Hardian,
For displaying localhost u need to run gmond agent on localhost machine and
also add it to trusted hosts in gmetad.conf file.
One of the ways to remove old names is to restart all gmond and gmetad
processes, where the old hosts are flushed by ganglia.
Alternatively you can set a timer in gmond.conf file.
If you add the line
globals {
host_dmax = 3600
}
then hosts will be removed from host tables when they haven't been heard
from in 3600 seconds.

Subject: Re: [Ganglia-general] Graphs couldn't show up and I have followed the
README file...
Hi Chang,
Thank you for your reply, I really appreciate it. Last night, I reinstalled
again and it worked. The graphs are showing up now. Apparently, I made a
mistake and it took 4 days to realise it. Silly me :p.
The problem was, after I installed rrdtool and then I installed
ganglia-monitor-core3-0-1.tar.gz.. But then, I installed again
ganglia-gmond-3.0.1.rpm and ganglia-gmetad-3.0.1.rpm and
ganglia-web-frontend-3.0.1.rpm. While actually, I don't have to do that. All I
need to do, just copy the gmond, gmetad and weeb directory which came along
with ganglia-monitor-core3.0.1.tar.gz. Because in ganglia monitor core, I have
set the path of rrdtool.
The graph thing is done, now. But I have one more problem though. Some of the
nodes were listed with the old names while I have changed it to a new hostname.
Do you know how ganglia could pick up the old hostname? And all nodes are
visible but the localhost isn't visible. Do you know how to get the localhost
visible?
Thank you very much for your time.
With kind regards,
Hardian

You need a RRDTool-enabled version of PHP that can create graphics on
the fly. Forget what it's called, but on debian at least, it's a
seperate package from the normal PHP. Also, I'm not sure if it's
necessary, but I installed the XPM-supporting version of RRDTool (as
one is distributed on my OS without it).

The graphs are URLs to PHP scripts - why not look at the URLs of one
of them and see if you get a graph. If not, you'll probably get a
helpful PHP error message.

Make sure your RRDTool is compatable with your PHP install. That's my
guess.
Sorry in advance if it's not helpful.
