Hi Antonio,
I could finally see the Ganglia up running in the webinterface. I restarted
everything and now its fine.
Thanks a lot for your help.
Now I am looking for monitoring hadoop using Ganglia. I added the metrics
properties to the hadoop-metrics properties. Is there something else I have to
do to see the hadoop metrics in ganglia?
Thanks,
Mike

Yes, I have the web folder copied to /var/www/ganglia
Do we have to keep in gmond.conf,
tcp_accept_channel {
port = 8649
}
Because trying to start gmond with this included in the conf gave me an error
"Unable to create tcp_accept_channel". So I removed this from gmond.conf
Thanks,
Mike

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
Going to run as user nobody
Sources are ...

...etc
D) Here are the relevant parts in my /etc/ganglia/gmond.conf
cluster {

owner = "myclusterowner"
latlong = "unspecified"
url = "unspecified"
}
host {
location = "IP_of_EC2"
}
udp_send_channel {
mcast_join = IP_of_EC2
port = 8666
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,
Mike
If I'm not wrong, this error is showed when gmond is already running. You have
to keep this lines to get working the system. Try readd the lines, stopping
gmond and restarting, it must work fine.
One question: you can see the ganglia website in any case, isn't?
Regards,
Antonio.
