npc 2.0.0b

[blugger]

Hi!

I installed this plugin as described at http://trac2.assembla.com/npc

All but one thing looks fine.

When I click at "npc" -> "Process Information" I get a some check information.

The following two checks fail:

"Obsess Over Hosts"
"Obsess Over Services"

When I double click on "Obsess Over Hosts" for example, the browser asks me with a new window the following: "Start obsessing over hosts?"

When I click "Yes" the following message comes up in a new browser window: "Failed to open /usr/local/nagios/var/rw/"

======================================

I did everything as described in the nagios documentation:

/usr/sbin/useradd -m nagios
passwd nagios

/usr/sbin/groupadd nagios
/usr/sbin/usermod -G nagios nagios

/usr/sbin/groupadd nagcmd
/usr/sbin/usermod -G nagcmd nagios
/usr/sbin/usermod -G nagcmd wwwrun

./configure --with-command-group=nagcmd

make all

make install
make install-init
make install-config
make install-commandmode

make install-webconf

service apache2 restart

./configure --with-nagios-user=nagios --with-nagios-group=nagios
make
make install

chkconfig --add nagios
chkconfig nagios on

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg


===================



Starting nagios gives the following logging output:

I assume that I have the wrong rights set. Here are the rights:

==============

Since I did the commands mentioned above I get the following apache messages:

ok now the apache2 starts normal...

When I double click on "Obsess Over Hosts" for example, the browser asks me with a new window the following: "Start obsessing over hosts?"

When I click "Yes" the following message comes up in a new browser window: "/usr/local/nagios/var/rw must be readable and writable by the web server user"

What can I do now???
