Code Issues Proposed changes

Will Foster b29d74f4de Replace dummy 1.1.1.1 values for graphite_host, grafana_host 
This adds a sanity check that will fail if the user has not filled out
the grafana_host and graphite_host values in group_vars/all.yml

It will cause the grafana playbook execution to fail with a debug warning
which is cleaner than having it execute all the way through only to fail later.

We would ship these entries defined but empty as a result.

Patchset #2: correct typo in commit title
Patchset #3: move to top of playbook so if it fails it will be right away.
Patchset #4: README.MD update: specify that these values need to be filled in

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.

Install graphite service
# ansible-playbook -i hosts install/graphite.yml
Install graphite service as a docker container

# ansible-playbook -i hosts install/graphite-docker.yml
Install grafana service

Prior to installing grafana, please review install/group_vars/all.yml file and your ansible inventory file You will need to define values for the grafana_host and graphite_host IP addresses here.

# ansible-playbook -i hosts install/grafana.yml
Install grafana service as a docker container

Prior to installing graphite as a docker container, please review install/group_vars/all.yml file and ensure the docker related settings will work with your target host.

# 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

# 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"
