Please note that ceilometer uses openstack-common extensively, which requires that the other parameters are set appropriately. For information we are listing the configuration elements that we use after the ceilometer specific elements. If you use sql alchemy, its specific paramaters will need to be set. =============================== ==================================== ============================================================== Parameter Default Note =============================== ==================================== ============================================================== nova_control_exchange nova Exchange name for Nova notifications glance_control_exchange glance Exchange name for Glance notifications cinder_control_exchange cinder Exchange name for Cinder notifications neutron_control_exchange neutron Exchange name for Neutron notifications metering_secret change this or be hacked Secret value for signing metering messages metering_topic metering the topic ceilometer uses for metering messages sample_source openstack The source name of emited samples control_exchange ceilometer AMQP exchange to connect to if using RabbitMQ or Qpid database_connection mongodb://localhost:27017/ceilometer Database connection string metering_api_port 8777 The port for the ceilometer API server reseller_prefix AUTH\_ Prefix used by swift for reseller token =============================== ==================================== ============================================================== Service polling authentication ============================== The following options must be placed under a [service_credentials] section and will be used by Ceilometer to retrieve information from OpenStack components. =============================== ==================================== ============================================================== Parameter Default Note =============================== ==================================== ============================================================== os_username ceilometer Username to use for openstack service access os_password admin Password to use for openstack service access os_tenant_id Tenant ID to use for openstack service access os_tenant_name admin Tenant name to use for openstack service access os_auth_url http://localhost:5000/v2.0 Auth URL to use for openstack service access os_endpoint_type publicURL Endpoint type in the catalog to use to access services =============================== ==================================== ============================================================== Keystone Middleware Authentication ================================== The following table lists the Keystone middleware authentication options which are used to get admin token. Please note that these options need to be under [keystone_authtoken] section. =============================== ==================================== ============================================================== Parameter Default Note =============================== ==================================== ============================================================== auth_host The host providing the Keystone service API endpoint for validating and requesting tokens auth_port 35357 The port used to validate tokens auth_protocol https The protocol used to validate tokens auth_uri auth_protocol://auth_host:auth_port The full URI used to validate tokens admin_token Either this or the following three options are required. If set, this is a single shared secret with the Keystone configuration used to validate tokens. admin_user User name for retrieving admin token admin_password Password for retrieving admin token admin_tenant_name Tenant name for retrieving admin token signing_dir The cache directory for signing certificate certfile Required if Keystone server requires client cert keyfile Required if Keystone server requires client cert. This can be the same as certfile if the certfile includes the private key. =============================== ==================================== ============================================================== SQL Alchemy =========== ========================== ==================================== ============================================================== Parameter Default Note ========================== ==================================== ============================================================== sql_connection_debug 0 Verbosity of SQL debugging information. 0=None, 100=Everything sql_connection_trace False Add python stack traces to SQL as comment strings sql_idle_timeout 3600 timeout before idle sql connections are reaped sql_max_retries 10 maximum db connection retries during startup. (setting -1 implies an infinite retry count) sql_retry_interval 10 interval between retries of opening a sql connection mysql_engine InnoDB MySQL engine to use sqlite_synchronous True If passed, use synchronous mode for sqlite ========================== ==================================== ============================================================== HBase =================== To configure HBase as your database backend: 1. To install an HBase server, for pure development purpose, you can just download the HBase image from Cloudera and get it up and running. Then the quickest way to check it is to run the ``HBase shell`` and try a ``list`` command which would return the list of the tables in your HBase server: :: $ ${HBASE_HOME}/bin/hbase shell hbase> list .. note:: This driver has been tested against HBase 0.92.1/CDH 4.1.1, HBase 0.94.2/CDH 4.2.0, HBase 0.94.4/HDP 1.2 and HBase 0.94.5/Apache. Versions earlier than 0.92.1 are not supported due to feature incompatibility. 2. A few HBase tables are expected by Ceilometer. To create them, run the following: :: $ ${HBASE_HOME}/bin/hbase shell hbase> create 'project', {NAME=>'f'} hbase> create 'user', {NAME=>'f'} hbase> create 'resource', {NAME=>'f'} hbase> create 'meter', {NAME=>'f'} 3. This driver is implemented to use HBase Thrift interface so it's necessary to have the HBase Thrift server installed and started. When you have HBase installed, normally, HBase thrift server is turned on by default. If it's not, turn it on by running command ``hbase thrift start``. The implementation uses `HappyBase`_ which is a wrapper library used to interact with HBase via Thrift protocol, you can verify the thrift connection by running a quick test from a client: .. _HappyBase: http://happybase.readthedocs.org/en/latest/index.html# :: import happybase conn = happybase.Connection(host=$hbase-thrift-server, port=9090, table_prefix=None) print conn.tables() # this returns a list of HBase tables in your HBase server 4. The parameter "database_connection" needs to be configured to point to the Hbase Thrift server. =========================== ==================================== ============================================================== Parameter Value Note =========================== ==================================== ============================================================== database_connection hbase://$hbase-thrift-server:9090 Database connection string =========================== ==================================== ============================================================== .. note:: If you are changing the configuration on the fly, you will need to restart the Ceilometer services that use the database to allow the changes to take affect, i.e. the collector and API services. General options =============== The following is the list of openstack-common options that we use: =========================== ==================================== ============================================================== Parameter Default Note =========================== ==================================== ============================================================== default_notification_level INFO Default notification level for outgoing notifications default_publisher_id $host Default publisher_id for outgoing notifications bind_host 0.0.0.0 IP address to listen on bind_port 9292 Port numver to listen on port 5672 Rabbit MQ port to liste on fake_rabbit False If passed, use a fake RabbitMQ provider publish_errors False publish error events use_stderr True Log output to standard error logfile_mode 0644 Default file mode used when creating log files log_dir Log output to a per-service log file in named directory log_file Log output to a named file log_format date-time level name msg Log format log_date_format YYYY-MM-DD hh:mm:ss Log date format log_config Logging configuration file used.
