这是IBM基于原生的drain进行的升级，测试一下，很简单的提取日志模板

代码

from drain3.drain import Drain, LogCluster

model = Drain()
entries = str.splitlines(
    """
    Dec 10 07:07:38 LabSZ sshd[24206]: input_userauth_request: invalid user test9 [preauth]
    Dec 10 07:08:28 LabSZ sshd[24208]: input_userauth_request: invalid user webmaster [preauth]
    Dec 10 09:12:32 LabSZ sshd[24490]: Failed password for invalid user ftpuser from 0.0.0.0 port 62891 ssh2
    Dec 10 09:12:35 LabSZ sshd[24492]: Failed password for invalid user pi from 0.0.0.0 port 49289 ssh2
    Dec 10 09:12:44 LabSZ sshd[24501]: Failed password for invalid user ftpuser from 0.0.0.0 port 60836 ssh2
    Dec 10 07:28:03 LabSZ sshd[24245]: input_userauth_request: invalid user pgadmin [preauth]
    """
)

for entry in entries:
    cluster, change_type = model.add_log_message(entry)
    print(cluster.get_template())

输出
