跟踪多个文件

from sshtail import SSHMultiTailer

    '4.3.2.1': ['/path/to/log3.log'],
})

# will run until it receives SIGINT, after which it will
# automatically catch the exception, disconnect from the
# remote hosts and perform cleanup

for host, filename, line in tailer.tail():
    print "%s:%s - %s" % (host, filename, line)

使用自定义私钥

from sshtail import SSHMultiTailer, load_dss_key

# if no path's specified for the private key file name,
# it automatically prepends /home/<current_user>/.ssh/
# and for RSA keys, import load_rsa_key instead.

tailer = SSHMultiTailer({
        '1.2.3.4': ['/path/to/log1.log', '/path/to/log2.log'],
        '4.3.2.1': ['/path/to/log3.log'],
    },
    private_key=load_dss_key('identity'))

for host, filename, line in tailer.tail():
    print "%s:%s - %s" % (host, filename, line)
