Plugins

[MPIvan]

Hi all,

i would like to know how to download the specific plugin and run it. For example, here is the plugin and i would like to use it. Because this plugin is missing in my directory /usr/local/nagios/libexec or simple i dont have it. Or for example i would like to use check_snmp_load but when i try to download for example with wget i dont have nothing and what after the download, what have to do to get it work, what have to add in command.cfg and what in switche.cfg or what ever ...

Tnx in advanced !

In order to install a plugin such as the one you showed, you would simply wget the download URL into your /usr/local/nagios/libexec directory.
Most plugins offer a "-h" flag which will print a standard help listing explaining how to use the plugin, from here you can find the flags and required arguments the plugin needs to return check information. In the case of SNMP you will need to make sure you have the correct version number your device is running i.e "v1, v2" and it's community string interface, and port. It is recommended you first make sure you can return information from the Nagios server's shell before configuring the check into a host or service.

Hi,

i have some problems and i hope you all can gave me some explanation ... I have monitor some machines for hard drive capacity uptime and etc.. and for some machines the status and info is excellence, and for the others the status is "OK" but the status info is showing 0 for example: I have Server and for status gave me a warning and status info about the capacity is excellence "c: - total: 16.94 Gb - used: 15.05 Gb (89%) - free 1.89 Gb (11%)" ... also other machine it gave me an uptime status for that machine and its ok System Uptime - 20 day(s) 21 hour(s) 20 minute(s). Now i have other machine (connected with leased line, VPN) in other domain with domain users and i have installed NSClient ++ as administrator and for that machines i have status OK but the status info for example for Uptime is "System Uptime - 0 day(s) 0 hour(s) 0 minute(s) ". Also i have a router before that machines (off course ) and i monitor Uptime for that router and its fine. So the line is ok and i think is not a problem, the problem i think is domain or some other thinks. If you have any suggestions about it pleas shear wit us

You mentioned a few different checks. What is the exact issue that you are having? Can you show us the exact check that you are running in the command line, along with the output of it?

Here is an example

The second UpTime status showing that is 0 days 0 hours 0 minutes ... im using same plugin and im not change or modified just the name and ip of the host.

Here is something interesting.... So i have installed nagios and configure on Ubuntu server 12.04 LTS that runs on VMware Player. I make copy of that virtual pc (like backup) so i can test other stuff and now im running that machine and experiment on that (learning) . So i Power up the original one and put the same service for the same PC that i have problem ... and its work ok ... i have remember what i have change, and that is, in the cgi.cfg and in the nagios.cfg file i have change the time periods of refreshing and time period of checking the services and etc ... i have put back the defaults one back and now still cant get the right status information abut that two PC i have to get. I put new one on the (lets say the broken one)machine and it is OK it gave me the real status info abut UpTime service and etc ... all the PC are the same no different modification or something ... so what could be causing this problem on the again broken machine

Are you issues specifically with the uptime check? If so, could you post your service check and the remote host's nrpe.cfg file?

[MPIvan]

I dont have nrpe.cfg files on remote host's they are windows machines and im using the same version of NSClient++ same configuration and installation. I have change on some, not all, the community string/password. And no i have issues of other plugins like check_nt for checking the capacity of the hard drive.

I have change on some, not all, the community string/password

This sounds like SNMP based information, you supplied a screenshot regarding check_nrpe passed to your windows host. NRPE and SNMP are two different check types..

It appears as though you have given the wrong drive letter in the command definition for the check that was failing in the screen shot, can you show how you have the service defined?

[MPIvan]

Here it is from the windows.cfg

define service{
use generic-service
host_name PC005
service_description Uptime
check_command check_nt!UPTIME -s PC5nagios
}

define service{
use generic-service
host_name PC005
service_description C:\ Drive Space
check_command check_nt!USEDDISKSPACE!-l c -w 80 -c 90 -s PC5nagios
}

and in command.cfg

# 'check_nt' command definition
define command{
command_name check_nt
command_line $USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v $ARG1$ $ARG2$
}

and i have using NSClient++ on PC005 it is a big code but ill put it here the .ini file

Code: Select all

#   nscp settings --generate --add-defaults --load-all
