Nagios Support Forum

hi I recently update Nagios Core 3 and now I'm on version 4.0.4 but I lost all my hosts ?

how do I reenter them into the new version ?

I'm new at this and using nconf

please help !

I can't really speak for Nconf since it's not our product, but the configs should still be there depending on how you updated. Can you provide more details as to the process you followed?

Im not sure but if I'm not mistaken I didn't do a upgrade I installed it instead of upgrading :S mistake

I've not used nconf but from looking at the documentation:

http://www.nconf.org/dokuwiki/doku.php? ... tart_guide

You need to update nagios.cfg to point to the location that nconf dumps config files.

Further questions should be posted in their forums:

http://forum.nconf.org/

there is no reason why nconf cannot continue to work, the issue is most likely like box293 has said your configuration before was not in a standard location
I (unlike everyone else apparently) use nconf I love it

I opted on my installation to use a really standard configuration structure for nagios /usr/local/nagios/etc/... if you are not using that structure for your config you might want to consider moving your config there for consistency.

ok I had to change de Nagios.cfg but now I'm getting this error

Whoops!

Error: Could not read host and service status information!

The most common cause of this error message (especially for new users), is the fact that Nagios is not actually running. If Nagios is indeed not running, this is a normal error message. It simply indicates that the CGIs could not obtain the current status of hosts and services that are being monitored. If you've just installed things, make sure you read the documentation on starting Nagios.

Some other things you should check in order to resolve this error include:


1.Check the Nagios log file for messages relating to startup or status data errors.
2.Always verify configuration options using the -v command-line option before starting or restarting Nagios!


Make sure you read the documentation on installing, configuring and running Nagios thoroughly before continuing. If all else fails, try sending a message to one of the mailing lists. More information can be found at http://www.nagios.org.

can someone please help me... ??????????

What OS are you using to install Nagios and nconf?
Can you login to your system as root, run the following and post back the output? Can you post your nagios.cfg file so we can view it?

were you using mklivestatus before your upgrade?

Let us know when you get a chance to answer the above questions @phil.lay151.
