'ceilometer.storage' driver found

Asked by Riki Arslan on 2012-10-20


I am trying to run ceilometer-collector on stable/folsom. However, I am getting the following error. I would appreciate your help on this:

  File "/usr/local/lib/python2.7/dist-packages/stevedore-0.4-py2.7.egg/stevedore/driver.py", line 34, in __init__
    raise RuntimeError('No %r driver found, looking for %r' % (namespace, name))

It looks like it cannot find or import the database driver to talk to MongoDB. Did you install the dependencies for using Mongo?

How did you install ceilometer?

I am facing the same error. I've installed devstack without installing ceilometer and latter, installed ceilometer following the documentation: first installed mondgodb and then ceilometer.

Hello Doug,

I have installed ceilometer through these steps:
$ cd /home/user
$ git clone https://github.com/stackforge/ceilometer.git
$ cd ceilometer
$ sudo python setup.py install
$ grep -v format_string /etc/nova/nova.conf > /etc/ceilometer-collector.conf
$ ./bin/ceilometer-collector

I have also installed MongoDB through these default steps:

I can access MongoDB both locally and remotely. However, as you have stated, ceilometer can not find the default MongoDB instance:

               help='Database connection string',

Does ceilometer require any additional dependencies that are not listed? Should I install an additional driver?

Doug Hellmann (doug-hellmann) said : #4

It appears we are missing a step from our installation instructions.

Ceilometer does not set a dependency on any database drivers because our intent is to allow you to use any database backend. The driver for Mongo can be installed with:

$ sudo pip install pymongo==2.2.1

There may also be a system package for the driver, I'm not sure.

Year later I'm getting the same problem with latest devstack. pymongo dependency is installed.
