About this repository

This set of playbooks will deploy elk cluster (Elasticsearch, Logstash, Kibana) with topbeat to gather metrics from hosts metrics to the ELK cluster.

Process

Clone the elk-osa repo

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

Copy the env.d file into place

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

Copy the conf.d file into place

cp conf.d/elk.yml /etc/openstack_deploy/conf.d/

In elk.yml, list your logging hosts under elastic-logstash_hosts to create the elasticsearch cluster in multiple containers and one logging host under kibana_hosts to create the kibana container

vi /etc/openstack_deploy/conf.d/elk.yml

Create the containers

cd /opt/openstack-ansible-playbooks
openstack-ansible lxc-containers-create.yml -e 'container_group=elastic-logstash:kibana'

install master/data elasticsearch nodes on the elastic-logstash containers

cd /opt/openstack-ansible-ops
openstack-ansible installElastic.yml -e elk_hosts=elastic-logstash -e node_master=true -e node_data=true

Install an Elasticsearch client on the kibana container to serve as a loadbalancer for the Kibana backend server

openstack-ansible installElastic.yml -e elk_hosts=kibana -e node_master=false -e node_data=false

Install Logstash on all the elastic containers

openstack-ansible installLogstash.yml

Install Kibana, nginx reverse proxy and metricbeat on the kibana container

openstack-ansible installKibana.yml

Conigure haproxy endpoints:

Edit the /etc/openstack_deploy/user_variables.yml file and add fiel following lines:

haproxy_extra_services:
 - service:
      haproxy_service_name: kibana
      haproxy_ssl: False
      haproxy_backend_nodes: "{{ groups['kibana'] | default([]) }}"
      haproxy_port: 81
      haproxy_balance_type: tcp

and then run the haproxy-install playbook .. code-block:: bash cd /opt/openstack-ansible/playbooks/ openstack-ansible haproxy-install.yml --tags=haproxy-service-config

install Metricbeat everywhere to start shipping metrics to our logstash instances

openstack-ansible installMetricbeat.yml

Trouble shooting:

If everything goes bad, you can clean up with the following command:
