Description of problem: When executing `openstack metric status`, "500 Internal Server Error" occurs. Version-Release number of selected component (if applicable): How reproducible: 100% Steps to Reproduce: 1. Execute command: `openstack metric status` Actual results: "500 Internal Server Error" occurs. Expected results: No error occurs. Additional info: It seems this is the same issue of this. https://bugs.launchpad.net/charm-gnocchi/+bug/1789947 And this should be fixed with this commit in the upstream. https://github.com/gnocchixyz/gnocchi/commit/7a3ddc4ceb64bf648a5f383814632f72b8700a8f
The reason why this is happening that some of the keys of pecan processed object contains bytes keys instead of string. For example: {'storage': {'summary': {'metrics': 0, 'measures': 0}}, 'metricd': {'processors': {b'controller-0.1.bb4bb372-f148-4320-8ad0-31314d26909e', b'controller-1.0.e9852552-9ada-4eb9-a625-3df110e2d38e', b'controller-2.0.3099a52a-18eb-4989-b239-9e69aabcc70c', b'controller-1.1.a55b8603-281d-4afd-8ac4-a575db1ba0a1', b'controller-0.0.5799e281-63b6-48c2-9a0a-86d0ca8400ab', b'controller-2.1.4789b143-337b-49ef-b0e1-6b697c8dff96'}, 'statistics': {b'controller-0.1.bb4bb372-f148-4320-8ad0-31314d26909e': {}, b'controller-1.0.e9852552-9ada-4eb9-a625-3df110e2d38e': {}, b'controller-2.0.3099a52a-18eb-4989-b239-9e69aabcc70c': {}, b'controller-1.1.a55b8603-281d-4afd-8ac4-a575db1ba0a1': {}, b'controller-0.0.5799e281-63b6-48c2-9a0a-86d0ca8400ab': {}, b'controller-2.1.4789b143-337b-49ef-b0e1-6b697c8dff96': {}}}} We will need to either find out how to avoid using bytes as object keys or teach pecan how to convert keys to string.
