Jai,
As far as I know, Ganglia is only tested (and working) with php4 for now.
This is probably the cause of the php errors you get and why you can't
see the correct graphs.
I would suggest trying again with php4.
Kind regards,
- Ramon.

Thanks Roman,
I checked all this,
I have rrdtool, php-gd
added extension-gd.so in php.ini
I can see the graphs, but they are not the right graphs. The graph I
see is only load_one information over all the nodes..
Here are some error in my http_ error_log file
BTW I am using php5.0, can that be any issue..

Hi Jai,
You need additional software/packages to get the graphs and pie
charts working.
For the graphs you need rrdtool:
rrdtool 1.0.49-1
librrd0 1.0.49-1
For the pie chart you need libgd and the php plugin of it:
libgd2-xpm 2.0.33-1.1
php4-gd 4.3.10-16
(package names and versions based upon Debian sarge)
The later php gd plugin requires that you add this line to php.ini:
extension=gd.so
This should do the trick.
Kind regards,
- Ramon.

Hello,
I am trying to configure Ganglia monitoring system for our cluster.
Its seems to be working all the port and everything look fine, Here
are my configuration files
**************************************************
*Gmetad.conf*
I added these two lines in this file
Server1 is running both gmond and gmetad services
data_source "Our Cluster Name" Server1:8649 Server2:8649
server3:8649 server4:8649 Server5:8649
gridname "Our Grid Name"
*Gmond.conf *File which is same on all the nodes
/* This configuration is as close to 2.5.x default behavior as possible
The values closely match ./gmond/metric.h definitions in 2.5.x */
globals {
setuid = yes
user = nobody
# debug_level = 10
cleanup_threshold = 300 /*secs */
}
/* If a cluster attribute is specified, then all gmond hosts are
wrapped inside
* of a <CLUSTER> tag. If you do not specify a cluster tag, then all
<HOSTS> will
* NOT be wrapped inside of a <CLUSTER> tag. */
cluster {
name = "Our Cluster Name"
owner = "Our Grid Name"
}
/* Feel free to specify as many udp_send_channels as you like. Gmond
used to only support having a single channel */
udp_send_channel {
# mcast_join = 239.2.11.71
* host = server1*
port = 8649
}
/* You can specify as many udp_recv_channels as you like as well. */
udp_recv_channel {
port = 8649
acl {
default = "allow"
access {
ip = 192.168.240.0
mask = 32
action = "allow"
}
}
}
/* You can specify as many tcp_accept_channels as you like to share
an xml description of the state of the cluster */
tcp_accept_channel {
port = 8649
acl{
default="allow"
access {
ip= 192.168.240.0
mask = 32
action = "allow"
}
}
}
/* The old internal 2.5.x metric array has been replaced by the
following
collection_group directives. What follows is the default behavior
for
collecting and sending metrics that is as close to 2.5.x behavior as
possible. */
/* This collection group will cause a heartbeat (or beacon) to be
sent every
20 seconds. In the heartbeat is the GMOND_STARTED data which
expresses
the age of the running gmond. */
collection_group {
collect_once = yes
time_threshold = 20
metric {
name = "heartbeat"
}
}
/* This collection group will send general info about this host
every 1200 secs.
This information doesn't change between reboots and is only
collected once. */
collection_group {
collect_once = yes
time_threshold = 1200
metric {
name = "cpu_num"
.... Default Collection Group, I did not make any change in that.
***************************************************************************
Started gmetad and gmond, Everything seems fine so far, it created
rrds in /var/ling/ganglia/rrd/our cluster name/server* directory.
Now when I go on the web to see the graphs, all the graphs looks
same. I click on different links, but I get the same graph every
time. pie chart does not show up, Can some body suggest me what I
might be missing. I dont see, CPU, Memory and Network usage graphs.
DO I have to do anything in web-front-end configuration. See the
image below
I am using These packages..
ganglia-gmond-3.0.1-1
ganglia-monitor-core-lib-2.5.7-1
ganglia-gmetad-3.0.1-1
ganglia-web-3.0.1-1
2.6.11 Kernel.
I can provide more information if that can help you understanding
the problem.
Thanks you so much,
