Overview

Koala is a billing system for openstack driven by ceilometer event.

Koala only interacts with ceilometer by Rest API. Once Ceilometer receive a notification from message bus, it will send the event converted from notification to Koala. With the event, koala caculates the consumption and generates the billing records.

Koala is designed as distribute system with following characteristics.

  • High-resolution timing as second level precision
  • Supports to multi-regions
  • High efficient driven by events
  • Decoupling from openstack
  • Distribute with stateless service

#Architecture ##koala-api The koala-api provide rest APIs for ceilometer and users, the event API is used to recieve events from ceilometer and the others are designed to privde for query billing records.

API

    "content": {"size": 100}
}

Install

You can install koala from python source or RPM. To install from python source, just run

    [root@controller koala]# python setup.py install

To install from RPM, you need to build the RPM first with following scripts.

    PBR_VERSION=$(grep Version: /root/koala/contrib/koala.spec | awk '{print $2}') 
    export PBR_VERSION=${PBR_VERSION} 
    cd /root/koala 
    python setup.py sdist 
    rm -rf /root/rpmbuild/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS}/* 
    cp dist/koala-${PBR_VERSION}.tar.gz /root/rpmbuild/SOURCES 
    cp -R /root/koala/contrib/. /root/rpmbuild/SOURCES 
    cp /root/koala/contrib/koala.spec /root/rpmbuild/SPECS/ 
    cp /root/koala/etc/koala/koala.conf.sample  /root/rpmbuild/SOURCES
    rpmbuild -bs /root/rpmbuild/SPECS/koala.spec 
    yum-builddep /root/rpmbuild/SRPMS/koala-*.src.rpm 
    rpmbuild -bb /root/rpmbuild/SPECS/koala.spec

Then you can install the RPM in /root/rpmbuild/RPMS/noarch/
