we know ceilometer use tooz to implement ha, so we can found the answer in tooz
First, tooz will parse the backendurl by netutils.urlsplit:
> parsedurl = "">url)Then, backend driver will be found by the url scheme, for example in my situation, memcached
driver.DriverManager( namespace=TOOZ_BACKENDS_NAMESPACE, name=parsed_url.scheme, invoke_on_load=True, invoke_args=(member_id, parsed_url, options)).driver- Finally , the MemcachedDriver will be initialed as below
def __init__(self, member_id, parsed_url, options): super(MemcachedDriver, self).__init__() options = utils.collapse(options) self._options = options self._member_id = member_id self._joined_groups = set() self._executor = utils.ProxyExecutor.build("Memcached", options) self.host = (parsed_url.hostname or "localhost", parsed_url.port or 11211) default_timeout = options.get('timeout', self.DEFAULT_TIMEOUT) self.timeout = int(default_timeout) self.membership_timeout = int(options.get( 'membership_timeout', default_timeout)) self.lock_timeout = int(options.get( 'lock_timeout', default_timeout)) self.leader_timeout = int(options.get( 'leader_timeout', default_timeout)) max_pool_size = options.get('max_pool_size', None) if max_pool_size is not None: self.max_pool_size = int(max_pool_size) else: self.max_pool_size = None self._acquired_locks = []
So, I set the backendurl as "memcached://127.0.0.1:11211"
You can find your answer here: tooz backend driver code
Hope this will help you!
