Vitrage Notifier plugins - AODH
===============================
Overview
========
The Evaluator performs root cause analysis on the Vitrage Graph and may determine that an alarm should be created, deleted or otherwise updated.
Other components are notified of such changes by the Vitrage Notifier service. Among others, Vitrage Notifier is responsible for handling Aodh Alarms.
This document describes the implementation of Vitrage Notifier infrastructure and specifically notifying Aodh on Vitrage alarms.
Design
======
::
+----------+ +-----------+ +------+ +--------+

| Aodh |<----------------------+
+------------------+
...
DeducedAlarmNotifier class will be subscribed to entity graph notifications. Whenever a vitrage deduced alarm is added to the graph it will post a message to the message bus.
The processor will hold an instance of the DeducedAlarmNotifier class and will subscribe this instance to entity graph notifications.
The VitrageNotifier is a new service that listens to the bus for internal vitrage notifications, then can call all the relevant notifier plugins.
1. Deduced Alarm created by the Evaluator
2. Graph vertex added/updated
3. DeducedAlarmNotifier writes to message bus
4. VitrageNotifierService receives the event and calls all plugins
5. Aodh plugin - using the ceilometer client, creates an event in aodh (with some metadata params in the query)
Deduced Alarms bus notifications
--------------------------------
Vitrage Evaluator will create a deduced alarm, sending it to the data source queue
Vitrage Evaluator will use the **vitrage.graph** message bus topic, and will post messages as follows:
- message of type ``vitrage.deduced_alarm.activate`` :
* ``name`` - is the alarm name in vitrage
* ``severity`` - is the alarm severity
* ``affected_resource_id`` - is the openstack id of the resource on which the alarm was raised
- ``vitrage.deduced_alarm.deactivate``
* ``id`` - is the alarm id
Notifier
========
- Is a new running service
- Receives notifications from the message bus
- Holds instances of all the plugins
- Upon a received notification, calls 'notify(msg)' for all the plugins
- Each plugin is responsible of how and whether to process the notification
Aodh Plugin
===========
Vitrage alarms should be reflected as possible in Aodh. The aodh plugin has ceilometer client by which it can send rest calls to aodh
Handle ``vitrage.deduced_alarm.activate``
-----------------------------------------
Create an event alarm with the specified severity, where the alarm name is ``vitrage_alarm_name+resource_id`` so to be unique
- Message does not contain aodh alarm id:
* plugin will **create** a new aodh alarm
* alarm type - event
* alarm status - alarm
* query contain resource_id, vitrage_id fields
- Message contains aodh alarm id
* plugin will **update** the aodh alarm status to alarm
Handle ``vitrage.deduced_alarm.deactivate``
-------------------------------------------
Delete an event alarm with the specified id
* message will contain the aodh alarm id - plugin will **update** the alarm status to ok

Vitrage Manual Installation
===========================
Install Vitrage
===============
Install vitrage and python-vitrageclient
----------------------------------------
To install the Ocata release:
.. code:: bash
sudo pip install vitrage==1.5.1
sudo pip install python-vitrageclient==1.1.1
Or, to install the latest version:
.. code:: bash
sudo pip install vitrage
sudo pip install python-vitrageclient
Configure Vitrage
=================
Create the Vitrage folders
--------------------------
Create /etc/vitrage folder and sub folders, **with permission 755**
.. code:: bash
mkdir /etc/vitrage
chmod 755 /etc/vitrage
mkdir /etc/vitrage/static_datasources
chmod 755 /etc/vitrage/static_datasources
mkdir /etc/vitrage/templates
chmod 755 /etc/vitrage/templates
sudo mkdir /var/log/vitrage
sudo chmod 755 /var/log/vitrage
Copy `policy.json`_ to /etc/vitrage/
Copy `api-paste.ini`_ to /etc/vitrage/
Copy the `datasources_values`_ folder with its content
**Note:** You don't need to copy all files in this folder, only the ones that
belong to datasources you plan to use. The only file that **must** be copied
is vitrage.yaml
.. _policy.json: ../../etc/vitrage/policy.json
.. _api-paste.ini: ../../etc/vitrage/api-paste.ini
.. _datasources_values: ../../etc/vitrage/datasources_values
Create the vitrage.conf file
----------------------------
Create /etc/vitrage/vitrage.conf file with the following information:
.. code:: bash
[DEFAULT]
# debug = False
transport_url = <transport-url>
# notifiers = nova
[service_credentials]
auth_url = http://<ip>:5000
region_name = RegionOne
project_name = admin
password = <password>
project_domain_id = default
user_domain_id = default
username = admin
auth_type = password
[keystone_authtoken]
auth_uri = http://<ip>:5000
project_domain_name = Default
project_name = service
user_domain_name = Default
password = <password>
username = vitrage
auth_url = http://<ip>:35357
auth_type = password
Set the list of datasource you would like to use for Vitrage.
**Note:** In order for a datasource to be supported, the underlying component
(like Neutron, Heat, Zabbix, etc.) should be installed separately.
.. code:: bash
[datasources]
types = nova.host,nova.instance,nova.zone,static,aodh,cinder.volume,neutron.network,neutron.port,heat.stack,doctor
Configure notifications from other datasources
==============================================
Notifications from Aodh
-----------------------
In order to configure notifications from Aodh to Vitrage, set the following in
`/etc/aodh/aodh.conf`:
.. code:: bash
[oslo_messaging_notifications]
driver = messagingv2
topics = notifications,vitrage_notifications
Notifications from other OpenStack components
---------------------------------------------
In order to configure notifications from OpenStack components (Nova, Cinder,
Neutron, Heat and Aodh) to Vitrage, set the following in their conf files:
.. code:: bash
[DEFAULT]
notification_topics = notifications,vitrage_notifications
notification_driver=messagingv2
Initialize Vitrage
==================
Create the Vitrage account
--------------------------
.. code:: bash
openstack user create vitrage --password password --domain=Default
openstack role add admin --user vitrage --project service
openstack role add admin --user vitrage --project admin
Create the Vitrage endpoint
---------------------------
.. code:: bash
openstack service create rca --name vitrage --description="Root Cause Analysis Service"
openstack endpoint create --region <region> --publicurl http://<ip>:8999 --internalurl http://<ip>:8999 --adminurl http://<ip>:8999 vitrage
Start the Vitrage Services
==========================
Run the following commands:
.. code:: bash
vitrage-graph
vitrage-api
vitrage-notifier
Install the Vitrage Dashboard
=============================
