Thanks Matthias: Now it is accumulating, and I get graph
displays from the WEB page.

Hi Hiram !
Before trying multicast I would try to use unicast
in gmond.conf. It's possible that your network
environment (e.g. switch) does not handle IP multicasting
properly.
For unicast the logic has to be that your gmond sends itself
data. For instance:
gmond.conf:
....
udp_send_channel {
host = mitzie
port = 8649
}
/* You can specify as many udp_recv_channels as you like as well. */
udp_recv_channel {
port = 8649
}
Then issue a
telnet mitzie 8649
You should get a reply with lots of XML tags.
Once you get the unicast going, then move to IP multicasting if
necessary.
Hope that helps,
Matthias

Thanks Seth and Ben for the advice. I can run both gmond and
gmetad in debug mode. gmond says it is collecting data and
sending messages (who is it sending them to ?)
gmetad starts up and says:
[EMAIL PROTECTED] rrds]# pwd
/var/lib/ganglia/rrds
[EMAIL PROTECTED] rrds]# ls -la
total 16
drwxr-xr-x 2 root root 4096 Jun 19 2006 .
drwxr-xr-x 3 root root 4096 Feb 17 21:26 ..
[EMAIL PROTECTED] rrds]# gmetad -d99
Going to run as user root
Sources are ...
Source: [mitzie, step 10] has 1 sources
127.0.0.1
xml listening on port 8651
interactive xml listening on port 8652
cleanup thread has been started
Data thread -1271288912 is monitoring [mitzie] data source
127.0.0.1
[mitzie] is a 2.5 or later data stream
hash_create size = 1024
hash->size is 1031
hash_create size = 50
hash->size is 53
And then, for every [interval] seconds it merely says:
[mitzie] is a 2.5 or later data stream
[mitzie] is a 2.5 or later data stream
What's up with the "Data thread -1271288912" ? That seems a bit
weird.
It never says anything about polling anything, or writing
any files. Nothing, just all about this data stream version.
I've tried it as user setuid "ganglia" and user "root"
Same behavior either way. (with appropriate owner on ganglia/rrds/)
My full gmetad.conf spec says:
data_source "mitzie" 10 127.0.0.1:8649
gridname "HomeGrid"
authority "http://localhost/ganglia/";
trusted_hosts 192.168.1.71 127.0.0.1
all_trusted on
setuid off
Anything wrong with that ?

the directory sits there empty. gmond and gmetad are running
just fine.
I'm sure you've already checked this, but just in case, I have to
ask -
what are the permissions on /var/lib/ganglia/rrds/? Does the user as
which gmetad is running have write privs on that directory?
