If Nagios is indeed not running, this is a normal error message. It simply indicates that the CGIs could not obtain the current status of hosts and services that are being monitored. If you've just installed things, make sure you read the documentation on starting Nagios. Some other things you should check in order to resolve this error include: 1. Check the Nagios log file for messages relating to startup or status data errors. 2. Always verify configuration options using the *-v* command-line option before starting or restarting Nagios! 3. Make sure you've compiled the main program and the CGIs to use the same status data storage options (i.e. text file or database). If the main program is storing status data in a text file and the CGIs are trying to read status data from a database, you'll have problems. *If i do run the following command # ./nagios -v multinag.cfg i get the following, * root@rndpgt02 # ./nagios -v /opt/csw/nagios/etc/nagios.cfg Nagios 2.3.1 Copyright (c) 1999-2006 Ethan Galstad (<a class="moz-txt-link-freetext" href="http://www.nagios.org">http://www.nagios.org</a>) Last Modified: 05-15-2006 License: GPL Reading configuration data...
