Hello,

I get “Checking plugin…” all the time in the log and would like to  
disable it. I figure out that it comes from Engines.logger and want to  
set the logging level to info in stead of debug. How can I do this?  
Thaks!

Franck

To minimize engines polluting our logs, we just changed the logger for  
the engines plugin like this:

In engines.rb, update the logger method:

```
def logger
  #RAILS_DEFAULT_LOGGER
  Logger.new(RAILS_ROOT + "/log/engines.log")
end

```

And then create an “engines.log” under your /log directory. Now all  
engines related logging will be directed to that file instead of your  
development.log.

Probably better to do this:

Logger.new(File.join(RAILS\_ROOT, “log”, “engines.log”))

But how to use it then? Wouldn’t it instantiate a new Logger instance  
every  
time I call it?

def some\_foo\_method

# I want to log something, I call the logger method

logger.debug(“I did something”)  
end

So, the “logger” method instantiates a new Logger instance every time.  
It is not good to have dozens logger instances in memory. How to avoid  
it? How to instantiate once and then just take only that one instance?
