Kevin Carter 969a30c6c7 Add grafana 
This change introduces grafana into the stack which gives us a great
way to visualize the data. The grafana role from cloudalchemy is being
used for the bulk of the deployment.
Because the grafana deployment playbook is now standalone the mentions
of grafana in the other ops directories have been removed.

About this repository

This set of playbooks will deploy InfluxDB, Telegraf, and Kapacitor for the purpose of collecting metrics on an OpenStack cluster.

Process

Clone the OPS repo

 cd /opt
 git clone https://git.openstack.org/openstack/openstack-ansible-ops

Copy the env.d files into place

 cd openstack-ansible-ops/cluster_metrics
 cp etc/env.d/cluster_metrics.yml /etc/openstack_deploy/env.d/

Add the export to update the inventory file location

 export ANSIBLE_INVENTORY=/opt/openstack-ansible/playbooks/inventory/dynamic_inventory.py

If you are running the HA Proxy you should run the following playbook as well.

 openstack-ansible playbook-metrics-lb.yml

Create the containers

 openstack-ansible /opt/openstack-ansible/playbooks/lxc-containers-create.yml -e container_group=cluster-metrics

Install InfluxDB

 openstack-ansible playbook-influx-db.yml

Clone the Telegraf repo

 git clone https://github.com/mgrzybek/openstack-ansible-telegraf /etc/ansible/roles/openstack-ansible-telegraf

Install Influx Telegraf

If you wish to install telegraf and point it at a specific target, or list of targets, set the telegraf_output_influxdb_targets variable in the user_variables.yml file as a list containing all targets that telegraf should ship metrics to.

 openstack-ansible playbook-influx-telegraf.yml --forks 100

Install Kapacitor

 openstack-ansible playbook-kapacitor.yml

OpenStack Swift PRoxy Server Dashboard

Once the telegraf daemon is installed onto each host, the Swift proxy-server can be instructed to forward statsd metrics to telegraf. The following configuration enabled the metric generation and need to be added to the user_variables.yml:

 swift_proxy_server_conf_overrides:
 DEFAULT:
 log_statsd_default_sample_rate:10
 log_statsd_metric_prefix:"{{ inventory_hostname }}.swift"
 log_statsd_host: localhost
 log_statsd_port:8125

Rewrite the swift proxy server configuration with :

 cd /opt/openstack-ansible/playbooks
 openstack-ansible os-swift-setup.yml --tags swift-config --forks 2
