<title>Install the Metering Service</title>
<procedure>
<title>Install the central Metering Service components</title>
<para>The Metering service consists of an API service, collector,
and a range of disparate agents. This procedure details how to
install the core components before you install the agents
elsewhere, such as on the compute node.</para>
<note os="debian">
<title>Note for Debian users</title>
<para>As for the rest of OpenStack, you configure the Metering
Service through the <filename>debconf</filename> file. You do
not need to manually configure the API endpoint and the
RabbitMQ parameters of Ceilometer. However, you must configure
the metering_secret and the auth_token manually.</para>
<para>If you must reconfigure the Metering Service, run the
following command:</para>
<screen><prompt>#</prompt> <userinput>dpkg-reconfigure -plow ceilometer-common</userinput></screen>
<para>Alternatively, edit the configuration files and manually
restart the daemons.</para>
</note>
<step>
<para>Install the Metering Service on the controller
node:</para>

<para>The Metering Service uses a database to store information.
Specify the location of the database in the configuration
file. The examples in this guide use a MongoDB database on the
controller node.</para>
