Ansible-Uchiwa

Ansible role for installing and configuring Uchiwa, the open-source sensu dashboard.

Requirements

This role doesn't have any hard dependencies on other roles. Uchiwa can run on a standalone, vanilla box. However, you may want to connect Uchiwa to sensu-api in order to display clients and events.

You can install Sensu and RabbitMQ on the same node. The following Ansible roles may help:

• ansible-playbook-rabbitmq
• ansible-playbook-sensu

Supported systems

Currently Debian-like and RedHat-like operating systems are supported. This includes the popular Ubuntu and CentOS.

This role is tested on ubuntu/precise64 and centos/6.5 OSes. For more information, check out the vagrant folder included in this project.

Installation

You can use ansible-galaxy:

$ ansible-galaxy install queeno.ansible-uchiwa

Footnotes

¹ http://repos.sensuapp.org/apt/pubkey.gpg

² sensu_yum_repo could be either sensu (installs the stable YUM repo) or sensu-unstable (installs the unstable YUM repo). The repo configuration is in files\*sensu_yum_repo*.repo.

³ version takes the following values:

• latest: Ensures the uchiwa latest version is always installed.
• installed: Installs the uchiwa latest version without updating it.
• *version number*: Explicitly specify a version number to pin uchiwa to a specific version.

⁴ sensu_api_endpoints identifies the sensu API endpoints, so uchiwa can connect to them.

You don't need to overwrite all the hash keys in the array. If you don't pass a hash key, the respective default will be used.

Name	Type	Description	Default
name	String	The name of the sensu API endpoint	'sensu'
host	String	The IP address or name of the sensu API endpoint	'127.0.0.1'
ssl	Boolean	Determines whether or not the sensu API endpoint requires SSL authentication	False

user	String	The username of the sensu API endpoint	'' (empty for none)
pass	String	The password of the sensu API endpoint	'' (empty for none)
path	String	The path to the sensu API endpoint	'' (empty for none)
timeout	Integer	Timeout of the sensu API endpoint in seconds	5

⁵ users specifies a list of user credentials to access the uchiwa dashboard. This feature is available from uchiwa 0.10.0. users has precedence over user. If left empty or omitted the user and password values will be used instead.

Please specify the following keys for each element of users:

Name	Type	Description	Default
username	String	The username to access uchiwa dashboard
password	String	The password to access uchiwa dashboard
readonly	Boolean	Should the user have read only access?	false

Files required

You need to have the following files in the role folder (for RedHat only):

 files/
  | - sensu.repo
  | - sensu-unstable.repo

No hard dependency.

Weak dependencies on:

• Redis
• RabbitMQ
• Sensu

Tests

Vagrant

Vagrant creates a Debian-like VM (hashicorp/precise64) and a RedHat-like VM (chef/centos-6.5). The vagrant up command will trigger a standalone.yml ansible-playbook run that will test this role on the two VMs.

You can also spin up a specific vm:

vagrant up debian spins up hashicorp/precise64 vagrant up redhat spins up chef/centos-6.5

Acceptance Tests

The acceptance tests will be in the vagrant/ folder and will be integrated with travis-ci. Watch this space for more info.
