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
|
|
|
|
.. code-block:: bash
|
|
|
|
cd /opt
|
|
git clone https://git.openstack.org/openstack/openstack-ansible-ops
|
|
|
|
Copy the env.d files into place
|
|
|
|
.. code-block:: bash
|
|
|
|
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
|
|
|
|
.. code-block:: bash
|
|
|
|
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
|
|
|
|
.. code-block:: bash
|
|
|
|
openstack-ansible playbook-metrics-lb.yml
|
|
|
|
Create the containers
|
|
|
|
.. code-block:: bash
|
|
|
|
openstack-ansible /opt/openstack-ansible/playbooks/lxc-containers-create.yml -e container_group=cluster-metrics
|
|
|
|
Install InfluxDB
|
|
|
|
.. code-block:: bash
|
|
|
|
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.
|
|
|
|
.. code-block:: bash
|
|
|
|
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/'``
|
|
|
|
.. code-block:: bash
|
|
|
|
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
|
|
|
|
.. code-block:: bash
|
|
|
|
openstack-ansible playbook-kapacitor.yml
|
