Example 1 with DeviceCpuStats

use of org.onosproject.net.behaviour.DeviceCpuStats 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
 */

        return Optional.of(systemStats);
    } else {
        return Optional.empty();
    }
}

Example 2 with DeviceCpuStats

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