------截止到现在,28日的信息一点都没有,我昨天13:53重启过syslog.
大家帮忙分析一下是什么原因导致无法写入messages? 难道系统没有任何问题?

检查 syslog 运行情况，看看空间还够不。

我用logger 可以把信息写入到/var/log/messages 中? 我有个疑惑,messages中时间戳是连续的吗?

还是没有人回答俺呀...
如果系统没有问题的话,是不是也不会去更新messages

这当然要看具体情况，如果是没有触发日志级别的问题，自然不会有日志记录。这不代表你的syslog有问题。

所以我想看看，比如说你重启一下network，看看有否日志记录。如果这个操作没有日志记录，那么syslog会有问题了。
