Busy Server

Even though servers do have their “protection” against overload throwing a 503 error, at the time when this happen, server can be really overloaded already. This plugin checks the actual CPU load and if higher than specified (by default 2 per every core), displays an error message.

Very simple checking is used and by no means is this a replacement to proper load balancing. Can be useful though, especially when your server system is undergoing a tuning or heavy maintenance, is under weak attack, etc. and you don’t want to disable the site completely.

Currently only Linux servers are supported ( = tested), other UNIX systems should work as well.

Roadmap:

• Cache detection (if page is cached, serve it regardless the load)

• Support for Win servers

• Test server compatibility

• Storing settings outside of database for speed improvement
