Some times ago i was experiencing a problem with nagios3 in Debian.
After installing nagios, browsing the nagios web page, i got the following error:
Could not read object configuration data!
Nagios log messages didn’t reported any useful information. So googling around and making some test i discovered that was a permission problem of the nagios cache files. So i solved my problem changing the group of the /var/cache/nagios3/ directory as follow:
chgrp -R apache /var/cache/nagios3/
Previously was set to www-data .
Enjoy!
Thanks, this got me going…appreciate you sharing this.
