I already run this one but here it is again ...

root@mpnagios:~# /usr/local/nagios/libexec/check_ping -H 172.16.1.251 -w 3000.0,80% -c 5000.0,100% -p 5
/bin/ping -n -U -w 30 -c 5 172.16.1.251

Lets re-compile your plugins:

Code: Select all

cd /tmp

wget https://www.nagios-plugins.org/download/nagios-plugins-1.5.tar.gz

tar zxvf nagios-plugins-1.5.tar.gz

cd nagios-plugins-1.5

./configure --with-nagios-user=nagios --with-nagios-group=nagios

make

make install 

service nagios restart

Now try re-scheduling a check through the web interface.

Should i use this new version of plugins or the same that i start with ?

[slansing]

Both versions should work, however if you are using an older version I would start with that for now.

Hi,

beforei re-compile the plugins (version 1.4.15 the same as i start) i comment ( or uncomment what was it ).... i put the "#" sign in front of ping syntax in cgi.cfg file ( #ping_syntax=/bin/ping -n -U -c 5 $HOSTADDRESS$) and then like you sad i execute the commands.

Code: Select all

cd /tmp

wget https://www.nagios-plugins.org/download/nagios-plugins-1.5.tar.gz

tar zxvf nagios-plugins-1.5.tar.gz

cd nagios-plugins-1.5

./configure --with-nagios-user=nagios --with-nagios-group=nagios

make

make install 

service nagios restart

I restart the nagios ( /etc/init.d/nagios restart ) and i try like you sad to re-scheduling through the web interface but i have this error.

Error: Could not open command file '/usr/local/nagios/var/rw/nagios.cmd' for update!
The permissions on the external command file and/or directory may be incorrect. Read the FAQs on how to setup proper permissions.

i guess i dont have put the right permissions there or ?

Also i notes that most of the commands in the web interface .... right of the host part not working

It seems you have more problems on your system then just a broken plugin can you run and show the following:

Code: Select all

ll -la /usr/local/nagios/var/rw/nagios.cmd

The location of the nagios command file may be different in your installation.

It seems you have more problems on your system then just a broken plugin can you run and show the following:

It is a brand new Ubuntu server 12.04.03 LTS and just installed Nagios noting more noting less.

I forgot to mention early that when i restart the nagios more hosts are back in normal, but some how, they turn to use the "/bin/ping" again.

Here it is the output of what you want

root@mpnagios:~# ll -la /usr/local/nagios/var/rw/nagios.cmd
prw-rw---- 1 nagios nagcmd 0 Oct 14 07:52 /usr/local/nagios/var/rw/nagios.cmd|
root@mpnagios:~#

At this point it looks like the issue is with the ping binary on your actual installation, there are a couple options, you can find the source for ping and re-compile it, then copy the binary over. Or you can provision a new system and re-install core on it. Right now this is beyond the realm and scope of Nagios Support so this will have to be taken care of separately.
