About Rally
Rally is the introduction of open-source OpenStack community testing tool that can be used for performance testing various components of OpenStack.
By using Rally assembly, the user can complete the installation and deployment OpenStack cloud computing platform, functional verification, test load mass (performance tests), a series of test report output operation.
Rally installation
In icos environment, directly open rally in globals.yml in.
enable_rally: "yes"
Then install the tag can be deployed.
If the host is a performance test designed to close the like, it is recommended rally machine installed on a non-testing node.
Installing the following parameters optimization, rally profile location: /etc/rally/rally.conf
Default comment all the options, testing encounter the following problems:
- Gets the instance state Timeout
- Connection timed out
Make the following settings to avoid timeouts affect the test results, the time setting 1800s:
[DEFAULT] openstack_client_http_timeout = 1800.0 [benchmark] cinder_volume_create_timeout = 1800.0 cinder_volume_delete_timeout = 1800.0 nova_server_boot_timeout = 1800.0 nova_server_boot_timeout = 1800.0
rally use
Creating Deployment
For already installed systems deployed OpenStack, there are two ways to create deployment
1) use environment variables to create
(rally)[root@node135 ~]# more openrc export OS_TENANT_NAME=admin export OS_USERNAME=admin export OS_PASSWORD=xxxx export OS_AUTH_URL=http://100.2.28.139:35357 #生效一下 source openrc #创建 rally deployment create --fromenv --name=existing
2) using the json file creation
rally deployment create--file=existing.json --name=existing
existing template file default location / rally-openstack / samples / deployments
existing.json document reads as follows:
{
"type":"ExistingCloud",
"auth_url": "http://10.25.*.*:35357/v3",
"region_name":"RegionOne",
"endpoint_type":"public",
"admin": {
"username":"admin",
"password": "****",
"tenant_name": "admin"
},
"users": [
{
"username": "nsp_test_1",
"password":"password",
"tenant_name":"nsp_tenant_1"
},
{
"username":"nsp_test_2",
"password":"password2",
"tenant_name":"nsp_tenant_2"
}
]
}

Check the deployment

deployment of services created to check whether it is normal, the following are the results
Task execution
Rally is a test unit Task performed, specify Task execution file entry, file or may be json file yaml
The following is the implementation of the form:
rally task start /rally-openstack/samples/tasks/scenarios/nova/boot_ljy.yaml
Frequently used scene
The default template position scene / rally-openstack / samples / tasks / scenarios

Web generated test report
Use rally task report [task_id] --out = [outfile.html] can generate a test report format web
Possible at this time there will be an error to open the html file because report.html file uses some css, js library, these libraries on the google on the site, and therefore will appear so strange phenomenon.
Libs need to report.html which follows four lines in the URL:
<link rel="stylesheet"href="https://cdnjs.cloudflare.com/ajax/libs/nvd3/1.1.15-beta/nv.d3.min.css"> <script type="text/javascript"src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.3/angular.min.js"></script> <script type="text/javascript"src="https://cdnjs.cloudflare.com/ajax/libs/d3/3.4.13/d3.min.js"></script> <script type="text/javascript"src="https://cdnjs.cloudflare.com/ajax/libs/nvd3/1.1.15-beta/nv.d3.min.js"></script>
Replace libs web site can be accessed bootcss static library, as follows:
<link rel="stylesheet"href="http://cdn.bootcss.com/nvd3/1.1.15-beta/nv.d3.css"> <script type="text/javascript"src="http://cdn.bootcss.com/angular.js/1.3.3/angular.min.js"></script> <script type="text/javascript"src="http://cdn.bootcss.com/d3/3.4.13/d3.min.js"></script> <script type="text/javascript"src="http://cdn.bootcss.com/nvd3/1.1.15-beta/nv.d3.min.js"></script>
Then it can open. Or directly to the corresponding row report.html modify the template file out such that the resulting report will automatically replace the web page.
Template file location: /usr/lib/python2.7/site-packages/rally/ui/templates/task/report.html
The above command is successful, you can see files generated Html, Html files can be viewed in a browser. Display of results as follows:
