Installation

Browbeat is currently installed via an ansible playbook. In a Tripleo environment it can be installed directly on the Undercloud or a separate machine. The installation can be run from either your local machine or directly on the machine you want Browbeat installed on.

Install Browbeat on Undercloud

This is usually the easiest installation due to many requirements are satisfied on the Undercloud. In some cases it may not be desired to install Browbeat on the Undercloud (Ex. Limited Resource requirements or Non-Tripleo installed cloud)

Requirements

Hardware

  • Undercloud Machine (Baremetal or Virtual Machine)

Networking

  • Access to Public API endpoints
  • Access to Keystone Admin Endpoint

Note

For tripleo, public API endpoints are located on the External Network by default. The Keystone Admin Endpoint is deployed on the ctlplane network by default. These networking requirements should be validated before attempting an installation.

On the Undercloud

$ ssh undercloud-root
[root@undercloud ~]# su - stack
[stack@undercloud ~]$ git clone https://github.com/openstack/browbeat.git
[stack@undercloud ~]$ cd browbeat/ansible
[stack@undercloud ansible]$ ./generate_tripleo_hostfile.sh -t localhost
[stack@undercloud ansible]$ sudo easy_install pip
[stack@undercloud ansible]$ sudo pip install ansible
[stack@undercloud ansible]$ vi install/group_vars/all.yml # Make sure to edit the dns_server to the correct ip address
[stack@undercloud ansible]$ ansible-playbook -i hosts install/browbeat.yml
[stack@undercloud ansible]$ vi install/group_vars/all.yml # Edit Browbeat network settings
[stack@undercloud ansible]$ ansible-playbook -i hosts install/browbeat_network.yml # For external access(required to build Shakerimage)
[stack@undercloud ansible]$ ansible-playbook -i hosts install/shaker_build.yml

Note

browbeat-network.yml might not work for you depending on your underlay/overlay network setup. In such cases, user needs to create appropriate networks for instances to allow them to reach the internet. Some useful documentation can be found at: https://access.redhat.com/documentation/en/red-hat-openstack-platform/11/single/networking-guide/

(Optional) Install Browbeat instance workloads

Browbeat instance workloads are orchestrated Rally plugins that ship with Browbeat. We currently support a handful of workloads

  • Pbench-Uperf - Networking throughput / RR test
  • Linpack - Microbenchmark for CPU load

To enable installation of the Browbeat workloads set install_browbeat_workloads: true in ansible/install/group_vars/all.yml.

It is also required to provide the neutron network id of a private network which has external access. To set this, edit ansible/install/group_vars/all.yml and provide the network id for the browbeat_network:

This work can either be done prior to installation of Browbeat, or after Browbeat has been installed. To skip directly to this task execute:

$ ansible-playbook -i hosts install/browbeat.yml --start-at-task "Check browbeat_network"
...

(Optional) Install Collectd

[stack@ospd ansible]$ ansible-playbook -i hosts install/collectd-openstack.yml

(Optional) Install Browbeat Grafana dashboards

[stack@ospd ansible]$ ansible-playbook -i hosts install/dashboards-openstack.yml

Run Overcloud checks

[stack@ospd ansible]$ ansible-playbook -i hosts check/site.yml

Your Overcloud check output is located in results/bug_report.log

Install Browbeat from your local machine

This installs Browbeat onto your Undercloud but the playbook is run from your local machine rather than directly on the Undercloud machine.

From your local machine

$ ssh-copy-id stack@<undercloud-ip>
$ git clone https://github.com/openstack/browbeat.git
$ cd browbeat/ansible
$ ./generate_tripleo_hostfile.sh -t <undercloud-ip>
$ vi install/group_vars/all.yml # Review and edit configuration items
$ ansible-playbook -i hosts install/browbeat.yml
$ vi install/group_vars/all.yml # Edit Browbeat network settings
$ ansible-playbook -i hosts install/browbeat_network.yml # For external access(required to build Shaker image)
$ ansible-playbook -i hosts install/shaker_build.yml

Note

browbeat-network.yml might not work for you depending on your underlay/overlay network setup. In such cases, user needs to create appropriate networks for instances to allow them to reach the internet. Some useful documentation can be found at: https://access.redhat.com/documentation/en/red-hat-openstack-platform/11/single/networking-guide/

(Optional) Install collectd

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

(Optional) Install Browbeat Grafana dashboards

$ ansible-playbook -i hosts install/grafana-dashboards.yml

Install/Setup Browbeat Machine

This setup is used when running Browbeat on a separate machine than the Undercloud. Using this method, you can create multiple users on the machine and each user can be pointed at a different cloud or the same cloud.

Requirements

Hardware

  • Baremetal or Virtual Machine

Networking

  • Access to Public API endpoints
  • Access to Keystone Admin Endpoint

RPM

  • epel-release
  • ansible
  • git

OpenStack

  • overcloudrc file placed in browbeat user home directory

Note

For tripleo, public API endpoints are located on the External Network by default. The Keystone Admin Endpoint is deployed on the ctlplane network by default. These networking requirements should be validated before attempting an installation.

Preparing the Machine (CentOS 7)

  1. Install Machine either from Image, ISO, or PXE
  2. Check for Required Network Connectivity

Note

In SSL environments, you must copy the certificate over and check that the “OS_CA_CERT” variable is set correctly to the copied certificate location

  1. Install RPM requirements
[browbeat1@browbeatvm ~]$ sudo yum install -y epel-release
[browbeat1@browbeatvm ~]$ sudo yum install -y ansible git
  1. Clone Browbeat
[browbeatuser1@browbeat-vm ~]$ git clone https://github.com/openstack/browbeat.git
Cloning into 'browbeat'...

Resolving deltas: 100% (4280/4280), done.
  1. Generate hosts, ssh-config, and retrieve heat-admin-id_rsa.
[browbeat1@browbeatvm ~]$ cd browbeat/ansible/
[browbeat1@browbeatvm ansible]$ ./generate_tripleo_hostfile.sh -t undercloud-1 --localhost
...
[browbeat1@browbeatvm ansible]$ ls ssh-config hosts heat-admin-id_rsa
heat-admin-id_rsa  hosts  ssh-config

Note use of “–localhost” to indicate the desire to install browbeat on the localhost rather than the undercloud.

  1. Edit installation variables
[browbeat1@browbeatvm ansible]$ vi install/group_vars/all.yml

In this case, adjust browbeat_user, iptables_file and dns_server. Each environment is different and thus your configuration options will vary.

Note

If you require a proxy to get outside your network, you must configure http_proxy, https_proxy, no_proxy variables in the proxy_env dictionary in install/group_vars/all.yml

  1. Run Browbeat install playbook
[browbeat1@browbeatvm ansible]$ ansible-playbook -i hosts install/browbeat.yml
  1. Setup browbeat-config.yaml and test run Rally against cloud
[browbeat1@browbeatvm ansible]$ cd ..
[browbeat1@browbeatvm browbeat]$ vi browbeat-config.yaml
[browbeat1@browbeatvm browbeat]$ . ../browbeat-venv/bin/activate
(browbeat-venv) [browbeat1@browbeatvm browbeat]$ python browbeat.py rally

Make sure to modify the venv settings for Rally to match the directory in which Rally was installed in. You will have to do so for other workload providers as well.

  1. Setup network for Shaker+PerfKitBenchmarker and build Shaker image
[browbeatuser1@browbeat-vm ~]$ vi install/group_vars/all.yml # Edit Browbeat network settings
[browbeatuser1@browbeat-vm ~]$ ansible-playbook -i hosts install/browbeat_network.yml # For external access(required to build Shaker image)
[browbeatuser1@browbeat-vm ~]$ ansible-playbook -i hosts install/shaker_build.yml

Note

browbeat-network.yml might not work for you depending on your underlay/overlay network setup. In such cases, user needs to create appropriate networks for instances to allow them to reach the internet. Some useful documentation can be found at: https://access.redhat.com/documentation/en/red-hat-openstack-platform/11/single/networking-guide/

(Optional) Install collectd

[browbeatuser1@browbeat-vm ~]$ ansible-playbook -i hosts install/collectd-openstack.yml

(Optional) Install Browbeat Grafana dashboards

[browbeatuser1@browbeat-vm ~]$ ansible-playbook -i hosts install/grafana-dashboards.yml

Considerations for additional Browbeat Installs

If it is desired to run Browbeat against multiple clouds from the same machine. It is recommended to create a second user (Ex. browbeat2) and repeat above instructions. In order to expose the second user’s Browbeat results via httpd, change the port (Variable browbeat_results_port) and thus each user’s results will be available via http on different ports.

Note

Keep in mind that running multiple sets of control plane workloads from multiple Browbeat users at the same time will introduce variation into resulting performance data if the machine on which Browbeat is installed is resource constrained.

Using Keystone Public Endpoint

If your Browbeat installation can not reach the Keystone Admin API endpoint due to the networking, you can use Keystone V3 options. In your overcloudrc or rc file you can add the following environment variables.

export OS_IDENTITY_API_VERSION=3
export OS_INTERFACE=public

Uploading Images to the overcloud

Browbeat by default uploads CentOS and CirrOS images to the cloud for use in Rally and other workloads. It is recommended to upload RAW images if using ceph and hence the convert_to_raw variable must be set to true as shown below in ansible/install/group_vars/all.yml. The default is false.

images:
  centos7:
    name: centos7
    url: http://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud.qcow2
    type: qcow2
    convert_to_raw: true

Additional Components Installation

Install Monitoring Host (Carbon/Graphite/Grafana)

A monitoring host exposes System and Application performance metrics to the Browbeat user via Grafana. It helps expose what may be causing your bottleneck when you encounter a performance issue.

  1. Add a hosts file into ansible directory
[root@dhcp23-93 ~]# cd browbeat/ansible/
[root@dhcp23-93 ansible]# vi hosts

Content of hosts file should be following

[graphite]
localhost

[grafana]
localhost
  1. Setup SSH config, SSH key and exchange for Ansible
[root@dhcp23-93 ansible]# touch ssh-config
[root@dhcp23-93 ansible]# ssh-keygen

...
[root@dhcp23-93 ansible]# ssh-copy-id root@localhost
...
  1. Edit install variables
[root@dhcp23-93 ansible]# vi install/group_vars/all.yml

Depending on the environment you may need to edit more than just the following variables - graphite_host and grafana_host

Note

If you require a proxy to get outside your network, you must configure http_proxy, https_proxy, no_proxy variables in the proxy_env dictionary in install/group_vars/all.yml

  1. Install Carbon and Graphite via Ansible playbook
[root@dhcp23-93 ansible]# ansible-playbook -i hosts install/graphite.yml
...
  1. Install Grafana via Ansible playbook
[root@dhcp23-93 ansible]# ansible-playbook -i hosts install/grafana.yml

[root@dhcp23-93 ansible]# ansible-playbook -i hosts install/collectd-generic.yml --tags graphite
...

Now navigate to http://monitoring-host-address:3000 to verify Grafana is installed, the Graphite data source exists and custom dashboards are uploaded.

You can now point other clouds at this host in order to view System and Application performance metrics. Depending on the number of clouds and machines pointed at your monitoring server, you may need to add more disk IO capacity, disk storage or carbon-cache+carbon-relay processes depending entirely on the number of metrics and your environments capacity. There is a Graphite dashboard included and it is recommended to install collectd on your monitoring host such that you can see if you hit resource issues with your monitoring host.

Install ELK Host (ElasticSearch/LogStash/Kibana)

An ELK server allows you to publish resulting benchmark data into ElasticSearch which allows you to build querys and dashboards to examine your benchmarking result data over various metadata points.
