request - The request that has been processed.
nbytes - The number of emited bytes in reply's body.
duration - The processing time of the request.
o getServerLoad 
 public int getServerLoad()
Get the current server load.

Returns:
A number between 1 and 4.

 public long getMeanRequestTime()
Get the mean request processing time.

Returns:
The average time to process a request.
o getMaxRequestTime 
 public long getMaxRequestTime()
Get the max request processing time.

Returns:
A long giving the maximum duration for a request.
o getMaxRequestURL

A String giving the URL of the corresponding request, or null if no request has been processed yet.
o getMinRequestTime 
 public long getMinRequestTime()
Get the min request processing time.

Returns:
A long giving the minimum request processing time.
o getMinRequestURL 
 public URL getMinRequestURL()
Get the URL of the request that took the smallest time to be processed.
