Change your host definition to look exactly like the following:

define host{
use generic-host ; Inherit default values from a Windows server
host_name generic service
alias Windows Server
address 192.168.142.125
}

You have defined your other hosts in your second post with generic-host and the first host definition with windows-server. That is where you are getting the error from nagios, change that and you should be alright!!!


#4

thanks buddy i have done the following changes in my windows.cfg file.after that also i am getting error like this

Error: Invalid max_check_attempts value for host 'generic service’
Error: Could not register host (config file ‘/usr/local/nagios/etc/windows.cfg’, starting on line 2)

edited windows.cfg file

define host{
use generic-host ; Inherit default values from a Windows server
host_name generic service
alias Windows Server
address 192.168.142.125
}

define service{
use generic-service
host_name dev-sudhesh
service_description NSClient++ Version
check_command check_nt!CLIENTVERSION
}

define service{
use generic-service
host_name dev-sudhesh
service_description Uptime
check_command check_nt!UPTIME
}


#5

Add the following into your host definitions:

You can also change that to any other value such as 3 or to what ever you want. That should fix the problem. Here is a couple of good websites that I use as a reference when I get stuck:

  1. nagios.sourceforge.net/docs/2_0/xodtemplate.html
  2. totkat.org/pages/nconf_commands.shtml

Let me know if you have any more questions.


#6

thanks geofoxer that doucment was very useful for me.
right now i am getting error like this
Checking services…
Error: Service check command ‘check_nt’ specified in service ‘CPU Load’ for host ‘dev-sudhesh’ not defined anywhere!
Error: Service check command ‘check_nt’ specified in service ‘Explorer’ for host ‘dev-sudhesh’ not defined anywhere!
Error: Service check command ‘check_nt’ specified in service ‘Memory Usage’ for host ‘dev-sudhesh’ not defined anywhere!

Error: Service check command ‘check_nt’ specified in service ‘W3SVC’ for host ‘dev-sudhesh’ not defined anywhere!
Error: Service check command ‘check_nt’ specified in service ‘c:\ Drive Space’ for host ‘dev-sudhesh’ not defined anywhere!

and can i know wht is the function of checkcommand.cfg and command.cfg…


#7

does check_nt exist in /usr/local/nagios/libexec?
if not, did you download the nagios plugins? If you haven’t, do that.

command.cfg has all of the command definitions, so when you use, say, check-host-alive, it finds the command in command.cfg.


#8

yes check_nt exist in /usr/local/nagios/libexec


#9

thanks a lot i am able to monitor my linux machines.but i am nt able to monitor my windows machines.by default i can monitor ping but other service i am not able to monitor and in the nagios web interface i am getting a error like check_nt: Could not parse arguments.

SAMPLE HOST CHECK COMMANDS

################################################################################

This command checks to see if a host is “alive” by pinging it

The check must result in a 100% packet loss or 5 second (5000ms) round trip

average time to produce a critical error.

Note: Only one ICMP echo packet is sent (determined by the ‘-p 1’ argument)

################################################################################

SAMPLE NOTIFICATION COMMANDS

These are some example notification commands. They may or may not work on

your system without modification. As an example, some systems will require

you to use “/usr/bin/mailx” instead of “/usr/bin/mail” in the commands below.
