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
|
|
|
|
.. code-block:: bash
|
|
|
|
cd /opt
|
|
git clone https://git.opendev.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.
|
|
|
|
.. 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
|
|
|
|
Clone the Telegraf repo
|
|
|
|
.. code-block:: bash
|
|
|
|
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.
|
|
|
|
.. code-block:: bash
|
|
|
|
openstack-ansible playbook-influx-telegraf.yml --forks 100
|
|
|
|
Install Kapacitor
|
|
|
|
.. code-block:: bash
|
|
|
|
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``:
|
|
|
|
.. code-block:: yaml
|
|
|
|
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 :
|
|
|
|
.. code-block:: bash
|
|
|
|
cd /opt/openstack-ansible/playbooks
|
|
openstack-ansible os-swift-setup.yml --tags swift-config --forks 2
