Kevin Carter 5b93b9a2c2 Added nova quota plugin

This change adds a second plugin to the telegraf setup. A change is
being made to the telegraf config file to allow for more than one
external plugin to be executed and to allow for full plugin execution
between telegraf reporting intervals.

Each plugin will potentially account for up to 8 seconds of runtime with
the telegraf agent now using a dynamic reporting interval based on the
number of plugins a given agent is needing to execute.

About this repository

This set of playbooks will deploy InfluxDB, Telegraf, Grafana 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 to enable the grafana port 8089

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

Install Influx Telegraf

If you wish to install telegraf and point it at a specific target, or list of targets, set the influx_telegraf_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 grafana

If you're proxy'ing grafana you will need to provide the full root_path when you run the playbook add the following -e grafana_root_url='https://cloud.something:8443/grafana/'

openstack-ansible playbook-grafana.yml -e galera_root_user=root -e galera_address='127.0.0.1'

Once that last playbook is completed you will have a functioning InfluxDB, Telegraf, and Grafana metric collection system active and collecting metrics. Grafana will need some setup, however functional dashboards have been provided in the grafana-dashboards directory.

Install Kapacitor

openstack-ansible playbook-kapacitor.yml
