Hello Eoghan,
Thanks for the update.
1.Openstack Document link : http://docs.openstack.org/trunk/install-guide/install/apt/content/ceilometer-controller-install.html
2. ceilometer packages installed : apt-get install ceilometer-api ceilometer-collector ceilometer-agent-central ceilometer-agent-notification ceilometer-alarm-evaluator ceilometer-alarm-notifier python-ceilometerclient
I have installed 'python-pymongo' as per your suggestion and commented ceilometer.sqlite db usage in /etc/ceilometer/ceilometer.conf and pointed it to use mongodb database.
Now I can see ceilometer-api is running and listening on 8777.
Thanks again for your solution .
Regards,
Malleshi CN

Which document exactly?

I suspect install this mongodb meta-package caused mongodb-clients to installed.
Whereas the actual client-side dependency that ceilometer has is on python-pymongo, as opposed mongodb-clients.
This can be clearly seen from:
http://packages.ubuntu.com/trusty/python-ceilometer
[...]
> If I won't delete sqlite db, all ceilometer data will be stored in sqlitedb. If I am wrong correct me , because I can see the size of the file increasing .
Deleting is not the key here, rather stopping ceilometer using sql-a to store data is what you need:
1. Ensure the connection_url in the ceilometer.conf is using a
mongodb URL[1]
2. Ensure the python-pymongo package is installed
3. Restart the services that use the metering store (ceilometer-api,
collector and notification-agent)
Cheers,
Eoghan
