有没有使用贝叶斯算法或其他学习算法的日志分析器？我找到了尾部但版本号（0.2）并没有给出良好的前景。

你可以看看crm114。它通常用于垃圾邮件，但也可以针对其他内容，例如信息防火墙. 它可以安装在 Debian 中：
Description: versatile classifier for e-mail and other data
CRM114, the Controllable Regex Mutilator, is a system to examine incoming
e-mail, system log streams, data files, or other data streams, and to sort,
filter, or alter the incoming files or data streams however the user
desires. Criteria for categorization of data can be by satisfaction of
regular expressions, by sparse binary polynomial matching with a Bayesian
Chain Rule evaluator, or by other means.
.
CRM114 is not just another drop-in spam-filtering system; its Sparse
Binary Polynomial Hashing methods give it the power to develop highly
accurate Bayesian filters on very little training.
.
CRM114 is compatible with SpamAssassin or other spam-flagging software; it
can also be pipelined in front of or behind procmail. CRM114 is also useful
as a syslog or firewall log filter, to flag up important events but ignore
the ones that aren't meaningful.
.
For mail filtering, installing metamail or mew-bin packages is
recommended in order to have tools to decode MIME attachments.
