|

## Процесс планирования мощности
|
||||
|
||||
### 1. Current Capacity Analysis
|
||||
```java
|
||||
// Анализ текущей производительности
|
||||
@Component
|
||||
public class CapacityAnalyzer {
|
||||
private final MeterRegistry meterRegistry;
|
||||
|
||||
public CapacityAnalyzer(MeterRegistry meterRegistry) {
|
||||
this.meterRegistry = meterRegistry;
|
||||
}
|
||||
|
||||
@Scheduled(fixedRate = 60000) // каждую минуту
|
||||
public void analyzeCapacity() {
|
||||
// Анализ CPU
|
||||
double cpuUsage = getCpuUsage();
|
||||
log.info("CPU usage: {}%", cpuUsage * 100);
|
||||
|
||||
// Анализ памяти
|
||||
double memoryUsage = getMemoryUsage();
|
||||
log.info("Memory usage: {}%", memoryUsage * 100);
|
||||
|
||||
// Анализ пропускной способности
|
||||
double throughput = getThroughput();
|
||||
log.info("Throughput: {} RPS", throughput);
|
||||
|
||||
// Анализ задержки
|
||||
double latency = getLatency();
|
||||
log.info("Latency: {} ms", latency);
|
||||
|
||||
// Предупреждения
|
||||
if (cpuUsage > 0.8) {
|
||||
log.warn("High CPU usage detected!");
|
||||
}
|
||||
if (memoryUsage > 0.8) {
|
||||
log.warn("High memory usage detected!");
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Load Forecasting
|
||||
```java
|
||||
// Прогнозирование нагрузки
|
||||
@Service
|
||||
public class LoadForecaster {
|
||||
@Autowired
|
||||
private MetricsRepository metricsRepository;
|
||||
|
||||
public LoadForecast forecastLoad(int days) {
|
||||
// Получаем исторические данные
|
||||
List<MetricData> historicalData = metricsRepository
|
||||
.findByDateRange(LocalDateTime.now().minusDays(30), LocalDateTime.now());
|
||||
|
||||
// Анализируем тренды
|
||||
double growthRate = calculateGrowthRate(historicalData);
|
||||
|
||||
// Прогнозируем нагрузку
|
||||
double currentLoad = getCurrentLoad();
|
||||
double forecastedLoad = currentLoad * Math.pow(1 + growthRate, days);
|
||||
|
||||
return new LoadForecast(forecastedLoad, growthRate, days);
|
||||
}
|
||||
|
||||
private double calculateGrowthRate(List<MetricData> data) {
|
||||
// Простой расчет темпа роста
|
||||
if (data.size() < 2) return 0.0;
|
||||
|
||||
double firstValue = data.get(0).getValue();
|
||||
double lastValue = data.get(data.size() - 1).getValue();
|
||||
|
||||
return (lastValue - firstValue) / firstValue / data.size();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Resource Planning
|
||||
```yaml
|
||||
# Планирование ресурсов
|
||||
capacity_planning:
|
||||
current_capacity:
|
||||
cpu: "4 cores"
|
||||
memory: "8 GB"
|
||||
storage: "100 GB"
|
||||
network: "1 Gbps"
|
||||
|
||||
forecasted_load:
|
||||
peak_rps: 1000
|
||||
average_rps: 500
|
||||
growth_rate: "20% per month"
|
||||
|
||||
resource_requirements:
|
||||
cpu:
|
||||
current: "80% utilization"
|
||||
target: "70% utilization"
|
||||
required: "6 cores"
|
||||
|
||||
memory:
|
||||
current: "75% utilization"
|
||||
target: "65% utilization"
|
||||
required: "12 GB"
|
||||
|
||||
storage:
|
||||
current: "60% utilization"
|
||||
target: "50% utilization"
|
||||
required: "150 GB"
|
||||
```
