If a tenant starts goes above a certain threshold of IOPS, flag this up to the admin within a short period of time so they can take action.
Release version is 9 ?
Re-reading the question and my comment, I actually think this is possible with this: $ aodh alarm create --type gnocchi_aggregation_by_resources_threshold --name iops-test-1 --metric disk.read.requests.rate --threshold 42000 --aggregation-method sum --resource-type instance --query '{"=": {"project_id": "cdf80e24-0644-4869-aab2-189d444ea906"}}' +---------------------------+---------------------------------------------------------------+ | Field | Value | +---------------------------+---------------------------------------------------------------+ | aggregation_method | sum | | alarm_actions | [] | | alarm_id | 687f44e3-8db7-4181-8f51-80267ca6492c | | comparison_operator | eq | | description | gnocchi_aggregation_by_resources_threshold alarm rule | | enabled | True | | evaluation_periods | 1 | | granularity | 60 | | insufficient_data_actions | [] | | metric | disk.read.requests.rate | | name | iops-test-1 | | ok_actions | [] | | project_id | admin | | query | {"=": {"project_id": "cdf80e24-0644-4869-aab2-189d444ea906"}} | | repeat_actions | False | | resource_type | instance | | severity | low | | state | insufficient data | | state_timestamp | 2016-05-17T13:07:47.691720 | | threshold | 42000.0 | | time_constraints | [] | | timestamp | 2016-05-17T13:07:47.691720 | | type | gnocchi_aggregation_by_resources_threshold | | user_id | admin | +---------------------------+---------------------------------------------------------------+ This will create a new alarm that will analyse the sum() of all read requests for all instance of a particular tenant (the query can be restrained even more with the --query parameter). That should cover the initial request.
