wird nur — installiert
|
||||||
|
wird nichts von selbst:
|
||||||
|
|
||||||
|
- Kein Update: Info ins Log.
|
||||||
|
- Update verfügbar: Warnung ins Log, Hinweis in der Statusleiste.
|
||||||
|
- **Kritisches** Update: zusätzlich ein Dialog.
|
||||||
|
- Menü **Deployment Center → Nach Updates suchen** prüft jederzeit von Hand.
|
||||||
|
|
||||||
|
Liegt `update-agent.exe` neben der Anwendung, bietet der Dialog an, ihn zu
|
||||||
|
starten; die Anwendung meldet dann vorher `stopped` und beendet sich. Fehlt der
|
||||||
|
Agent, weist der Dialog auf die manuelle Installation hin.
|
||||||
|
|
||||||
|
Seit SDK 2.1 liefert auch der API-Zweig vollständige Release-Daten
|
||||||
|
(Download-Adresse, Prüfsumme, Changelog, Kritikalität) — der Dialog zeigt die
|
||||||
|
Release Notes also auch dann, wenn die statische `latest.json` fehlt.
|
||||||
|
|
||||||
|
### Versionsstand
|
||||||
|
|
||||||
|
`Predictalytics.WinFormsHost.csproj` importiert `Deploymentcenter.BuildInfo.targets`
|
||||||
|
und erzeugt daraus zur Übersetzungszeit `Predictalytics.WinFormsHost.BuildInfo`
|
||||||
|
mit `Version`, `GitCommit`, `GitCommitShort`, `BuildDateUtc`, `Channel` und
|
||||||
|
`Summary`. Quelle ist `<Version>` in derselben csproj — beim Release dort
|
||||||
|
hochziehen und mit
|
||||||
|
|
||||||
|
```
|
||||||
|
pack-and-deploy --project predictalytics --version <x> --channel prod
|
||||||
|
```
|
||||||
|
|
||||||
|
veröffentlichen. Dieselbe Version geht an die Lizenz-Aktivierungsliste, an den
|
||||||
|
Heartbeat und als `build` an den Fehler-Stream; `GitCommitShort` reist im
|
||||||
|
`context` jeder Fehlermeldung mit.

## 1. Watchdog (Dead-Man's-Switch)
|
|
||||||
|
|
||||||
`Services/WatchdogHeartbeatService.cs` sendet alle *n* Sekunden einen
|
|
||||||
`POST /api/heartbeat` an den Watchdog. Bleiben die Heartbeats aus — weil die App
|
|
||||||
abgestürzt ist oder die ganze Maschine weg ist — schlägt der Watchdog Alarm.
|
|
||||||
Beim regulären Schließen geht ein `POST /api/event` mit `kind=stopped_graceful`
|
|
||||||
raus, damit ein geplantes Beenden nicht als Crash alarmiert wird.
|
|
||||||
|
|
||||||
> **Nicht auf `kind=stopping` ändern.** Der Watchdog akzeptiert den Wert im
|
|
||||||
> Router, aber `event_log.kind` ist ein ENUM ohne `stopping`. Der Server setzt
|
|
||||||
> dann zwar noch den Zustand auf `stopped`, scheitert aber am Insert und liefert
|
|
||||||
> HTTP 500 — das Event fehlt in der Historie. Verifiziert am 2026-07-30.
|
|
||||||
|
|
||||||
**Wichtig:** Ein Ausfall des Watchdogs darf Predictalytics nie beeinträchtigen.
|
|
||||||
Alle Aufrufe sind best effort; der erste Fehlschlag wird als Warnung geloggt,
|
|
||||||
Folgefehler nur noch auf Debug-Level (keine Log-Flut).
|
|
||||||
|
|
||||||
### Konfiguration (PropertyGrid im Host, Kategorie „Watchdog")
|
|
||||||
|
|
||||||
| Feld | Default | Bedeutung |
|
|
||||||
|---|---|---|
|
|
||||||
| `Enabled` | `true` | Heartbeats an/aus |
|
|
||||||
| `Server URL` | `https://watchdog.mhdf.de` | Basis-URL |
|
|
||||||
| `API Key` | *(leer)* | `X-Watchdog-Key` — Shared Key **oder** Agent-Token. Ohne Key passiert nichts. |
|
|
||||||
| `Source` | `Predictalytics` | Monitor-Name im Dashboard (Auto-Registrierung beim ersten Beat) |
|
|
||||||
| `Instance` | `default` | falls mehrere Instanzen laufen |
|
|
||||||
| `Interval (Sekunden)` | `60` | Sende-Takt; Alarm nach ca. `Intervall × 1,5 + 30 s` |
|
|
||||||
|
|
||||||
Der Key landet in der `settings.json` neben der Exe (nicht im Git).
|
|
||||||
|
|
||||||
### PolyTrader-Maschine mit überwachen
|
|
||||||
|
|
||||||
Der Heartbeat aus Predictalytics deckt nur *diesen* Prozess ab. Damit auch die
|
|
||||||
Maschine überwacht wird, auf der PolyTrader läuft, gehört dort zusätzlich der
|
|
||||||
OS-Agent hin: `WatchDog\agents\windows\watchdog-agent.ps1` als Scheduled Task
|
|
||||||
(inkl. Shutdown-Hook), bzw. `agents/linux/watchdog-agent.sh` per systemd-Timer.
|
|
||||||

||||||

|
|
||||||
|
|
||||||
## 2. LicenseLabrador (Kopierschutz)
|
|
||||||
|
|
||||||
`Services/LicenseGuard.cs` prüft beim Start, ob eine nutzbare Lizenz vorliegt
|
|
||||||
(`Program.Main` bricht sonst ab, bevor die MainForm überhaupt entsteht).
|
|
||||||
Ohne gültige Lizenz erscheint `Services/LicenseDialog.cs` zur Key-Eingabe.
|
|
||||||
|
|
||||||
Produkt-Slug, Endpoint und der Ed25519-Public-Key sind **bewusst einkompiliert**
|
|
||||||
und nicht konfigurierbar — ein einstellbarer Endpoint würde erlauben, die App auf
|
|
||||||
einen gefälschten Lizenzserver zu zeigen.
|
|
||||||
|
|
||||||
- **Produkt-Slug:** `predictalytics`
|
|
||||||
- **Offline-Gnadenfrist:** 168 h (7 Tage) — danach ist Serverkontakt nötig
|
|
||||||
- **Revalidierung zur Laufzeit:** alle 12 h; bei Widerruf/Ablauf beendet sich die App
|
|
||||||
- **Härtung:** `VerifyChecksum` (HMAC über State + Key + Hardware-ID) gegen Memory-Patches;
|
|
||||||
Nonce-Reflexion und Signaturprüfung übernimmt das SDK
|
|
||||||
|
|
||||||
### Status
|
|
||||||
|
|
||||||
Produkt `predictalytics` und Lizenzschlüssel sind angelegt; die Aktivierung wurde
|
|
||||||
am 2026-07-30 gegen den Produktivserver verifiziert (`Valid`, gültig bis
|
|
||||||
2040-12-31, Checksum-Prüfung bestanden). Der einkompilierte Public Key passt zum
|
|
||||||
`signing.pub` des Servers — sonst käme `TamperSuspected` statt `Valid`.
|
|
||||||
|
|
||||||
Die Aktivierung ist an die Hardware-ID der jeweiligen Maschine gebunden. Auf
|
|
||||||
einem neuen Rechner erscheint einmalig der Dialog; der Cache liegt danach unter
|
|
||||||
`%AppData%\predictalytics\license`.
|
|
||||||
|
|
||||||
### Deaktivierung bei PC-Wechsel
|
|
||||||
|
|
||||||
`LicenseClient.DeactivateAsync()` gibt die Aktivierung wieder frei. Aktuell nicht
|
|
||||||
in der UI verdrahtet — bei Bedarf als Menüpunkt ergänzen.
