## Usage Examples

### Monitor Batch Performance

```javascript
async function monitorBatchPerformance() {
  const response = await fetch("/api/admin/batch-monitoring?timeRange=24h");
  const data = await response.json();

  const performance = data.data.performance;

  // Check if performance is within acceptable ranges
  if (performance.efficiency.errorRate > 10) {
    console.warn("High error rate detected:", performance.efficiency.errorRate + "%");

    // Get failed jobs for analysis
    const failedJobs = await fetch("/api/admin/batch-monitoring?status=failed");
    const failures = await failedJobs.json();

    // Analyze common failure patterns
    const errorSummary = failures.data.jobs.reduce((acc, job) => {
      job.errorSummary?.forEach((error) => {
        acc[error.error] = (acc[error.error] || 0) + error.count;
      });
      return acc;
    }, {});

    console.log("Error patterns:", errorSummary);
  }
}
```

### Cost Savings Analysis

```javascript
async function analyzeCostSavings() {
  const response = await fetch("/api/admin/batch-monitoring?timeRange=30d&includeDetails=true");
  const data = await response.json();

  const savings = data.data.summary.costSavings;

  return {
    currentSavings: savings.currentPeriod,
    projectedAnnual: savings.projectedMonthly * 12,
    savingsRate: savings.savingsPercentage,
    totalProcessed: data.data.summary.processedRequests,
    averageCostPerRequest: savings.currentPeriod / data.data.summary.processedRequests,
  };
}
```

### Retry Failed Jobs

```javascript
async function retryFailedJobs() {
  // Get failed jobs
  const response = await fetch("/api/admin/batch-monitoring?status=failed");
  const data = await response.json();

  const retryableJobs = data.data.jobs.filter((job) => {
    // Only retry jobs that failed due to temporary issues
    const hasRetryableErrors = job.errorSummary?.some((error) =>
      ["rate_limit_exceeded", "temporary_error", "timeout"].includes(error.error)
    );
    return hasRetryableErrors;
  });

  // Retry jobs individually
  for (const job of retryableJobs) {
    try {
      await fetch(`/api/admin/batch-monitoring/${job.id}/retry`, {
        method: "POST",
      });
      console.log(`Retried job ${job.id}`);
    } catch (error) {
      console.error(`Failed to retry job ${job.id}:`, error);
    }
  }
}
```

### Real-time Dashboard Updates

```javascript
function useRealtimeBatchMonitoring() {
  const [data, setData] = useState(null);
  const [isLoading, setIsLoading] = useState(true);

  useEffect(() => {
    const fetchData = async () => {
      try {
        const response = await fetch("/api/admin/batch-monitoring?timeRange=1h");
        const result = await response.json();
        setData(result.data);
      } catch (error) {
        console.error("Failed to fetch batch monitoring data:", error);
      } finally {
        setIsLoading(false);
      }
    };

    // Initial fetch
    fetchData();

    // Update every 30 seconds
    const interval = setInterval(fetchData, 30000);

    return () => clearInterval(interval);
  }, []);

  return { data, isLoading };
}
```

## Configuration

### Batch Processing Settings

Configure batch processing parameters in environment variables:

```bash
# Batch Processing Configuration
BATCH_PROCESSING_ENABLED="true"
BATCH_CREATE_INTERVAL="*/5 * * * *"          # Create batches every 5 minutes
BATCH_STATUS_CHECK_INTERVAL="*/2 * * * *"    # Check status every 2 minutes
BATCH_RESULT_PROCESSING_INTERVAL="*/1 * * * *" # Process results every minute

# Batch Size and Limits
BATCH_MAX_REQUESTS="1000"                     # Maximum requests per batch
BATCH_TIMEOUT_HOURS="24"                      # Batch timeout in hours
BATCH_MIN_SIZE="10"                           # Minimum batch size

# Monitoring Configuration
BATCH_MONITORING_RETENTION_DAYS="30"          # How long to keep monitoring data
BATCH_ALERT_THRESHOLD_ERROR_RATE="10"         # Alert if error rate exceeds 10%
BATCH_ALERT_THRESHOLD_PROCESSING_TIME="3600"  # Alert if processing takes >1 hour
```

### Dashboard Refresh Settings

```javascript
// Configure dashboard update intervals
const DASHBOARD_CONFIG = {
  refreshInterval: 30000, // 30 seconds
  alertRefreshInterval: 10000, // 10 seconds for alerts
  detailRefreshInterval: 60000, // 1 minute for detailed views
  maxRetries: 3, // Maximum retry attempts
  retryDelay: 5000, // Delay between retries
};
```

## Alerts and Notifications

### Automated Alerts

The system automatically generates alerts for:

```javascript
const alertConditions = {
  highErrorRate: {
    threshold: 10, // Error rate > 10%
    severity: "high",
    notification: "immediate",
  },
  longProcessingTime: {
    threshold: 3600000, // > 1 hour
    severity: "medium",
    notification: "hourly",
  },
  lowThroughput: {
    threshold: 0.5, // < 0.5 jobs per hour
    severity: "medium",
    notification: "daily",
  },
  batchFailure: {
    threshold: 1, // Any complete batch failure
    severity: "critical",
    notification: "immediate",
  },
};
```

### Custom Alert Configuration

```javascript
// Configure custom alerts through the admin interface
async function configureAlerts(alertConfig) {
  const response = await fetch("/api/admin/batch-monitoring/alerts", {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({
      errorRateThreshold: alertConfig.errorRate,
      processingTimeThreshold: alertConfig.processingTime,
      notificationChannels: alertConfig.channels,
      alertSuppression: alertConfig.suppression,
    }),
  });

  return response.json();
}
```

## Troubleshooting

### Common Issues

#### High Error Rates

```javascript
// Investigate high error rates
async function investigateErrors() {
  const response = await fetch("/api/admin/batch-monitoring?status=failed&includeDetails=true");
  const data = await response.json();

  // Group errors by type
  const errorAnalysis = data.data.jobs.reduce((acc, job) => {
    job.errorSummary?.forEach((error) => {
      if (!acc[error.error]) {
        acc[error.error] = { count: 0, jobs: [] };
      }
      acc[error.error].count += error.count;
      acc[error.error].jobs.push(job.id);
    });
    return acc;
  }, {});

  console.log("Error analysis:", errorAnalysis);
  return errorAnalysis;
}
```

#### Slow Processing

```javascript
// Analyze processing bottlenecks
async function analyzePerformance() {
  const response = await fetch("/api/admin/batch-monitoring?timeRange=24h&includeDetails=true");
  const data = await response.json();

  const slowJobs = data.data.jobs
    .filter((job) => job.processingTimeMs > 3600000) // > 1 hour
    .sort((a, b) => b.processingTimeMs - a.processingTimeMs);

  console.log("Slowest jobs:", slowJobs.slice(0, 5));

  // Analyze patterns
  const avgByType = slowJobs.reduce((acc, job) => {
    if (!acc[job.jobType]) {
      acc[job.jobType] = { total: 0, count: 0 };
    }
    acc[job.jobType].total += job.processingTimeMs;
    acc[job.jobType].count++;
    return acc;
  }, {});

  Object.keys(avgByType).forEach((type) => {
    avgByType[type].average = avgByType[type].total / avgByType[type].count;
  });

  return avgByType;
}
```

### Performance Optimization

#### Batch Size Optimization

```javascript
// Analyze optimal batch sizes
async function optimizeBatchSizes() {
  const response = await fetch("/api/admin/batch-monitoring?timeRange=7d&includeDetails=true");
  const data = await response.json();

  // Group by batch size ranges
  const sizePerformance = data.data.jobs.reduce((acc, job) => {
    const sizeRange = Math.floor(job.requestCount / 50) * 50; // Group by 50s
    if (!acc[sizeRange]) {
      acc[sizeRange] = {
        jobs: 0,
        totalTime: 0,
        totalRequests: 0,
        successRate: 0,
      };
    }

    acc[sizeRange].jobs++;
    acc[sizeRange].totalTime += job.processingTimeMs;
    acc[sizeRange].totalRequests += job.requestCount;
    acc[sizeRange].successRate += job.completedCount / job.requestCount;

    return acc;
  }, {});

  // Calculate averages
  Object.keys(sizePerformance).forEach((range) => {
    const perf = sizePerformance[range];
    perf.avgTimePerRequest = perf.totalTime / perf.totalRequests;
    perf.avgSuccessRate = perf.successRate / perf.jobs;
  });

  return sizePerformance;
}
```

## Integration with Existing Systems

### Security Audit Integration

All batch monitoring activities are logged through the security audit system:

```javascript
// Automatic audit logging for monitoring activities
await securityAuditLogger.logPlatformAdmin(
  "batch_monitoring_access",
  AuditOutcome.SUCCESS,
  context,
  "Admin accessed batch monitoring dashboard"
);
```

### Rate Limiting Integration

Monitoring API endpoints use the existing rate limiting system:

```javascript
// Protected by admin rate limiting
const rateLimitResult = await rateLimiter.check(
  `admin-batch-monitoring:${userId}`,
  60, // 60 requests
  60 * 1000 // per minute
);
```
