\\regards,

It's been a while since I've used nagios, but don't the permissions need to be nagios:apache? (or whatever user you are using for the web server)

Thanks for reply,

I'm new to nagios. I installed apache 2 + why some logs are available and some are not!! even though I'm using same permission nagios:nagios and I didn't change it since first day of installation.

Run the pre-flight check from the CL:

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

(correct the paths for your environment)

can you please elaborate more on changing path environment. I didn't get what do you mean.

Correct the PATH (/usr/local/nagios) if different. Clearly, since you posted the output, it's not.

I haven't put a lot of time into resolving your issue. One thing that I hearkened back on is that this sort of thing always used to happen to me after a fresh install. I always found that this doc resolved a large majority if my problems: http://assets.nagios.com/downloads/n...rom_Source.pdf

Follow it from beginning to end, unless you're using NagiosXI, and if that's the case, then you should be taking advantage of support.

Also, the forum over at Nagios-even the core forum for free-has always been *very* useful for resolving issues.

Given that neither of those files appear in the dir listing, I'm not surprised it complains.

if I undrestand what you are saying. Then I modify nagios.cfg and I remove (#) from this line cfg_dir=/usr/local/nagios/etc/hosts. after restarting nagios I get this Error: Could not open config directory '/usr/local/nagios/etc/hosts' for reading.
Error processing object config files!
therefore, I comment out cfg_dir=/usr/local/nagios to eliminate the error.

please explain how can let the files to appear in the dir listing

Are you using a hosts file? Does it exist? If not, then you cannot tell config that it should be checked.

If you have no hosts file, then what happened to it, btw? It's a standard cfg file.

I have hosts.cfg file (already configured to moniter some services), here are some lines from nagios.cfg

# OBJECT CONFIGURATION FILE(S)

# You can specify individual object config files as shown below:
cfg_file=/usr/local/nagios/etc/objects/commands.cfg
cfg_file=/usr/local/nagios/etc/objects/contacts.cfg
cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg
cfg_file=/usr/local/nagios/etc/objects/templates.cfg

# Definitions for monitoring the host
cfg_file=/usr/local/nagios/etc/objects/hosts.cfg

# You can also tell Nagios to process all config files (with a .cfg
# extension) in a particular directory by using the cfg_dir
# directive as shown below:

#cfg_dir=/usr/local/nagios/etc/servers
#cfg_dir=/usr/local/nagios/etc/printers
#cfg_dir=/usr/local/nagios/etc/switches
#cfg_dir=/usr/local/nagios/etc/routers
#cfg_dir=/usr/local/nagios/etc/hosts
