First, I'd like to say that I am very impressed with Ganglia now that
it's up and running on my boxes. I have built 2 separate RPMs for ia64
(one for SUSE and one for RHEL 3) that I'd like to contribute if the
need is great enough. However, that's not why I'm posting.
I have gone through the archives and have some questions about things I
am seeing on the graphs. First, currently I have 3 systems (2 SGI Altix
boxes and a front end gmetad server that is only for the web interface)
being monitored, but the hostname has me confused. On 2 of the servers
(one SGi box and the web front end) I get the FQDN of the server. But
on the other SGI box I get only the actual hostname, not the FQDN. The
hostnames are all set for the FQDN, and I noted in the archives some
items related to reverse lookups, but none of that is a problem that I
can see. In gmetd.conf I have:
data_source "Newton" newton.hpcc.ercbroadband.org
data_source "Winterstar" winterstar.hpcc.ercbroadband.org
With Newton being the one that shows up as 'Newton', and Winterstar
showing up as winterstar.hpcc.ercbroadband.org in the Web GUI. I do not
understand why this is, any ideas?
Now, second question, I want to 'pretty up' the Interface to include
some company info. I've tried to get the cluster name setup by using
the same cluster name in gmond.conf for all boxes, but only the web
interface shows up in it. I also wanted to change the 'grid' name, but
I get wonky CPU totals when I change it on the web server. I know this
is something simple, but I'm not totally knowledgeable of the
architecture of ganglia to know what it is. The docs are kind of vague
on this and the list archives didn't really give me much either. Can
someone help me?
