Nrpe 2.0

Nagios
1

Hello
I have nagios 1.2 and i have installed nrpe 2.0.my Os fedora 2.0.
when i installed nrpe2.0 on my server,i read the readme file.in that it is given that nrpe daemon and nrpe.cfg should be placed somewhere on remote host.Can nebody tell me who is experienced wth nrpe that where this somewhere to be installed…
heres wht is in readme file

Installing

The check_nrpe plugin should be placed on the Nagios host along
with your other plugins. In most cases, this will be in the
/usr/local/nagios/libexec directory.

The nrpe program and the configuration file (nrpe.cfg) should
be placed somewhere on the remote host. Note that you will also
have to install some plugins on the remote host if you want to
make much use of this addon.

I have copied check_nrpe to my /usr/local/nagios/libexec dir on server.

Thanks
Aparna

Check the “allow_host” parameter in your nrpe.cfg.
the value should be the ip adres of your nagios machine.

Another problem could be the port you

Hi
I have installed nrpe without ssl support

root@host [/bin]# ./check_nrpe -H HOSTADDRESS
CHECK_NRPE: Error receiving data from daemon.

10

And from my monitoring host i get the socket timeout err

11

Hope it will help you.

Install nrpe-2.0
cd /home/hashar/nrpe-2.0/
./configure && make .
The binary is /home/hashar/nrpe-2.0/src/nrpe , plugin is /home/hashar/nrpe-2.0/src/check_nrpe

Update the daemon for all hosts:

cp /home/hashar/nrpe-2.0/src/nrpe /home/wikipedia/nagios/bin/
Now from larousse update the check_nrpe plugin:

cp /home/hashar/nrpe-2.0/src/check_nrpe /usr/local/nagios/libexec/
Don’t forget to check the global configuration: /home/wikipedia/nagios/etc/nrpe.cfg .

Ashar launched the daemon on all apaches using:

dsh -f -N apaches
-e ‘/home/wikipedia/nagios/bin/nrpe -c /home/wikipedia/nagios/etc/nrpe.cfg -d’

if didn’t then tell me ur configuration…may be i will be of further assistance.

i am getting
LOAD

UNKNOWN 05-05-2005 03:27:30 1d 1h 9m 46s 3/3 Incorrect command line arguments supplied

wht do i need to do so tht i can monitor load and diskspace on remote host

Thanks

15

From the error you get, it looks like you have “Incorrect command line arguments supplied” so double check your syntax.

16

Hello when i run this command from shell u get the following error

./check_nrpe -H HOSTADDRESS -p 5666 -c check_load

CHECK_NRPE: Socket timeout after 10 seconds.

What can be done for this
Thanks

17

./check_nrpe -H HOSTADDRESS -p 5666 -c check_load

Check the syntax again for the check_nrpe command. I seriously doubt that -H HOSTADDRESS is valid. Looks to me, like it should be some ip address, but I could be wrong.

18

ya you are right .sorry my mistake by hostaddress i meant ipaddress.
i entered ipaddress only but i get the above err…
Thanks

According to the README file, there are many items that you might have NOT done. I’d suggest to read the README file that came with nrpe, and make sure that you have completed each and every step. Did you restart xinetd, is just one example of a step you might have missed.

Hi
xinetd is to be restarted if i am not running nrpe as deamon on remote host is it right?
So i didnt do nethng wth xinetd coz i am running nrpe as deamon.
wht can be done

Thanks for helping me
