Install the Watcher client

You can install the Watcher CLI with the following command:

pip install python-watcherclient

Configuration

Create a creds file containing your Openstack credentials:

export OS_IDENTITY_API_VERSION=3
export OS_AUTH_URL=http://<your-keystone-server>:5000/v3
export OS_PROJECT_DOMAIN_ID=default
export OS_USER_DOMAIN_ID=default
export OS_USERNAME=admin
export OS_PASSWORD=<your-password>
export OS_PROJECT_NAME=<your-project-name>

Source these credentials into your current shell session:

# source creds

You should be able to launch the following command which gets the list of previously created Audit Templates:

# watcher audit-template-list
+------+------+
| UUID | Name |
+------+------+
+------+------+

You can view the entire list of available Watcher commands and options using this command:

# watcher help

Troubleshootings

If any watcher command fails, you can obtain more details with the --debug option :

# watcher --debug audit-template-list

Install the openstack CLI :

# pip install python-openstackclient

Make sure that your Openstack credentials are correct. If so, you should be able to verify that the watcher user has been declared in your Openstack keystone :

# openstack user list

and that the watcher endpoints have been declared as well :

# openstack endpoint list
