In ssh, when I run this command
nova diagnostics 2ad0dda0-072d-46c4-8689-3c487a452248
I got all the resources in devstack

How can I get this in devstack user interfaces.
Please help..
Thanks in advance
its not available in openstack icehouse/juno version though it can be edited in juno to retrieve in devstack.
I didn't use openstack Kilo. In juno, if your hypervisor is libvirt, Vsphere or XenAPI then you can retrive this statistics in devstack UI. for this you have to do this:
For Libvirt In this location ceilometer/compute/virt/libvirt/inspector.py, add this:
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})
