The opstools-ansible project is a collection of Ansible roles and playbooks that will configure an environment that provides centralized logging and analysis, availability monitoring, and performance monitoring.
Before using the opstools-ansible playbook, you will need to deploy one or more servers on which you will install the opstools services. These servers will need to be running either CentOS 7 or RHEL 7 (or a compatible distribution).
These playbooks will install packages from a number of third-party repositories. The opstools-ansible developers are unable to address problems with the third party packaging (other than via working around problems in our playbooks).
Create an Ansible inventory file inventory/hosts that defines your
hosts and maps them to host groups declared in inventory/structure.
For example:
server1 ansible_host=192.0.2.7 ansible_user=centos ansible_become=true server2 ansible_host=192.0.2.15 ansible_user=centos ansible_become=true [am_hosts] server1 [pm_hosts] server2 [logging_hosts] server2
There are three high-level groups that can be used to control service placement:
am_hosts: The playbooks will install availability monitoring software (Sensu, Uchiwa, and support services) on these hosts.
pm_hosts: The playbooks will install performance monitoring software (Gnocchi or graphite)
logging_hosts: The playbooks will install the centralized logging stack (Elasticsearch, Kibana, Fluentd) on these hosts.
While there are more groups defined in the inventory/structure file,
use of those for more granular service placement is neither tested nor
supported at this time.
You can also run post-install playbook after overcloud deployment to finish server side configuration dependent on the information about the overcloud. For that you will need to add undercloud host to the inventory. So for example, after deploying overcloud via tripleo-quickstart tool, you should add something like following to the inventory file before running the playbook:
undercloud_host ansible_user=stack ansible_host=undercloud ansible_ssh_extra_args='-F "/root/.quickstart/ssh.config.ansible"'
Put any necessary configuration into an Ansible variables file (which is just a YAML document). For example, if you wanted to enable logging via SSL, you would need a configuration file that looked like this:
fluentd_use_ssl: true fluentd_shared_key: secret fluentd_ca_cert: | -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- fluentd_private_key: | -----BEGIN RSA PRIVATE KEY----- ... -----END RSA PRIVATE KEY-----
You can also influence the data storage being used for performance metrics. It can be either gnocchi or graphite, which should work in most cases. For more details, please visit group_vars/all.yml.
You don't need a configuration file if you wish to use default options.
Once you have your inventory and configuration in place, you can run the playbook like this:
ansible-playbook playbook.yml -e @config.yml
