Eucalyptus Data Warehouse

What is it?

The Eucalyptus Data Warehouse (or eucadw) is a reference implementation toolset for creating a data warehouse for your Eucalyptus reporting information. Reporting data that has been exported from a Cloud Controller can be imported into a database where reports can be generated.

Operating system requirements

These instructions assume that your data warehouse will be running CentOS or RHEL 6. Also, please note that you should not install the DW tools on a running Eucalyptus system. The installation instructions do require that Eucalyptus is built and installed only for jar files required by the DW tools. The Eucalyptus install can be removed after the DW tools have been built.

Build and install from source

In order to build the Data Warehouse from source, you will need the following:

  1. An installed copy of Eucalyptus from the testing branch (the DW needs jar files located in /usr/share/eucalyptus)
  2. Java 1.6.0 or greater
  3. Apache Ant
  4. Apache Ivy
  5. Python 2.6.x

Next, check out the DW repository:

> git clone git://github.com/eucalyptus/bodega.git
> cd bodega

Build and install java components:

> ant -Ddistro.name=centos
> mkdir -p /usr/share/java/eucadw
> cp -a lib/*.jar /usr/share/java/eucadw
> cp -a dist/*.jar /usr/share/java/eucadw

Build and install python components:

> cd eucadw
> python setup.py build
> python setup.py install

Configuring the database

Add a repository file /etc/yum.repos.d/eucaruntime.repo with the following content:

[eucaruntime]
name = Eucalyptus Runtime
baseurl = http://downloads.eucalyptus.com/software/eucalyptus/runtime-deps/3.1/centos/6/x86_64/
enabled = 1
gpgcheck = 0

Install and configure the Postgresql 9.1 packages:

> yum install postgresql91-server
> service postgresql-9.1 initdb
> service postgresql-9.1 start
> su - postgres
> psql

Now, at the psql prompt run:

> create database eucalyptus_reporting;
> create user eucalyptus with password 'mypassword';
> grant all on database eucalyptus_reporting to eucalyptus;
> exit

Edit /var/lib/pgsql/9.1/data/pg_hba.conf so that is contains the following settings:

local   all             all                                     password
host    all             all             127.0.0.1/32            password
host    all             all             ::1/128                 password

At this point the Postgresql service should be reloaded:

> service postgresql-9.1 reload

Using the DW cli tools

Now your system is configured to be used as a Data Warehouse. Check the status of the database by running:

> eucadw-status -p mypassword

You can also import data exported from your Cloud Controller using:

> eucadw-import-data -e myexportdata.txt -p mypassword
