tarjei- when gmond gets a packet from a host it pulls the source address from the header and checks if the ip/hostname pair is in its internal cache. if the ip is in the cache .. it uses that name... otherwise.. gmond will do a gethostbyaddr() to resolve the name. if gethostbyaddr() fails.. it puts the ip address as the name.
take a look at the data source which is giving you problems. log onto the machine and pull the XML from port 8649 (telnet localhost 8649). take a look at the IP addresses and try to resolve them with nslookups from the data source machine. if that machine cannot resolve the names then you've found your problem. let us know otherwise. -- matt Today, Tarjei Knapstad wrote forth saying... > On Thu, 2002-11-14 at 18:47, [EMAIL PROTECTED] wrote: > > > > I was having a similar problem in my test environment with machine that did > > not have DNS entries.
