ConfigException: No credentials being used on check_resources

[Rodrigo Barbieri]

Deploying openstack-service-checks on focal-yoga, charm revision 16, looking at nagios I get the following alerts:

trying to run those checks from nagios result in error:

cinder services work though:

OK: All cinder services happy

running from openstack-service-checks node:

but sourcing the novarc nagios file works:

root@juju-cf6c78-fy-nagios-11:~# source /var/lib/nagios/nagios.novarc

OK: servers

check_cinder_services.py reads the credentials automatically:

parser.add_argument(
        "--env",
        dest="env",
        default="/var/lib/nagios/nagios.novarc",
        help="Novarc file to use for this check",
    )
