Thank you very much for the assistance, but I just realized that I
accidently missed a, apparently, crucial step in the installation.
I forgot to add the second part of the broker_module command:
broker_module=/usr/local/nagios/bin/ndomod-2x.o
config_file=/usr/local/nagios/etc/ndomod.cfg
Adding it cleared up my database issues and chmod 777 /tmp cleared up my
second issue. Anyway I appreciate your quick response to my question.

Subject: [Nagios-users] NDO and Nagvis Integration
Hello,
I am having an issue integrating NDO and Nagvis into my Nagios
installation.
I get the following error when I try to view a nagvis map:
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL
result resource in
/usr/local/nagios/share/nagvis/nagvis/includes/classes/GlobalBackend-ndo
my.php on line 58
nagiosNotRunning: NDOMy: Nagios not running (Backend ndomy_1)
NDO reports that Nagios is not running
After reading this board and the nagvis website apparently this is not
an unusual error; however, I have taken all the steps that have been
suggested previously and still nothing. Here is a list of all the
pertinent information I can think of.
System:
CentOS 4.6
MySQL 4.1.20
Nagios 2.9
Nagvis 1.2.2
NDOutils 1.4b7
Troubleshooting sofar:
Ensured nagios.cfg file has
Event_broker_options=-1
Check_external_commands=1
Command_check_interval=10s
Checked ndo2db.cfg and ndomod.cfg for appropriate database settings
Monitoring of /var/log/messages revealed no information in reference to
'ndo' (ie. Cat '/var/log/messages | grep ndo').
I am also getting an error on the same page that says:
Warning: Unknown: open(/tmp/sess_7ebd84ff779d34acebacc2ad3ad9416a,
O_RDWR) failed: Permission denied (13) in Unknown on line 0
Warning: Unknown: Failed to write session data (files). Please verify
that the current setting of session.save_path is correct () in Unknown
on line 0
I am not sure what exactly this is saying because it does not reference
a file that I can see, but I have double checked the directory and file
permissions in /usr/local/nagios/share/nagvis and everything seems to be
set appropriately.
I would appreciate any available assistance with this matter, and I look
forward to getting nagvis up and running.
