upgrade to 4.0.8, cgis not working

Posted: Fri May 08, 2015 2:03 pm

I'm getting the common error
Whoops!

Error: Could not read host and service status information!
after upgrade from 3.5.1 to 4.0.8

The config test runs clean. The service starts up, and I see it logging some soft warnings on a few hosts, which is usual.

I'm not seeing errors in the apache log about permissions. Googling and checking things others have run into has not produced
a good lead into resolving the error.

Here is the tail of my nagios.log:

Was this a source upgrade or did you use some package manager?

What is the platform/OS?

A good place to start troubleshooting might be the apache error_log. Can we see the tail of it?

Along with jdalrymple's response, please post your /usr/local/nagios/etc/nagios.cfg and the output of the following command:

Code: Select all

ls -l /usr/local/nagios/var

BTW, the nagios.log which I have configured is in:
/var/spool/nagios/nagios.log

The nagios log under /usr/local/nagios/var

is an oddity, and only contains these two lines with every start up:

Code: Select all

[1431088940] Error: Cannot open main configuration file '/' for reading!
[1431088940] Error: Failed to process config file '/'. Aborting
Yet, I see a stream of seemingly meaningful logging as I posted before in the /var/spool/nagios location
and the verify with -v shows it is aware of the configuration file definitions.

Your nagios.cfg doesn't contain a path to your status_file
At a very minimum I would add

Code: Select all

state_retention_file=/usr/local/nagios/var/retention.dat
status_file=/usr/local/nagios/var/status.dat
Then restart nagios

Thank you Scott. That was perfect. I am back in business with a good
Nagios Core web site again. The Home page shows the daemon is running,
and now pages such as tactical overview, hosts, services, all work again
with no "whoops" error. You guys rock!
