Hi Antonio,
Thanks much for your response. I now ran /usr/sbin/update-rc.d -f gmond
defaults and
/usr/sbin/update-rc.d -f gmetad defaults, which initially gave me error:
update-rc.d: /etc/init.d/gmond: file does not exist. The init script was in
/etc/rc.d/init.d/. Then I copied it to /etc/init.d/gmond. Now the update-rc.d
went fine .
I cannot view the web interface when I point to http://ip_address/ganglia/
and I get The server at ip_address is taking too long to respond.
Here are some relevant information:
A) I start gmond by "/usr/sbin/gmond" when I do a telnet EC2Ip_address 8649,
it gives
<HOST NAME=EC2Ip_address IP="10.251.86.192" REPORTED="1291666741" TN="30"
TMAX="20" DMAX="0" LOCATION=EC2Ip_address GMOND_STARTED="1291666621">
B) /usr/sbin/gmond -d 10 gives me this:
Got a heartbeat message 1291666768

....and goes on
C) /usr/sbin/gmetad -d 10 gives me this

ttl = 1
}
udp_recv_channel {
port = 8666
family = inet4
}
And gmetad.conf has
data_source "MyCluster" ipaddress:8649
Any help on this would be highly appreciated!.
Thanks,

Hey, Mike,
2010/12/5 Mike <[email protected]>
Hi all,
I am trying to get Ganglia run on Ubuntu instance. I built the version 3.1.7
from source. I compiled the source and libs were installed in
/etc/ganglia/lib64/ganglia/
I used the command: ./configure --prefix=/etc/ganglia --with-gmetad
--sysconfdir=/etc/ganglia && make && make install , and everything went fine.
Ichanged the GMOND in gmond/gmond.init to GMOND=/etc/ganglia/sbin/gmond, and
changed GMETAD in gmetad/gmetad.init to GMETAD=/etc/ganglia/sbin/gmetad
1. I have copied the gmond/gmond.init from the build directory to
/etc/rc.d/init.d/gmond and when I start gmond using the command
/etc/rc.d/init.d/gmond start
I get the following error.
.: 9: Can't open /etc/rc.d/init.d/functions
Also I copied gmetad/gmetad.init to /etc/rc.d/init.d/gmetad and starting it
also fails with the above error.
What is expected for /etc/rc.d/init.d/functions ? by these scripts.
When I try something like "gmond -d 1" to start the gmond in foreground it
gives a message that :
[PYTHON] Can't open the python module path
/etc/ganglia/lib64/ganglia/python_modules. Module python_module failed to
initialize.
In this case, you have to put gmond and gmetad in the startup applications. You
can do this with:
$ sudo updatedb-rc.d -f gmond defaults
$ sudo updatedb-rc.d -f gmetad defaults
The other thing can be solved creating this directory or comment the line that
searches it in /etc/ganglia/gmond.conf. I'm not sure if it's necessary but the
owner of this folder is 'nobody' in my system. I recommend this order:
$ sudo mkdir -p /etc/ganglia/lib64/ganglia/python_modules
2. Also I am running an EC2 instance, so while making the changes in the conf
files,
In the gmetad.conf I made foll changes:
a. data_source "MyCluster" 'internalIP of the instance' ( or should I add
external IP of the instance?)
b. What should I set for User gmetad will setuid to (defaults to
"nobody"). My rrd directory is at /var/lib/ganglia/rrds and is owned by
"root".So
should I set the user here as "root"?
In
the gmond.conf I have the foll:
cluster {
name = "MyCluster"
owner = "MyOwner"
latlong = "unspecified"
url = "unspecified"}
host { location = "unspecified"} (again what should go in here???)
udp_send_channel {
mcast_join = 239.2.11.71
port = 8649
ttl = 1}
udp_recv_channel {
mcast_join = 239.2.11.71
port =
8649
bind = 239.2.11.71}
tcp_accept_channel {
port = 8649}
All other conf paremeters are unchanged.
Please help me with this.
To your question a, I'm not sure but I don't think so. Nevertheless, the
question b is clear. You have to make owner to the user 'nobody'. If you don't,
ganglia can't write in that directory.
Thanks,
Mike
