RE: Information in mod_status to text file (Apache Users)

For example, the standard script comes with the following:

while (<S>) {

$requests=$1 if ( m|^BusyWorkers:\ (\S+)|);

$idle=$1 if ( m|^IdleWorkers:\ (\S+)|);

$number=$1 if ( m|Total Accesses:\ (\S+)|);

$cpu=$1 if (m|^CPULoad:\ (\S+)|);

}

print OUT "$time,$requests,$idle,$number,$cpu\n";

I modified this to get the following data:

while (<S>) {

$accesses=$1 if ( m|^Total Accesses:\ (\S+)|);

$kbytes=$1 if ( m|^Total kBytes:\ (\S+)|);

$cpuload=$1 if ( m|^CPULoad:\ (\S+)|);

$uptime=$1 if ( m|Uptime:\ (\S+)|);

$reqpersec=$1 if (m|^ReqPerSec:\ (\S+)|);

$bytespersec=$1 if (m|^BytesPerSec:\ (\S+)|);

$bytesperreq=$1 if (m|^BytesPerReq:\ (\S+)|);

$busyworkers=$1 if (m|^BusyWorkers:\ (\S+)|);

$idleworkers=$1 if (m|^IdleWorkers:\ (\S+)|);

}

print OUT "$time,$accesses,$kbytes,$cpuload,$uptime,$reqpersec,$bytespersec,$bytesperreq,$busyworkers,$idleworkers\n";

So its very useful for seeing if you run out of resources and what your throughput is looking like.

Why not have a look at “log_server_status” , google it..

It’s a useful perl script that can be used to connect to the server and output the metrics into a logfile for then graphing against.

It comes with a very basic set of reports but its quite easy to modify to collect further fields of information to see what the statistical behaviour of the webserver is.
