+Introduction
+============
+
+This document describes the steps required to install, configure and verify the
+operation of collectd with ceilometer plugin with Kolla.
+
+Pre-requisites
+==============
+
+- Access to the internet
+- Keystaone and Ceilometer enabled
+
+Installation of Kolla
+=====================
+
+Please refer to this doc for instructions about how to install kolla.
+
+    http://docs.openstack.org/developer/kolla/quickstart.html
+
+For the simplest installation follow the instructions for evaluation and
+development purposes.
+
+Install Collectd with Kolla
+===========================
+
+To install collectd with kolla, edit the ``globals.yml`` file and change the
+following settings:
+
+* Enable collectd so that its container is created. Additionally, enable
+  ceilometer and mongodb to ensure the ceilometer service is installed.
+
+::
+
+  enable_collectd: "yes"
+  enable_ceilometer: "yes"
+  enable_mongodb: "yes"
+
+* Edit the network settings to suit your environment by changing the
+  following:
+
+::
+
+   kolla_internal_vip_address:
+   network_interface:
+   neutron_external_interface:
+
+* To customize the images that are built with kolla change:
+
+::
+
+  kolla_base_distro:
+  kolla_install_type:
+
+In the kolla-build.conf file uncomment/paste the following lines into
+the plugins section.
+
+::
+
+    [collectd-plugin-collectd-ceilometer-plugin]
+    type = git
+    location = https://github.com/openstack/collectd-ceilometer-plugin.git
+    reference = master
+
+To build the collectd container with the collectd-ceilometer-plugin
+repository, copy the ``template-override.json`` file to a local directory.
+Run the following command to build the container.
+
+::
+
+    kolla-build --template-override <path_to_template_override_file>
+
+Verification of Collectd
+========================
+
+To verify the successful build of the collectd image run the following command.
+
+::
+
+    docker images | grep  -i collectd
+
+Follow the steps in the Kolla documentation to install OpenStack, which are
+provided above. Run the following command to check if the collectd container
+is up and running.
+
+::
+
+    docker ps |grep -i collectd
+
+The status of the collectd container should be "Up".
+
+Configure collectd-ceilometer-plugin
+====================================
+
+Edit the ``/kolla/etc/collectd-ceilometer-plugin.conf`` file and replace the
+varaiables with appropriate values. The passwords and endpoints will be
+provided by the operator. If these entries are not provided, run the
+post-deploy script as mentioned in the Kolla guide to generate the passwords
+and endpoints.
+
+The other entries you need to edit in this file are outlined below:
+
+* Include the "ModulePath" to the collectd-ceilometer-plugin directory.
+
+::
+
+  ModulePath "/path/to/module"
+
+* Specify your endpoint address, OS_AUTH_URL "<OS_AUTH_URL>". To determine this
+  address, use your openstack client, run the following command and select the
+  keystone internalURL.
+
+  | openstack catalog list
+
+* The CEILOMETER_URL_TYPE should be set for you, but if not set it to
+  "internalURL".
+
+Copy this config file to ``/etc/kolla/collectd/collectd.conf.d`` folder.
+
+| sudo cp collectd-ceilometer-plugin.conf /etc/kolla/collectd/collectd.conf.d
+
+Restart the collectd container for the changes to take affect.
+
+| docker restart collectd
+
+Verify the container is up and running.
+
+Verification of collectd-ceilometer-plugin
+==========================================
+
+To verify that the plugin is working, use the ceilometer client.
+
+* Source the credentials provided by the kolla post-deploy script.
+
+| source admin-openrc.sh
+
+* To verify that the stats are going through to ceilometer, view the meter
+  list created by ceilometer.
+
+| ceilometer meter-list
+
+  Check this list for the default meters that are enabled by collectd. One of
+  these is "cpu.cpu". Check the ceilometer sample list for this meter, to
+  confirm it is enabled.
+
+| ceilometer sample-list --meter cpu.cpu
