I see, but I also see the same effect in the nagios Availability report. This only shows the availability since the change in host_name... (admittedly, I'm running 3.0.5 and perhaps this is different in icinga, I'm trying to learn icinga by way of our old nagios ;-)) > when initially defining a host->service relation, this should chosen > wisely and unique. changes to those are not expected and not the normal > case - so the manual procedure of moving the stored rrd and xml files of > pnp4nagios need to be done manually. if you require some sort of > automated detection of changed host/service names, you need to make sure > that a. something diffs old vs new config (core doesn't do that) and b. > pnp4nagios gets aware of thesechanges (doesn't get that now, just plain > new information). This wasn't very clear to me from the documentation (that everything is identified by the host_name). It would be nice if there was a script that could rename hosts without losing the history, but I guess it entails a lot of modifications (potentially, even altering the archive logs is required?). But it's better to setup the configuration with well chosen host_name variables ;-) Cheers /Simon ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
