前提：在测试过程需要关注多个 tomcat 的多个实时日志
老方式：打开多个 ssh 回话，分别 tail -f 不同路径下的不同日志
问题：虽然输命令也不是很慢，但重复的输命令也麻烦啊；不知道为什么 xshell 一天会断掉大概两次连接，就得再输命令打开日志
一种解决方式：网上搜了才发现，可以 tail -f 多个日志，这样就可以同时查看多个日志了；但是仍存在问题，有些操作会刷出来很多日志，看着有点不方便；tail -f 后写多个路径也有多，最好这一步也省去
问题：有没有可以便捷实时查看多个日志的方法或者工具
log.io 推荐给你
额，其实 tail -f 多个日志也差不多能满足我的需求了，就是想找个再好用的方法。。。
是个点子，然而已有技能不足以支撑我搞起这个网站，回头我细细看看，当前想直接用现成的
刚发现 xshell 有分屏的功能，虽然仍没有解决我的问题，但这个功能也很好用啊
用 perl 写过一个实时监控文件变化的。
用的是 File::Tail 这个模块。
其他语言应该也有类似的实现。
log.io 推荐给你

同样遇到这个问题，google 有说切换用户的，有说降低 node 版本的。难道 node 的版本这么弱鸡，不向下兼容？之前安装 stf 也是一堆编译错误，降了 node 版本才搞定的。node 的包管理机制真是蛋疼。
。。。我折腾了好久，试了了好多个版本，用 v4.9.1 这个版本才行。。。
