# Plan: Umbrales de notificación por servidor
## Archivos a modificar/crear
### 1. `database/migrations/012_server_thresholds.sql` — CREAR
```sql
ALTER TABLE `servers`
ADD COLUMN `threshold_cpu_warning` DECIMAL(5,2) DEFAULT 80.00 AFTER `agent_last_seen_at`,
ADD COLUMN `threshold_cpu_critical` DECIMAL(5,2) DEFAULT 95.00 AFTER `threshold_cpu_warning`,
ADD COLUMN `threshold_ram_warning` DECIMAL(5,2) DEFAULT 80.00 AFTER `threshold_cpu_critical`,
ADD COLUMN `threshold_ram_critical` DECIMAL(5,2) DEFAULT 95.00 AFTER `threshold_ram_warning`,
ADD COLUMN `threshold_disk_warning` DECIMAL(5,2) DEFAULT 85.00 AFTER `threshold_disk_warning`,
ADD COLUMN `threshold_disk_critical` DECIMAL(5,2) DEFAULT 95.00 AFTER `threshold_disk_critical`;
```
### 2. `src/Core/Database.php` — MODIFICAR
Agregar método `fetchCol()` después de `fetchAll()`:
```php
public function fetchCol(string $sql, array $params = []): array
{
return $this->query($sql, $params)->fetchAll(\PDO::FETCH_COLUMN);
}
```
### 3. `src/Models/Server.php` — MODIFICAR
Agregar método `getAccessibleUserIds()` antes de `findByAgentKey()`:
```php
public function getAccessibleUserIds(int $serverId): array
{
$direct = $this->db->fetchCol(
'SELECT user_id FROM server_user WHERE server_id = ? AND status = \'active\'',
[$serverId]
);
$team = $this->db->fetchCol(
'SELECT DISTINCT tu.user_id FROM team_user tu
JOIN team_server ts ON tu.team_id = ts.team_id
WHERE ts.server_id = ? AND tu.status = \'active\' AND ts.status = \'active\'',
[$serverId]
);
$owner = $this->db->fetchCol(
'SELECT created_by FROM servers WHERE id = ? AND status = \'active\'',
[$serverId]
);
return array_unique(array_merge($direct, $team, $owner));
}
```
### 4. `routes/web.php` — MODIFICAR
Agregar después de línea 67 (`/servers/:id/metrics`):
```php
$router->post('/servers/:id/thresholds', [ServerController::class, 'saveThresholds'], [AuthMiddleware::class, CSRFMiddleware::class]);
```
### 5. `src/Controllers/ServerController.php` — MODIFICAR
Agregar en `use` imports (si no está ya) + nuevo método después de `metrics()`:
```php
public function saveThresholds(int $id): void
{
$server = $this->requireServerAccess($id, 'manager');
$role = $this->serverModel->getUserRole($id, (int) Session::get('user_id'));
if ($role !== 'owner') {
$this->view->json(['success' => false, 'error' => 'Only the server owner can modify notification thresholds.'], 403);
}
$fields = ['cpu_warning', 'cpu_critical', 'ram_warning', 'ram_critical', 'disk_warning', 'disk_critical'];
$data = [];
foreach ($fields as $f) {
$key = 'threshold_' . $f;
$data[$key] = isset($_POST[$f]) ? max(0, min(100, (float) $_POST[$f])) : null;
}
$this->serverModel->update($id, $data);
$this->auditService->log('thresholds_updated', 'server', $id, $data);
$this->view->json(['success' => true, 'message' => 'Notification thresholds updated.']);
}
```
### 6. `src/Controllers/ApiController.php` — MODIFICAR
En `pushMetrics()`, después de `updateAgentLastSeen()` (línea 435) y antes de `$this->view->json(['success' => true])` (línea 437):
```php
// --- Verificar umbrales de notificación ---
$checks = [
'cpu' => ['val' => $cpu, 'warn' => $server['threshold_cpu_warning'], 'crit' => $server['threshold_cpu_critical']],
'ram' => ['val' => $ram, 'warn' => $server['threshold_ram_warning'], 'crit' => $server['threshold_ram_critical']],
'disk' => ['val' => $disk, 'warn' => $server['threshold_disk_warning'], 'crit' => $server['threshold_disk_critical']],
];
$breaches = [];
foreach ($checks as $metric => $c) {
if ($c['crit'] !== null && $c['val'] >= (float) $c['crit']) {
$breaches[] = ['metric' => $metric, 'level' => 'critical', 'current' => $c['val'], 'threshold' => $c['crit']];
} elseif ($c['warn'] !== null && $c['val'] >= (float) $c['warn']) {
$breaches[] = ['metric' => $metric, 'level' => 'warning', 'current' => $c['val'], 'threshold' => $c['warn']];
}
}
if (!empty($breaches)) {
$userIds = $serverModel->getAccessibleUserIds((int) $server['id']);
$notificationModel = new \ServerManager\Models\Notification();
foreach ($breaches as $b) {
$title = strtoupper($b['metric']) . " {$b['level']} on {$server['name']}";
$message = "{$server['name']}: {$b['metric']} at {$b['current']}% ({$b['level']} threshold: {$b['threshold']}%)";
foreach ($userIds as $uid) {
$notificationModel->create([
'user_id' => (int) $uid,
'title' => $title,
'message' => $message,
'type' => $b['level'],
]);
}
}
}
```
Agregar import de Notification en los `use` del ApiController (si no está):
```php
use ServerManager\Models\Notification;
```
### 7. `views/servers/show.php` — MODIFICAR
**a) Botón en Management Actions** (después de línea 272, antes de `<?php endif; ?>`):
```php
<?php if ($server_role === 'owner'): ?>
<button class="action-card" onclick="showThresholdModal()">
<i class="fas fa-bell"></i>
<span>Notification Thresholds</span>
</button>
<?php endif; ?>
```
**b) Modal** (después del `#agentConfirmModal`, antes de `<form id="csrfForm">`):
```php
<div id="thresholdModal" class="modal">
<div class="modal-dialog">
<div class="modal-header">
<h3><i class="fas fa-bell"></i> Notification Thresholds</h3>
<button type="button" class="modal-close" onclick="closeThresholdModal()">&times;</button>
</div>
<div class="modal-body">
<p class="text-muted" style="margin-bottom:20px">
Notifications are sent to all users with access to this server when the agent reports values
exceeding these thresholds. Only the server owner can modify them.
</p>
<form id="thresholdForm" onsubmit="return false">
<div class="table-responsive">
<table class="table">
<thead>
<tr>
<th>Resource</th>
<th>Warning (%)</th>
<th>Critical (%)</th>
</tr>
</thead>
<tbody>
<?php foreach (['cpu' => 'CPU', 'ram' => 'RAM', 'disk' => 'Disk'] as $key => $label): ?>
<tr>
<td><strong><?= $label ?></strong></td>
<td>
<input type="number" name="<?= $key ?>_warning"
value="<?= htmlspecialchars((string)($server["threshold_{$key}_warning"] ?? 80)) ?>"
min="0" max="100" step="0.01" class="form-control" style="width:120px">
</td>
<td>
<input type="number" name="<?= $key ?>_critical"
value="<?= htmlspecialchars((string)($server["threshold_{$key}_critical"] ?? 95)) ?>"
min="0" max="100" step="0.01" class="form-control" style="width:120px">
</td>
</tr>
<?php endforeach; ?>
</tbody>
</table>
</div>
</form>
</div>
<div class="modal-footer">
<button class="btn btn-primary" onclick="saveThresholds()"><i class="fas fa-save"></i> Save</button>
<button class="btn btn-secondary" onclick="closeThresholdModal()">Cancel</button>
</div>
</div>
</div>
```
**c) JavaScript** (al final del bloque `<script>`, antes de `</script>`):
```javascript
function showThresholdModal() {
document.getElementById('thresholdModal').style.display = 'flex';
document.getElementById('thresholdModal').onclick = function(e) {
if (e.target === this) closeThresholdModal();
};
}
function closeThresholdModal() {
document.getElementById('thresholdModal').style.display = 'none';
}
function saveThresholds() {
const form = document.getElementById('thresholdForm');
const data = new URLSearchParams(new FormData(form));
data.append('_csrf_token', getCsrfToken());
document.querySelector('#thresholdModal .btn-primary').disabled = true;
fetch('/servers/<?= $server['id'] ?>/thresholds', {
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'X-CSRF-Token': getCsrfToken(),
},
body: data.toString(),
})
.then(r => r.json())
.then(d => {
showToast(d.success ? 'success' : 'error', d.message ?? d.error);
if (d.success) closeThresholdModal();
})
.catch(e => showToast('error', 'Request failed: ' + e.message))
.finally(() => {
document.querySelector('#thresholdModal .btn-primary').disabled = false;
});
}
```
### 8. Ejecutar migración
```bash
mysql -u root -p"servermanager2024" servermanager < /var/www/servermanager/database/migrations/012_server_thresholds.sql
```
### 9. Commit y push
```bash
git add -A && git commit -m "feat: per-server notification thresholds with alert on agent metrics push" && git push origin feat/fcm-apk-v1.8.2
```
## Variables de umbral en la vista
Las columnas nuevas (`threshold_cpu_warning`, etc.) viajan automáticamente en `$server` porque `findById()` hace `SELECT *`. No requiere cambios en `ServerController::show()`.
