Error: Could not read host and service status information

Marc,
I did have to reinstall MySQL, but I did make sure all the dependencies
on Gentoo were dealt with, by recompiling (with emerge) Nagios, and used
a command that checks all .so dependencies on the system to make sure
nothing is broken. So I'm not so worried about MySQL.
So I think that since Groundwork monitor is using its own database to
store the configuration data I don't think that the original Nagios
database, that I setup isn't being used. So I'm not so sure about the
second question. Here is my config:

Those look reasonable. Was apache restarted _after_ it was added to the
nagios group? If so, I'd start looking at the mysql end of things. Is it
possible that the version of mysql libraries nagios was compiled against
is different than the mysql server itself? When you start nagios, can
you perform selects on the tables in the database using the same
authentication as nagios and see the data?
