如何在Python中禁用来自第三方模块的INFO日志记录

Question

我正在使用Python查询Serf集群，但我想抑制来自Serf的INFO数据。我试图覆盖它，以便它只打印WARNING消息，但它拒绝接受它。

输出：

01-04 14:57 root         INFO     Connecting to cluster
01-04 14:57 serf-rpc-client INFO     will connect to [('myhost.localdomain.local', 7373, {})]
01-04 14:57 serf-rpc-client INFO     trying to connect to myhost.localdomain.local:7373
01-04 14:57 serf-rpc-client INFO     connected to myhost.localdomain.local:7373
01-04 14:57 serf-rpc-client INFO     trying to request command: <RequestHandshake: handshake, 0, {'Version': 1}>
01-04 14:57 serf-rpc-client INFO     trying to request command: <RequestAuth: auth, 1, {'AuthKey': 'thundercats'}>
01-04 14:57 serf-rpc-client INFO     trying to request command: <RequestMembers: members, 2, {'Status': 'failed'}>
01-04 14:57 serf-rpc-client INFO     successfully handshaked
01-04 14:57 serf-rpc-client INFO     successfully authed
01-04 14:57 root         INFO     myhost123.localdomain.local has left the cluster

记录代码

logging.basicConfig(level=logging.INFO,
                format='%(asctime)s %(name)-12s %(levelname)-8s %(message)s',
                datefmt='%m-%d %H:%M',
                filename='/var/log/ocd_watcher.log',
                filemode='w')

serf_logger = logging.getLogger('serf')
serf_logger.setLevel(logging.WARNING)

console_handler = logging.StreamHandler()
console_handler.setLevel(logging.INFO)
console_handler.setFormatter(default_formatter)

logger = logging.getLogger()
logger.addHandler(console_handler)
logger.addHandler(serf_logger)

记录器名称为serf-rpc-client，因此应该可以使用

serf_logger = logging.getLogger('serf-rpc-client')
serf_logger.setLevel(logging.WARNING)
