wrong key "router.interface" reported by ceilometer log

[Li Ma]

In my testbed, ceilometer throws an exception which is caused by the wrong key format of neutron:

2014-04-01 10:52:39.135 6104 ERROR notification [-] Insert msg to Mongodb occured error:Traceback (most recent call last):
  File "/usr/lib/python2.6/site-packages/ceilometer/billing/backend.py", line 74, in insert_data

    continue_on_error, self.__uuid_subtype), safe)
InvalidDocument: key 'router.interface' must not contain '.'

It seems that mongodb doesn't support "." in key.

The workaround is to change "." with "_" in l3_db.py.

    Wrong key router.interface reported by ceilometer

    Ceilometer with MongoDB doesn't accept the key with dot.

    The dot in 'router.interface' should be replaced with '_',
    which is also the standard implementation of other keys in neutron.
