ceilometer event-list is empty

Hi guys,

I have installed openstack by devstack. I am getting output for ceilometer meter-list,But when I try to query events using ceilometer event-list,ceilometer returning empty events.

I added
...
[notification]
store_events=True
 ...

in ceilometer.conf and also set the defifnition_cnfg_file ,and i have no problem with meters,But problem with events. I had made changes to the nova,glance and cinder configuration files as specified in the link http://docs.openstack.org/juno/instal... but not getting events.

Please do reply if anyone solved this issue

Thanks and Regards
