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. -James
