[mrtg] AW: Re: cpu load

[Wolfgang Vonlanthen]

Hi Andre,

I have Linux SuSe disribution, you can find the program called "w" in /usr/bin (instead in /usr/ucb)



W(1)                Linux Programmer's Manual                W(1) 
                                                                  
NAME                                                              
       w - Show who is logged on and what they are doing.         
                                                                  
SYNOPSIS                                                          
       w - [husfV] [user]                                         
                                                                  
DESCRIPTION                                                       
       w  displays  information  about the users currently on the 
       machine, and their processes.  The header shows,  in  this 
       order,   the  current  time,  how long the system has been 
       running, how many users are currently logged on,  and  the 
       system load averages for the past 1, 5, and 15 minutes.    


with kind regards 

Wolfgang Vonlanthen

Hi,
thank you for your help! I still have a little problem: i don't have anything
like `/usr/ucb/w'. What does this program do?
