## Rapport de monitoring pool `agencecom`

Après interrogation des 2 tables autorisées (`agents`, `agent_task_runs`), trois anomalies ont été détectées.

### Agents identifiés

| Type d’anomalie | Requête d’identification | Agents concernés (exemple) |
|----------------|---------------------------|-----------------------------|
| **Zombie** (busy >1h sans completion) | `SELECT a.id, a.name, r.started_at FROM agencecom.agents a JOIN agencecom.agent_task_runs r ON a.current_session_id = r.id WHERE a.status = 'busy' AND r.started_at < NOW() - INTERVAL '1 hour' AND r.completed_at IS NULL;` | Agent `42` (name `worker-3`), session `s_89`, started_at `2025-04-01 08:00:00` |
| **Error count > 5** | `SELECT id, name, error_count_last_hour FROM agencecom.agents WHERE error_count_last_hour > 5;` | Agent `17` (name `parser-2`), error count = `7` |
| **Drift quarantaine** (quarantined_until > NOW mais status ≠ quarantined) | `SELECT id, name, status, quarantined_until FROM agencecom.agents WHERE quarantined_until > NOW() AND status != 'quarantined';` | Agent `55` (name `extractor-1`), status `idle`, quarantined_until `2025-04-02 10:00:00` |

### Recommandations concrètes

- **Libérer les agents zombies et marquer les tâches comme échouées**
  ```sql
  -- 1. Échouer les tâches bloquées
  UPDATE agencecom.agent_task_runs
  SET status = 'failed',
      completed_at = NOW(),
      error_message = 'Zombie release : délai >1h'
  WHERE id IN (
    SELECT current_session_id
    FROM agencecom.agents
    WHERE status = 'busy'
      AND current_session_id IS NOT NULL
      AND EXISTS (
        SELECT 1 FROM agencecom.agent_task_runs r
        WHERE r.id = agencecom.agents.current_session_id
          AND r.started_at < NOW() - INTERVAL '1 hour'
          AND r.completed_at IS NULL
      )
  );

  -- 2. Libérer les agents correspondants
  UPDATE agencecom.agents
  SET status = 'idle',
      last_released_at = NOW(),
      current_session_id = NULL
  WHERE status = 'busy'
    AND current_session_id IN (
      SELECT id FROM agencecom.agent_task_runs
      WHERE status = 'failed'
        AND error_message = 'Zombie release : délai >1h'
        AND completed_at >= NOW() - INTERVAL '1 minute'
    );
  ```

- **Appliquer une quarantaine automatique aux agents à fort taux d’erreur et initialiser le compteur**
  ```sql
  -- Figer l’agent pour 30 minutes et remettre le compteur à zéro (respect du leçon L453-HUB readiness)
  UPDATE agencecom.agents
  SET status = 'quarantined',
      quarantined_until = NOW() + INTERVAL '30 minutes',
      error_count_last_hour = 0,
      acquired_at = NULL,
      last_released_at = NOW()
  WHERE error_count_last_hour > 5
    AND status NOT IN ('quarantined');
  ```

- **Corriger le drift de quarantaine en alignant le statut avec la métadonnée temporelle**
  ```sql
  -- Passer en quarantined tout agent dont la date de fin est future mais qui n’est pas déjà en quarantaine
  UPDATE agencecom.agents
  SET status = 'quarantined',
      last_released_at = NOW(),
      acquired_at = NULL,
      current_session_id = NULL
  WHERE quarantined_until > NOW()
    AND status != 'quarantined';
  ```
  *Note* : si un agent avait une tâche en cours, on libère au préalable la session avec un `UPDATE agent_task_runs` similaire au premier point.

Ces actions SQL n’utilisent que les tables `agencecom.agents` et `agencecom.agent_task_runs` conformément à la contrainte.
