https://review.opendev.org/c/openstack/tripleo-heat-templates/+/805559

Merged in wallaby.

Comment 5 Matthias Runge 2021-10-12 16:43:18 UTC

How to test
$ podman inspect collectd

see "CapAdd", there should be

"CapAdd": [
                "CAP_IPC_LOCK"
            ],


Then, add to a deployment yaml file:

CollectdContainerAdditionalCapAdd:
    - "CAP_SYS_RAWIO"

and redeploy. It should get added to collectd Capabilites

That was not possible before this change.

[2022-06-20 10:42:26] plugin_load: plugin "smart" successfully loaded.

No  "CAP_SYS_RAWIO capability is missing" error messages observed.

Comment 9 Leif Madsen 2022-08-29 18:11:54 UTC

I have also verified that the documentation at https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.2/html/operational_measurements/collectd-plugins_assembly under the _collectd::plugin::smart_ section does refer to this capability.
