Example 1 with DeviceMemoryStats

use of org.onosproject.net.behaviour.DeviceMemoryStats 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

    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 DeviceMemoryStats

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

the class PicaOvsdbClient method getDeviceMemoryUsage.

/**
 * Get memory usage of pica device.
 *
 * @return memoryStats, memory usage statistics if present
 */
public Optional<DeviceMemoryStats> getDeviceMemoryUsage() {
    Optional<Object> deviceMemoryDataObject = ovsdbClientService.getFirstRow(SWINVENTORY_DBNAME, OvsdbTable.CPUMEMORYDATA);

        return Optional.empty();
    }
    CpuMemoryData deviceMemoryData = (CpuMemoryData) deviceMemoryDataObject.get();
    long totalMem = deviceMemoryData.getTotalMemoryStats();

    long freeMem = deviceMemoryData.getFreeMemoryStats();
    DeviceMemoryStats deviceMemoryStats = new DeviceMemoryStats();
    deviceMemoryStats.setFree(freeMem);
