Nagios-users Digest, Vol 58, Issue 22 - Remote Commands

 Hi Jamie. Following your advice, I ammended the service entry as
follows: 

define service{
        use                             remote-service         ; Name of
service template to use
        host_name                  		bamford-lon-fn1
        service_description             c: Disk Space
		check_command
check_remote_disk!-H 172.16.56.16!C:!95!99
		register
1
        }	

However, when I load the nagios web page, the status of this service now
comes up unknown. Have I still done this wrong or do I need to add -H
<serverip> to the generic-service which is defined in templates.cfg?

Hi, I think your only problem may that you have no "-H $HOSTADDRESS$" on
any of your defined commands - This means they will likely execute
locally, which is probably why you see the same output.

 

hope that helps

Hello. Hope you are well. First time emailing so thought better to put
too much info than not enough!

 

I'm trying to define services and commands that will monitor my remote
servers. So at present, I have my localhost for which I have the
following local commands in localhost.cfg: 

 

# Define local commands

# 'check_local_disk' command definition
define command{
        command_name    check_local_disk
        command_line    $USER1$/check_pdm2 --disk --drive $ARG1$
--warning $ARG2$ --critical $ARG3$
        }

# 'check_local_procs' command definition define command{
        command_name    check_local_procs
        command_line    $USER1$/check_winprocess --warning $ARG1$
--critical $ARG2$
        }

# 'check_local_load' command definition
define command{
        command_name    check_local_load
        command_line    $USER1$/check_pdm2 --processor --warning $ARG1$
--critical $ARG2$ --psamples $ARG3$ --pinterval $ARG4$
        }

# 'check_local_pyhsical_mem' command definition define command{
command_name check_local_physical_mem  command_line $USER1$/check_pdm2
--memory physical --warning $ARG1$ --critical $ARG2$  }

# 'check_local_virtual_mem' command definition define command{
command_name check_local_virtual_mem  command_line $USER1$/check_pdm2
--memory virtual --warning $ARG1$ --critical $ARG2$  }

# 'check_local_virtual_mem' command definition define command{
command_name check_local_pagefile_mem  command_line $USER1$/check_pdm2
--memory pagefile --warning $ARG1$ --critical $ARG2$  }  # Define a
service to check the disk space of system disk C on the local machine.  
# Warning if < 20% free, critical if < 10% free space.
define service{
        use                             local-service         ; Name of
service template to use
        host_name                       localhost
        service_description             System disk
  check_command     check_local_disk!C:!95!99
        }
# Define a service to check the number of currently running procs on the
local machine.
# Warning if > 250 processes, critical if > 400 users.

define service{
        use                             local-service         ; Name of
service template to use
        host_name                       localhost
        service_description             Total Processes
 check_command   check_local_procs!250!400
        }

# Define a service to check the load on the local machine. 5 samples
with 5 secs intervals.
# Warning at 80%, Critical at 95%
define service{
        use                             local-service         ; Name of
service template to use
        host_name                       localhost
        service_description             Current Load
  check_command   check_local_load!85!95!5!5
        }

# Define a service to check the physical memory usage the local machine.

# Critical if less than 90% of swap is in use, warning if 80% is in use

define service{
        use                             local-service         ; Name of
service template to use
        host_name                       localhost
        service_description             Physical memory
  check_command   check_local_physical_mem!80!90
        }

# Define a service to check the virtual memory usage the local machine. 
# Critical if less than 90% of swap is in use, warning if 80% is in use

define service{
        use                             local-service         ; Name of
service template to use
        host_name                       localhost
        service_description             Virtual memory
  check_command   check_local_virtual_mem!80!90
        }

# Define a service to check the page file usage the local machine. 
# Critical if less than 90% of swap is in use, warning if 80% is in use

define service{
        use                             local-service         ; Name of
service template to use
        host_name                       localhost
        service_description             Page file
  check_command   check_local_pagefile_mem!80!90
        }

 

So all these work fine for the localhost. What I'm trying to do now is
setup the exact same capability but for the remote servers, and this is
where I'm getting stuck. Although I can define a service for the remote
servers, the output displayed is the same as I have for my localhost. So
for example in the screenshot below, the c: Disk space service, the
remote service I tried to setup, is actually using the local command
line and showing the same output as the System Disk service on
localhost. 

 

 

 

Can you please advise on how to setup up equivalent remote commands
similar to the local commands above?

Eventually, I am looking to set up equivalent remote services for
current load, page file, phys mem etc that I currently have for
localhost. 

 

So far I have: 

 

C:\Program Files\ICW\etc\nagios\nagwin\hosts.cfg

define service{
        use                             remote-service         ; Name of
service template to use
        host_name                    bamford-lon-fn1
        service_description             c: Disk Space
  check_command     check_remote_disk!C:!95!99
        } 

C:\Program Files\ICW\etc\nagios\nagwin\localhost.cfg

# 'check_remote_disk' command definition define command{
        command_name    check_remote_disk
        command_line    $USER1$/check_pdm2 --disk --drive $ARG1$
--warning $ARG2$ --critical $ARG3$
        }

 

C:\Program Files\ICW\etc\nagios\nagwin\templates.cfg

# Remote service definition template- This is NOT a real service, just a
template!

 

define service{
  name       remote-service
  use                    generic-service
  max_check_attempts    4
  normal_check_interval   5
  retry_check_interval   1
  register      0
 }

 

 

I've seen something about this on the wiki at
http://wiki.nagios.org/index.php/Howtos:checkbyssh_RedHat but those
commands are more centered around red hat and ssh. 

Also tried http://wiki.nagios.org/index.php/Howtos:specific but windows
os isn't listed (unless windows uses same commands as those listed?). 

 

If you could help in any way I'd be most grateful. 

If I've missed something out/you need more info please let me know. Thx,
Paul.
