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]$ ansible-playbook -i hosts install/shaker_build.yml
|
|
|
|
.. note:: Your default network 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 Rsyslogd logging with aggregation
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
First configure the values rsyslog values and elasticsearch parameters in
|
|
`ansible/install/group_vars/all.yml`. If you have a large number of hosts
|
|
deploying an aggregator using `ansible/install/rsyslog-aggregator.yml`
|
|
is strongly suggested. If you have a small scale, change the value
|
|
rsyslog_forwarding in `all.yml` to `false`. Once things are configured
|
|
to your liking deploy logging on the cloud using the `rsyslog-logging.yml`
|
|
playbook.
|
|
|
|
Firewall configuration for the aggregator is left up to the user. The logging
|
|
install playbook will check that the aggregator is up and the port is open if
|
|
you deploy with aggregation.
|
|
|
|
::
|
|
|
|
[stack@ospd ansible]$ vim install/group_vars/all.yml
|
|
[stack@ospd ansible]$ ansible-playbook -i hosts install/rsyslog-aggregator.yml
|
|
[stack@ospd ansible]$ ansible-playbook -i hosts install/rsyslog-logging.yml
|
|
|
|
(Optional) Install Browbeat Grafana dashboards
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
::
|
|
|
|
[stack@ospd ansible]$ ansible-playbook -i hosts install/dashboards-openstack.yml
|
|
|
|
Not mantained (Pre-Pike): 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
|
|
$ ansible-playbook -i hosts install/shaker_build.yml
|
|
|
|
|
|
.. note:: Your default network 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:

$ 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.

4. Enable passwordless SSH into localhost and Undercloud then copy overcloudrc over to Browbeat VM
|
|
|
|
::
|
|
|
|
[browbeat1@browbeatvm ansible]$ ssh-copy-id browbeat1@localhost
|
|
/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
|
|
/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
|
|
browbeat1@localhost's password:
|
|
|
|
Number of key(s) added: 1
|
|
|
|
Now try logging into the machine, with: "ssh 'browbeat1@localhost'"
|
|
and check to make sure that only the key(s) you wanted were added.
|
|
|
|
[browbeat1@browbeatvm ~]$ ssh-copy-id stack@undercloud-1
|
|
The authenticity of host 'undercloud-1 (undercloud-1)' can't be established.
|
|
ECDSA key fingerprint is fa:3a:02:e8:8e:92:4d:a7:9c:90:68:6a:c2:eb:fe:e1.
|
|
Are you sure you want to continue connecting (yes/no)? yes
|
|
/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
|
|
/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
|
|
stack@undercloud-1's password:
|
|
|
|
Number of key(s) added: 1
|
|
|
|
Now try logging into the machine, with: "ssh 'stack@undercloud-1'"
|
|
and check to make sure that only the key(s) you wanted were added.
|
|
|
|
[browbeat1@browbeatvm ~]$ scp stack@undercloud-1:/home/stack/overcloudrc .
|
|
overcloudrc 100% 553 0.5KB/s 00:00
|
|
|
|
.. 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
|
|
|
|
5. Install RPM requirements
|
|
|
|
::
|
|
|
|
[browbeat1@browbeatvm ~]$ sudo yum install -y epel-release
|
|
[browbeat1@browbeatvm ~]$ sudo yum install -y ansible git
|
|
|
|
6. Clone Browbeat
|
|
|
|
::
|
|
|
|
[browbeatuser1@browbeat-vm ~]$ git clone https://github.com/openstack/browbeat.git
|
|
Cloning into 'browbeat'...
|
|
remote: Counting objects: 7425, done.
|
|
remote: Compressing objects: 100% (15/15), done.
|
|
remote: Total 7425 (delta 14), reused 12 (delta 12), pack-reused 7398
|
|
Receiving objects: 100% (7425/7425), 5.23 MiB | 0 bytes/s, done.
|
|
Resolving deltas: 100% (4280/4280), done.
|
|
|
|
7. 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.
|
|
|
|
8. 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
|
|
|
|
9. Run Browbeat install playbook
|
|
|
|
::
|
|
|
|
[browbeat1@browbeatvm ansible]$ ansible-playbook -i hosts install/browbeat.yml
|
|
|
|
10. 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
|
|
|
|
11. Build Shaker image
|
|
|
|
::
|
|
|
|
[browbeatuser1@browbeat-vm ~]$ ansible-playbook -i hosts install/shaker_build.yml
|
|
|
|
.. note:: Your default network 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.

4. 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
|
|
|
|
5. Setup SSH config, SSH key and exchange for Ansible
|
|
|
|
::
|
|
|
|
[root@dhcp23-93 ansible]# touch ssh-config
|
|
[root@dhcp23-93 ansible]# ssh-keygen
|
|
Generating public/private rsa key pair.
|
|
...
|
|
[root@dhcp23-93 ansible]# ssh-copy-id root@localhost
|
|
...
|
|
|
|
6. 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
|
|
|
|
7. Install Carbon and Graphite via Ansible playbook
|
|
|
|
::
|
|
|
|
[root@dhcp23-93 ansible]# ansible-playbook -i hosts install/graphite.yml
|
|
...
|
|
|
|
8. Install Grafana via Ansible playbook
|
|
|
|
::
|
|
|
|
[root@dhcp23-93 ansible]# ansible-playbook -i hosts install/grafana.yml
|
|
...
|
|
|
|
9. Install Grafana dashboards via Ansible playbook
|
|
|
|
::
|
|
|
|
[root@dhcp23-93 ansible]# ansible-playbook -i hosts install/grafana-dashboards.yml -e 'cloud_dashboards=false'
|
|
...
|
|
|
|
10. (Optional) Monitor the Monitor Host
|
|
|
|
::
|
|
|
|
[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.
