Install and configure controller node

This section describes how to install and configure the Telemetry module, code-named ceilometer, on the controller node. The Telemetry module uses separate agents to collect measurements from each OpenStack service in your environment.

To configure prerequisites

Before you install and configure Telemetry, you must install MongoDB, create a MongoDB database, service credentials, and API endpoint.

obs

  1. Enable the Open Build Service repositories for MongoDB based on your openSUSE or SLES version:

    On openSUSE:

    # zypper addrepo -f obs://server:database/openSUSE_13.2 Database

    On SLES:

    # zypper addrepo -f obs://server:database/SLE_12 Database

    Note

    The packages are signed by GPG key 562111AC05905EA8. You should verify the fingerprint of the imported GPG key before using it.

    Install the MongoDB package:

    # zypper install mongodb

rdo

  1. Install the MongoDB package:

    # yum install mongodb-server mongodb

ubuntu

  1. Install the MongoDB package:

    # apt-get install mongodb-server mongodb-clients python-pymongo

obs

  1. Edit the /etc/mongodb.conf file and complete the following actions:
    1. Configure the bind_ip key to use the management interface IP address of the controller node.

      bind_ip = 10.0.0.11
    2. By default, MongoDB creates several 1 GB journal files in the /var/lib/mongodb/journal directory. If you want to reduce the size of each journal file to 128 MB and limit total journal space consumption to 512 MB, assert the smallfiles key:

      smallfiles = true

      You can also disable journaling. For more information, see the MongoDB manual.

    3. Start the MongoDB services and configure them to start when the system boots:

      # systemctl enable mongodb.service
      # systemctl start mongodb.service

rdo

  1. Edit the /etc/mongod.conf file and complete the following actions:
    1. Configure the bind_ip key to use the management interface IP address of the controller node.

      bind_ip = 10.0.0.11
    2. By default, MongoDB creates several 1 GB journal files in the /var/lib/mongodb/journal directory. If you want to reduce the size of each journal file to 128 MB and limit total journal space consumption to 512 MB, assert the smallfiles key:

      smallfiles = true

      You can also disable journaling. For more information, see the MongoDB manual.

    3. Start the MongoDB services and configure them to start when the system boots:

      # systemctl enable mongod.service
      # systemctl start mongod.service

ubuntu

  1. Edit the /etc/mongodb.conf file and complete the following actions:
    1. Configure the bind_ip key to use the management interface IP address of the controller node.

      bind_ip = 10.0.0.11
    2. By default, MongoDB creates several 1 GB journal files in the /var/lib/mongodb/journal directory. If you want to reduce the size of each journal file to 128 MB and limit total journal space consumption to 512 MB, assert the smallfiles key:

      smallfiles = true

      If you change the journaling configuration, stop the MongoDB service, remove the initial journal files, and start the service:

      # service mongodb stop
      # rm /var/lib/mongodb/journal/prealloc.*
      # service mongodb start

      You can also disable journaling. For more information, see the MongoDB manual.

    3. Restart the MongoDB service:

      # service mongodb restart

obs or ubuntu

  1. Create the ceilometer database:

    # mongo --host controller --eval '
      db = db.getSiblingDB("ceilometer");
      db.addUser({user: "ceilometer",
      pwd: "CEILOMETER_DBPASS",
      roles: [ "readWrite", "dbAdmin" ]})'
    
    MongoDB shell version: 2.4.x
    connecting to: controller:27017/test
    {
     "user" : "ceilometer",
     "pwd" : "72f25aeee7ad4be52437d7cd3fc60f6f",
     "roles" : [
      "readWrite",
      "dbAdmin"
     ],
     "_id" : ObjectId("5489c22270d7fad1ba631dc3")
    }

    Replace CEILOMETER_DBPASS with a suitable password.

rdo

  1. Create the ceilometer database:

    # mongo --host controller --eval '
      db = db.getSiblingDB("ceilometer");
      db.createUser({user: "ceilometer",
      pwd: "CEILOMETER_DBPASS",
      roles: [ "readWrite", "dbAdmin" ]})'
    
    MongoDB shell version: 2.6.x
    connecting to: controller:27017/test
    Successfully added user: { "user" : "ceilometer", "roles" : [ "readWrite", "dbAdmin" ] }

    Replace CEILOMETER_DBPASS with a suitable password.

  1. Source the admin credentials to gain access to admin-only CLI commands:

    $ source admin-openrc.sh
  2. To create the service credentials, complete these steps:

    1. Create the ceilometer user:

      $ openstack user create --password-prompt ceilometer
      User Password:
      Repeat User Password:

  1. Generate a random value to use as the telemetry secret:

    $ openssl rand -hex 10
  2. Edit the /etc/ceilometer/ceilometer.conf file and complete the following actions:

    1. In the [database] section, configure database access:

      [database]
      ...
      connection = mongodb://ceilometer:CEILOMETER_DBPASS@controller:27017/ceilometer

      Replace CEILOMETER_DBPASS with the password you chose for the Telemetry module database. You must escape special characters such as ':', '/', '+', and '@' in the connection string in accordance with RFC2396.

    2. In the [DEFAULT] and [oslo_messaging_rabbit] sections, configure RabbitMQ message queue access:

      [DEFAULT]
      ...
      rpc_backend = rabbit
      
      [oslo_messaging_rabbit]
      ...
      rabbit_host = controller
      rabbit_userid = openstack
      rabbit_password = RABBIT_PASS

      Replace RABBIT_PASS with the password you chose for the openstack account in RabbitMQ.

    3. In the [DEFAULT] and [keystone_authtoken] sections, configure Identity service access:

      [DEFAULT]
      ...
      auth_strategy = keystone
      
      [keystone_authtoken]
      ...
      auth_uri = http://controller:5000/v2.0
      identity_uri = http://controller:35357
      admin_tenant_name = service
      admin_user = ceilometer
      admin_password = CEILOMETER_PASS

      Replace CEILOMETER_PASS with the password you chose for the ceilometer user in the Identity service.

      Note

      Comment out any auth_host, auth_port, and auth_protocol options because the identity_uri option replaces them.

    4. In the [service_credentials] section, configure service credentials:

      [service_credentials]
      ...
      os_auth_url = http://controller:5000/v2.0
      os_username = ceilometer
      os_tenant_name = service
      os_password = CEILOMETER_PASS
      os_endpoint_type = internalURL
      os_region_name = RegionOne

      Replace CEILOMETER_PASS with the password you chose for the ceilometer user in the Identity service.

    5. In the [publisher] section, configure the telemetry secret:

      [publisher]
      ...
      telemetry_secret = TELEMETRY_SECRET

      Replace TELEMETRY_SECRET with the telemetry secret that you generated in a previous step.

    obs

    1. In the [collector] section, configure the dispatcher:

      [collector]
      ...
      dispatcher = database
    2. (Optional) To assist with troubleshooting, enable verbose logging in the [DEFAULT] section:
