Unfortunately, I do not have that script on my Nagios server instance. I tried to connect using the usernames and passwords defined in the file /usr/local/nagiosxi/html/config.inc.php . I successfully checked all three sets ( $cfg['db_info'] for nagiosxi , ndoutils , and nagiosql ). I'm not sure if ...

Hello, we are getting closer :-) I executed these commands (redacted): # su - nagios $ /usr/local/nagios/libexec/check_db2_health ... OK - 0.09 seconds to connect as USER | connection_time=0.0851;2;5 $ locale LANG=en_US.UTF-8 LC_CTYPE="en_US.UTF-8" LC_NUMERIC="en_US.UTF-8" LC_TIM...
