得到了所有的資源，我怎樣才能得到這個devstack用戶界面。

請幫助..

在此先感謝

其在OpenStack的冰窖不可/ JUNO版本，雖然它可以在JUNO編輯在devstack檢索。

我沒有使用openstack Kilo。在juno中，如果您的虛擬機管理程序是libvirt，Vsphere或XenAPI，那麼您可以在devstack UI中檢索此統計信息。爲此，你必須這樣做：

對於Libvirt庫 在這個位置雲高儀/計算/的virt/libvirt的/ inspector.py，補充一點：

from oslo.utils import units 
from ceilometer.compute.pollsters import util 


    def inspect_memory_usage(self, instance, duration=None): 
     instance_name = util.instance_name(instance)  
     domain = self._lookup_by_name(instance_name)  
     state = domain.info()[0]  
     if state == libvirt.VIR_DOMAIN_SHUTOFF: 
      LOG.warn(_('Failed to inspect memory usage of %(instance_name)s, ' 
         'domain is in state of SHUTOFF'),  
        {'instance_name': instance_name}) 
      return 
     try:  
      memory_stats = domain.memoryStats() 
      if (memory_stats and  
        memory_stats.get('available') and 
        memory_stats.get('unused')):  
       memory_used = (memory_stats.get('available') - 
           memory_stats.get('unused')) 
       # Stat provided from libvirt is in KB, converting it to MB.  
       memory_used = memory_used/units.Ki  
       return virt_inspector.MemoryUsageStats(usage=memory_used) 
      else: 
       LOG.warn(_('Failed to inspect memory usage of ' 
          '%(instance_name)s, can not get info from libvirt'), 
         {'instance_name': instance_name}) 
     # memoryStats might launch an exception if the method 
     # is not supported by the underlying hypervisor being 
     # used by libvirt 
     except libvirt.libvirtError as e: 
      LOG.warn(_('Failed to inspect memory usage of %(instance_name)s, ' 
         'can not get info from libvirt: %(error)s'), 
           {'instance_name': instance_name, 'error': e})
