True, but one hopes that DNS is fairly stable, and if you have DNS issues, Ganglia is probably not high on the list of things to fix. ;-) However, if you are dealing with machines that use DHCP, or do not have stable addresses, then using a UUID would indeed be useful in this case. > 2) Host changed name/ip even though it is the same physical server, > the only way to restore/keep historical data is by manually renaming > the filename -- with UUID, this is not necessary Well, by renaming a single directory per host. That's not really a whole lot of extra effort. :-) -- Jesse Becker GPG Fingerprint -- BD00 7AA4 4483 AFCC 82D0 2720 0083 0931 9A2B 06A2 ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Ganglia-general mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/ganglia-general
