Hi Yurii Prokulevych,

I am using ceilometer- 2.4.0 and i am getting the following error

ceilometerclient.openstack.common.apiclient.exceptions.HttpNotImplemented: Selectable aggregate function mmm is not supported
which is correct i guess.

please correct me if i am wrong

Regards
Sirisha

    return 400 when invalid aggregation function is specified

    When an invalid aggregation function is specified, MongoDB backend
    will raise a 500 KeyError, SQL backend will return a 501 NotImplementedError.
    However, such invalid aggregation functions will not be supported now
    or by schedule. We should return 400 instead.
