Deploying with Nagios
=====================

The nagios and nrpe charms from the charm store can be added to a deployment
to test the actual nagios checks. After deploying the two charms, add the
relationships between nrpe and the desired component(s) to monitor and then
between nrpe and nagios. First add the extra charms:

.. code-block:: none

   juju deploy nagios
   juju deploy nrpe

The nagios charm is known to fail the install hook due to a missing
'apt-get update'. To resolve this:

.. code-block:: none

   juju run --service nagios "apt-get update"
   juju resolved --retry nagios/0

Use 'juju status' to monitor for a successful nagios deployment. Then
add the relationships:

.. code-block:: none

   juju add-relation nrpe ci-airline-bsb-worker
   juju add-relation nrpe nagios

Now find the nagios password:

.. code-block:: none

   juju ssh nagios/0 sudo cat /var/lib/juju/nagios.passwd

Use 'juju status' to find the public-address of the nagios instance, then
navigate to 'http://<public-address>/nagios3' with a username of 'nagiosadmin'
and the password from above.
