'juju status' difficult to read and provides unneccessary information

[Jono Bacon]

From using 'juju status' it provides me with a lot of detail, but most of it I don't care about. I care about the following:

 * Are my machines up.
 * Are my charms connected.
 * Where can access my service online?

To illustrate this I deployed two wordpress charms with mysql. This is what 'juju status' gives me:

jono@forge:~$ juju status
machines:
  "0":
    agent-state: started
    agent-version: 1.10.0
    dns-name: ec2-107-22-102-86.compute-1.amazonaws.com
    instance-id: i-d5db6fbf
    series: precise
  "1":
    agent-state: started
    agent-version: 1.10.0

      wordpress/1:

I just took a few minutes to play with an alternative way of presenting this information based upon the information I really care about (I think all the detail shown above should be accessible with 'juju status -v').

I think this is a better way of displaying it:

jono@forge:~$ juju status

Overview:

   [All services started]

   wordpress/0: ec2-54-226-44-116.compute-1.amazonaws.com
   wordpress/1: ec2-54-226-44-116.compute-1.amazonaws.com
   mysql: ec2-54-226-45-46.compute-1.amazonaws.com

Topology:

   mysql/0 --|-- wordpress/0
             |-- wordpress/1

Machines:

  "0" (i-d5db6fbf) [STARTED]
    Version: 1.10.0
    DNS: ec2-107-22-102-86.compute-1.amazonaws.com
    Series: precise

  "1" (i-74500d1c) [STARTED]
    Version: 1.10.0
    DNS: ec2-54-226-44-116.compute-1.amazonaws.com
    Series: precise

  "2" (i-5a500d32) [STARTED]
    Version: 1.10.0
    DNS: ec2-54-226-45-46.compute-1.amazonaws.com
    Series: precise

  "3" (i-5a500d32) [STARTED]
    Version: 1.10.0
    DNS: ec2-54-226-15-107.compute-1.amazonaws.com
    Series: precise

The 'Overview' section tells me if everything is up and where to access my things. The 'Topology' section makes it clear that everything is connected. The 'Machines' section gives me details about the individual machines, but I re-formatted these to highlight the status (I put all status indications in square brackets in this mock-up).

I would strongly recommend we display this (or another improved) simplified status as the default and show the detail with -v.

Status changed to 'Confirmed' because the bug affects multiple users.

I think we can close this now - juju status --format accepts a number of new output formats (in addition to the default "yaml" and optional "json"). Excerpt from juju status --help:

There are a number of ways to format the status output:

- {short|line|oneline}: List units and their subordinates. For each
           unit, the IP address and agent status are listed.
- summary: Displays the subnet(s) and port(s) the environment utilizes.
           Also displays aggregate information about:
           - MACHINES: total #, and # in each state.
           - UNITS: total #, and # in each state.
           - SERVICES: total #, and # exposed of each service.
- tabular: Displays information in a tabular format in these sections:
           - Machines: ID, STATE, VERSION, DNS, INS-ID, SERIES, HARDWARE
           - Services: NAME, EXPOSED, CHARM
           - Units: ID, STATE, VERSION, MACHINE, PORTS, PUBLIC-ADDRESS
             - Also displays subordinate units.
- yaml (DEFAULT): Displays information on machines, services, and units
                  in the yaml format.
