This has come up a few times in the past I believe, once a few years ago when we had similar problems on some Solaris servers we were monitoring with a similar /etc/hosts file setup.
I believe that ganglia just uses system calls like gethostbyaddr which rely on the OS/system libs to determine how to resolve names (for glibc see /etc/nsswitch.conf). To get consistent results you would probably have to force ganglia to always do DNS lookups (like changing it to use bind libs instead), but I think this might introduce some portability problems (or some people might not want to rely on DNS so this would have to be made a config option). We just ended up changing the format in our /etc/hosts files instead of opening up this can of worms. ~Jason On Tue, 2005-08-16 at 16:56 -0500, [EMAIL PROTECTED] wrote: > Steven, > Thanks for the response.
