Comment 3 for bug 1853886

The approach described in #1 has been slightly modified. When a Neutron port reports "DOWN", the nagios alert raised is CRITICAL, not warning.

The PR mentioned in #2 is ready for review. As mentioned in my last comment [1], I think the use of python-openstackclient, installed via layer.yaml, will need to be reviewed. The nrpe script(s) are able to use native python libs, but it would break the approach taken until now (use a snap from the snapstore of deployed via Juju resources, in case no Internet access exists).
