Thanks for your time, I checked what you told me
And made some changes, but I'm still getting the same problem.
>>1) Check the "rrd_rootdir" option in gmetad.conf and make sure it
points
>>to the place you want the rrd files to be written.
I'm using the default round-robing folder
#-----------------------------------------------------------------------
--------
# Where gmetad stores its round-robin databases
# default: "/var/lib/ganglia/rrds"
#rrd_rootdir "/usr/local/rrdtool-1.2.23/share/rrdtool"
>>2) Check the permissions on that dir to make sure that gmetad can
write
>>to it.
Permissions are right, own by ganglia user, user is especify in the
gmetad.conf
drwxr-xr-x 3 ganglia ganglia 4096 2007-07-11 16:57 ganglia
>>3) Run gmetad for a bit. Then look in the rrd_rootdir to see if
gmetad

Nothing is created in /var/lib/ganglia/rrds/_SummaryInfo/ folder
>>4) For the web frontend, make sure conf.php defines $gmetad_root and
>>$rrds properly. Make sure that $rrds matches the value of rrd_rootdir

This is my /var/www/ganglia/conf.php file
# Where gmetad stores the rrd archives.
$gmetad_root = "/var/lib/ganglia";
#$gmetad_root = "/usr/local/rrdtool-1.2.23/share/rrdtool";
$rrds = "$gmetad_root/rrds";
# Leave this alone if rrdtool is installed in $gmetad_root,
# otherwise, change it if it is installed elsewhere (like /usr/bin)
#define("RRDTOOL", "/usr/local/rrdtool-1.2.23/bin/rrdtool");
define("RRDTOOL", "/usr/bin/rrdtool");
#define("RRDTOOL", "/var/lib/ganglia"); # itried
both
>>5) In conf.php, make sure the define("RRDTOOL", ...) line points to
the
>>location of the correct rrdtool binary.
I tried both paths.
define("RRDTOOL", "/usr/bin/rrdtool");
#define("RRDTOOL", "/var/lib/ganglia"); # itried
both
Also, I forgot to mention that this message are in my /var/log/syslog
Jul 17 12:46:00 apprep /usr/sbin/gmetad[23745]: poll() timeout for
[serenity] data source after 0 bytes read

Thanks for you prompt responses.
