Colelctd Sensubility doesn't work on OSP17.1 and RHEL8.

latest collectd is collectd-5.12.0-10.el8ost

This scenario ma only happen after FFU in Mixed RHEL environment when compute node(s) are RHEL8. Clean OSP17.1 this scenario won't happen. 


The error that I get in sensubility.log

    if len(item['healthy']) > 0 and item['status'] != 'stopped':
TypeError: object of type 'NoneType' has no len()

The problem is that healthcheck script is using podman inspect <container-name> command, which apparently changed output.


Workaround:
-----------

To change /var/lib/container-config-scripts/collectd_check_health.py on line 26 s/“healthy: .State.Health.Status}“/ “healthy: .State.Healthcheck.Status}“/
