Examples with DeviceSystemStats org.onosproject.net.behaviour.DeviceSystemStats used on opensource projects

Example 1 with DeviceSystemStats

use of org.onosproject.net.behaviour.DeviceSystemStats in project onos by opennetworkinglab.

the class PicaOvsdbSystemStatsQuery method getDeviceSystemStats.

/**
 * Get system stats (cpu/mmeory usage) of device.
 *
 * @return deviceSystemStats, system stats (cpu/memory usage) of device if available
 */
@Override
public Optional<DeviceSystemStats> getDeviceSystemStats() {
    Optional<DeviceCpuStats> cpuStats = getCpuUsage();
    Optional<DeviceMemoryStats> memoryStats = getMemoryUsage();
    if (cpuStats.isPresent() && memoryStats.isPresent()) {
        DeviceSystemStats systemStats = new DeviceSystemStats(memoryStats.get(), cpuStats.get());
        return Optional.of(systemStats);
    } else {
        return Optional.empty();
    }
}

Example 2 with DeviceSystemStats

use of org.onosproject.net.behaviour.DeviceSystemStats in project onos by opennetworkinglab.

the class ServerDevicesDiscovery method getDeviceSystemStats.

/**
 * Implements DeviceSystemStatisticsQuery behaviour.
 */
@Override
public Optional<DeviceSystemStats> getDeviceSystemStats() {
    // Retrieve the device ID from the handler
    DeviceId deviceId = getDeviceId();
    checkNotNull(deviceId, MSG_DEVICE_ID_NULL);
    // ....to retrieve monitoring statistics
    MonitoringStatistics monStats = getGlobalMonitoringStatistics(deviceId);
    Optional<DeviceCpuStats> cpuStats = getOverallCpuUsage(monStats);
    Optional<DeviceMemoryStats> memoryStats = getOverallMemoryUsage(monStats);
    if (cpuStats.isPresent() && memoryStats.isPresent()) {
        return Optional.of(new DeviceSystemStats(memoryStats.get(), cpuStats.get()));
    } else {
        return Optional.empty();
    }
