Good point. (a) I'd have lost history because the rrds were originally created with short names. I realize now it's a matter of renaming the host- specific RRA files in /var/lib/ganglia/rrds/. (b) The name resolution business was too finicky, and I was not alone in this, re: On Thu, 05 Jan 2006 03:16:30 -0800 Richard Grevis wrote in ganglia- general: > And of course, being a reverse DNS lookup, it will depend on > nsswitch.conf, which determines whether the data comes from /etc/ > hosts, NIS, or a DNS server. > And in our local environment, we have AD as well as bind DNS, and > even the case (upper/lower) of the fully qualified domain name can > depend on the phase of the moon. > Because of this, and because FQDN strings can be long, I have > patched my local ganglia PHPs to remove the domain component of the > hostname to avoid long strings as headings and on labels of graphs. (c) Looking over the php code, it seemed the changes needed would be more extensive, because one has to distinguish instances of $hostname used as array key and rrd file name from those used for display. Further, we have two web interfaces in use at our installation. I needed a solution quickly and went to the root. Personally, it was more fun to figure out and do :-) I wonder if Richard's php patches were for the generic interface - Richard, would they be open? Again, I don't know about circumstances for other sites, but my solution works well here. I decided I can drop the domain name entirely, because all hosts are in the same domain. A nicety could be to perhaps have a flag in gmond.conf.
