从syslog.conf迁移到syslogng.conf

Question

我正在将Solaris框从of移动到syslog-ng，因为syAdd.1-d的Solaris版本删除了日志上的原始源主机名。我正在查看syslogng.conf文档，但不确定我是否完全理解它。我们有一个相对简单的syslog.conf，我希望那里的一个syslog-ng专家能告诉我如何将它“转换”成一个可行的syslogng.conf？

一旦您了解了它的配置文件的结构，syslog就非常直接(但是非常冗长)。在像您这样简单的安装中，您现在需要知道的是，您必须配置源、过滤器和目的地。我不知道您正在运行哪个版本的syslog-ng，但是这里有一个用于3.0.x的版本(也适用于最近的版本)：

@version 3.0

# syslog source
source s_sys { sun-streams ("/dev/log" door("/var/run/syslog_door")); };

# use this instead if you receive logs from network:
# source s_sys { udp ();
#                sun-streams ("/dev/log" door("/var/run/syslog_door")); };

# destinations
destination d_sysmsg { file ("/dev/sysmsg"); };
destination d_messages { file ("/var/adm/messages"); };
destination d_ncolog { file ("/var/log/ncolog"); };
destination d_nimitz { udp ("nimitz"); };
destination d_auth { file ("/var/log/authlog"); };
destination d_syslog { file ("/var/log/syslog"); };
destination d_users { usertty ("*"); };

# filters
filter f_emerg { priority (emerg); };
filter f_sysmsg { priority (err..emerg) or
                  (facility (kern) or facility (auth)) and priority (notice..emerg); };
filter f_messages { priority (err..emerg) or
                    facility (kern) or
                    facility (daemon) and priority (notice..emerg) or
                    facility (mail) and priority (crit..emerg); };
filter f_local7 { facility (local7); };
filter f_audit { facility (13); };
filter f_mail { facility (mail); };

# log paths
log { source (s_sys); filter (f_emerg); destination (d_users); };
log { source (s_sys); filter (f_sysmsg); destination (d_sysmsg); };
log { source (s_sys); filter (f_messages); destination (d_messages); };
log { source (s_sys); filter (f_local7); destination (d_ncolog); destination (d_nimitz); };
log { source (s_sys); filter (f_audit); destination (d_ncolog); destination (d_nimitz); };
log { source (s_sys); filter (f_mail); destination (d_syslog); };

我想我涵盖了所有的一切，除了“如果”的部分。如果您的主机没有在本地保存日志，即它不是LOGHOST，则必须添加另一个目的地

destination d_loghost { udp ("loghost"); };

并将邮件的日志路径更改为

log { source (s_sys); filter (f_mail); destination (d_loghost); };
