localhost and switch status Down

[csandy1703]

Deal All

I have installed NagiOS 4.0.0. with no errors.

However after opening nagios interface, localhost status is DOWN always.

Also I added one switch in /usr/local/nagios/etc/objects/switch.cfg, but it also showing DOWN.

Pl help

I'm also having this same problem...I've found threads elsewhere outside the official support forum that suggest the service.cfg and hosts.cfg should be checked for syntax errors, etc, however after a clean install on my part, I don't find those files anywhere...

In a clean install, localhost.cfg should hold these config objects. What is the listing of the directory:

Code: Select all

ls -la /usr/local/nagios/etc
ls -la /usr/local/nagios/etc/objects

[volpeadmin]

Well, you have a localhost.cfg, and it is not empty. Is the objects folder included in the nagios cfg?

Code: Select all

grep cfg_ /usr/local/nagios/etc/nagios.cfg

[volpeadmin]

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
cfg_file=/usr/local/nagios/etc/objects/localhost.cfg
#cfg_file=/usr/local/nagios/etc/objects/windows.cfg
#cfg_file=/usr/local/nagios/etc/objects/switch.cfg
#cfg_file=/usr/local/nagios/etc/objects/printer.cfg
# extension) in a particular directory by using the cfg_dir
#cfg_dir=/usr/local/nagios/etc/servers

#cfg_dir=/usr/local/nagios/etc/routers
# object configuration files (see the cfg_file and cfg_dir options above).

By default the host checks are just check_ping. Have you verified that your host is allowing responses from icmp packets and allowing them output or that your switch is responding to them?

[volpeadmin]

# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- anywhere anywhere tcp dpt:http
ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED
ACCEPT icmp -- anywhere anywhere
ACCEPT all -- anywhere anywhere
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ssh
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:5903
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:5902
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:5901
ACCEPT icmp -- anywhere anywhere

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

[sreinhardt]

well, everything looks good there. Let's do a ping to both and just be 100% sure that icmp is working.
