Juju lint-false positives for nagios

[Michał Ajduk]

Juju-lint reports a false positive issue for nagios.

2019-12-10 09:00:21 [INFO] The following subordinates couldn't be found:
2019-12-10 09:00:21 [ERROR] -> nrpe [nagios]

This means that nagios unit does not have it's subordinate nrpe. Please not that nagios charm does not expose relation of type nrpe-external-master which is for subordinates:

ubuntu@maas001-rack001:~/$ juju add-relation "nagios:nrpe-external-master" "nrpe-container:nrpe-external-master"
ERROR application "nagios" has no "nrpe-external-master" relation

The relation nagios - general-info does not allow setting this.

Hence nagios charm is not ready to have subordinate nrpe checks and this should be excluded from juju-lint checks.

We have a customer who is running the juju-lint as part of verification, and ideally would not like to see this error. So, if we could resolve this, then that would be appreciated

any thoughts on this please?

Please see comments in the MR.

MR has been approved. I think it would also make sense to test this on a real cloud, and update the canonical reference rules in the repository before closing out this bug.
