Hi there, I’ve been using log_server_status to monitor the
behaviour of my apache servers and am getting some odd behaviour between Linux
and solaris. On solaris if I set the $server variable to a non-existent name ,
such as www.foo.com, then the script fails to
connect to the running webserver, which is exactly what I expect. In the linux
implementation (built under SLES10SP2) if I leave the $server variable set to
localhost it also fails as I expect as I don’t have a webserver running
on 127.0.0.1. However if I set the variable to anything other than localhost,
e.g “notlocalhost” or any other name other than that of my
listening server then the script connects and reports back properly. Has anyone
come across this before???? Obviously it makes my life easy as on the linux
servers I can deliver a generic script with “notlocalhost”
configured as the server name and I know it will connect and report back okay.
It just doesn’t work as you would expect. Ie. A duff name should result
in a no-connection. Also the standard delivered log_server_status script is
faulty for the following reason: The request variable comes configured as “$request =
"/status/?auto";” , whereas it should be “$request =
"/server-status/?auto";” Also the script is limited on what it will report so it
would be better to modify the script output to report more of what
“/server-status?auto” gives you. I have made the following changes
to report more and to format the outputted file better to allow graphing within
the likes of excel. Date Format: Change: $date = $year . `date
+%m%d:%H%M%S`; To: $date = $year .
`date +%m%d:%H.%M.%S`; Change: while (<S>) {
$requests=$1 if ( m|^BusyServers:\ (\S+)|);
$idle=$1 if ( m|^IdleServers:\ (\S+)|);
$number=$1 if ( m|sses:\ (\S+)|);
$cpu=$1 if (m|^CPULoad:\ (\S+)|); } print OUT
"$time:$requests:$idle:$number:$cpu\n"; To: 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"; Hope this helps someone out, but would there be any mileage
in getting the delivered script to suit the above format and also to apply the
fix to the request variable.
