Looking for input on how to solve the following problem. My ColdFusion 9 app has a simple logger that writes text to a file. On my dev machine, the file is local so I can use either 'tail -f' or CFB's TailView to watch it. I'd like a tool to watch it when it's deployed on the production server. The catch: production is at a shared CF hosting provider which doesn't allow RDS file access or a directory-watcher gateway. I'm wondering about a page with a meta refresh tag or if I want to get more fancy, something AJAXy to the same effect. Thoughts? Any tools that already exist for this?

I may experiment with this but am hoping there is something out there "more complete" : following a log file over http

您可以使用以下 PHP 脚本：

<?php
header("Content-Type: text/plain");
set_time_limit(0);
passthru("tail -F -n +0 log.txt");
?>

以下伪代码受此Java 解决方案的启发，根本未经测试：

if (NOT structKeyExists(application, "log") {
    application.log = fileOpen('log.txt', 'read')
}

while(NOT FileisEOF(application.log))  {
    writeOutput(fileReadLine(application.log) & "<br/>");
}

将其放在具有元刷新的页面上，我认为您可能正在开展业务。

我为我的用例 ( tail.sh )创建了以下 bash 脚本

它使用“lynx”获取文件列表，从中获取所需的文件大小，并在无限循环中尝试获取文件的一部分

I know it's pretty old school, but have you considered logging to a database? If you timestamp the log entries in the table you could use HTTP Caching headers to communicate to the server what new data you should see.
