Will Foster 21f1f28ab3 Add ELK stack and ELK client Ansible playbooks.
Fixes for this patchset:
- split out elk-openstack-client.yml to match what's done elsewhere

Fixes for patchset #11:
- split out filebeat into separate role for openstack clients
- update README.md to use elk-openstack-client.yml for this purpose
- cleanup filebeat.yml.j2 to use correct syntax (no need for " anymore)

Fixes for patchset #10:
- add SELinux boolean "httpd_can_network_connect"
- add libsemanage-python package dependency for booleans

Fixes for patchset #9:
- fix for RHEL7 clients, we need to specify remote EPEL rpm
- RHEL7 clients need rpm_key module to import EPEL GPG key
- switch to using uri module instead of curl for checking elasticsearch indices
- add python-httplib2 dependency (needed for uri module)
- use curl -XPOST instead of PUT for filebeat index template in elasticsearch

Fixes from patchset #7
- remove unneeded rpm usage, switch to yum module
- add logic to heapsize tuning so systems > 64G of memory will
  never exceed the 32G recommended heapsize
- logic fix for prepopulating local logs into logstash
- remove elasticsearch.yml, rpm provides this and we're not
  customizing it yet

Fixes from patchset #6:
- use yum repo Ansible module where we can
- remove unecessary EPEL installation (only nginx needs it)
- disable EPEL repo after installation to avoid OpenStack breakage

This adds:

(ELK Server)
- Automated ELK stack deployment
- SSL client generation
- Heap size tuning (1/2 of available memory)
- Firewall port additions (depending on active or not)
  - Supports either firewalld or iptables-services
- Additional upstream Filebeat Kibana dashboards

(ELK Client)
- Sets up filebeat with appropriate SSL certificates
  - utilizes both hostnames and SubjectAltName support (for environments without
    DNS services).

(Usage)

ansible-playbook -i hosts install/elk.yml
ansible-playbook -i hosts install/elk-client.yml --extra-vars 'elk_server=X.X.X.X'

Ansible for Browbeat

Currently we support Ansible 1.9.4 within browbeat-venv and ansible 2.0 for installation.

Playbooks for:

  • Installing Browbeat, collectd, connmon, ELK stack and clients, graphite, grafana, and grafana dashboards
  • Check overcloud for performance issues
  • Tune overcloud for performance (Experimental)
  • Adjust number of workers for cinder/keystone/neutron/nova
  • Deploy keystone in eventlet/httpd
  • Adjust keystone token type to UUID/Fernet
  • Adjust neutron l3 agents
  • Adjust nova greenlet_pool_size / max_overflow

Getting Started

Install your public key into stack's authorized_keys

# ssh-copy-id stack@<undercloud-ip>

Then run gen_hosts.sh script to generate your overcloud's hosts file for ansible and generate a "jumpbox" ssh config:

# ./gen_hostfile.sh <undercloud-ip> ~/.ssh/config

*Review the hosts file the script generates.

Ansible Installers

Install Browbeat

Image upload requires Ansible 2.0

# vi install/group_vars/all  # Edit ansible vars file (Installation parameters)
# ansible-playbook -i hosts install/browbeat.yml
Install Collectd Agent (Requires a Graphite Server)

Prior to installing the agent, please review install/group_vars/all file to ensure the correct parameters are passed.

# ansible-playbook -i hosts install/collectd-openstack.yml

To install collectd on everything other than Openstack machines, view the README for collectd-generic.

Install Connmon

Requires Ansible 2.0

# ansible-playbook -i hosts install/connmon.yml
Install ELK Stack
ansible-playbook -i hosts install/elk.yml
Install ELK Clients
ansible-playbook -i hosts install/elk-openstack-client.yml --extra-vars 'elk_server=X.X.X.X'
  • elk_server variable will be generated after the ELK stack playbook runs
Install graphite service
# ansible-playbook -i hosts install/graphite.yml
Install grafana service

Prior to installing grafana, please review install/group_vars/all file and your ansible inventory file

# ansible-playbook -i hosts install/grafana.yml
Install Grafana Dashboards (Requires a Grafana Server)

Review install/group_vars/all before deploying the grafana dashboards

# ansible-playbook -i hosts install/dashboards-openstack.yml

Performance Check

Run the check playbook to identify common performance issues:

# ansible-playbook -i hosts check/site.yml

Performance Tune

Run the tune playbook to tune your OSPd deployed cloud for performance:

# ansible-playbook -i hosts tune/tune.yml

Adjust your overcloud

To modify the number of workers each service is running:

# ansible-playbook -i hosts browbeat/adjustment-workers.yml -e "workers=8"

Openstack services will be running 8 workers per service.

To modify number of workers each service is running and ensure Keystone is deployed in eventlet:

# ansible-playbook -i hosts browbeat/adjustment-workers.yml -e "workers=8 keystone_deployment=eventlet"

To run Keystone in httpd, change keystone_deployment to httpd:

# ansible-playbook -i hosts browbeat/adjustment-workers.yml -e "workers=8 keystone_deployment=httpd"

To switch to fernet tokens:

# ansible-playbook -i hosts browbeat/adjustment-keystone-token.yml -e "token_provider=fernet"

To switch to UUID tokens:

# ansible-playbook -i hosts browbeat/adjustment-keystone-token.yml -e "token_provider=uuid"
