Look at the man page (UNIX) for uptime, and that explains the three metrics as - they are the ... load averages for the past 1, 5, and 15 minutes.
Unfortunately, that still begs the explanation to the question - What is the load? According to Dr. Neil Gunther, a recognized expert on performance management and capacity planning "The Load Average triplet is intended to provide you with some kind of information about how much work has been done on the system (especially on CPU) in the recent past (1 minute), the past (5 minutes) and the distant past (15 minutes)". Dr. Gunther's fact findings on the same subject can be found at the following URLs: http://www.teamquest.com/html/gunther/ldavg1.shtml & http://www.teamquest.com/html/gunther/ldavg2.shtml BR, N ---------------------------------------------- On Wed, 27 Oct 2004 Vikram Mandal wrote : > >----- Original Message ----- From: "Kishore Bhargava" <[EMAIL PROTECTED]> >To: "The Linux-Delhi mailing list" <[EMAIL PROTECTED]> >Sent: Wednesday, October 27, 2004 12:20 AM >Subject: Re: [ilugd] Getting system load and performance infomation > > >>>On Mon, 25 Oct 2004 Vikram Mandal wrote : >>> >>>>Hi, >>>> >>>>I need to display information about the "system load and performance" of Red Hat >>>>Linux and FreeBSD using PHP script. >>>> >> >>Here's a simple way: >> >>http://phpsysinfo.sourceforge.net/ >> > >Thanks, but the above srcipt needs access to /proc files which is not posssible since >php srcipts running under a web server does not have access to system files. > >BTW, do you know what "Load Averages 0.16 0.26 0.12 " means?
