What is IIS

As a result, there are many more units of IIS being used as Web server software today. By default, these servers must allow public access to their resources. But we have found that many units spend even more time defending and providing web services than they do on the defensive.

As a system O M engineer, I think it is a daily task to view and analyze LINUX system logs. However, after a long time, I find that every time I view the site logs, I have to go to the background one by one, several servers can do this, but if you manage hundreds of thousands of online servers, this method is too slow.
Later I thought that I could not have a log server to manage logs in a centralized manne
