SLES 11 Nagios - Error: Could not read object configuration!


#1

I’ve installed Nagios version 3.0.6 via Yasts, installation is successful but when I tried to browsed to the sub menu under **http://nagios-server/nagios **I keep getting the error below (in red).

Whoops!

Error: Could not read object configuration data!

Here are some things you should check in order to resolve this error:

Verify configuration options using the -v command-line option to check for errors.
Check the Nagios log file for messages relating to startup or status data errors. 

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 nagios.org.

I’ve also verify the configuration using -v command-line option, as shown below no error is found.

I suspect that it is some file permission issue but I’m not sure what went wrong, did a ‘locate nagios’ which shows the location of all nagios files and directories

I’m sure it’s not what you want to hear… but simply purge the installation via YAST and install from sources. This ensures the file are in a known position and it makes it way easier to help.
