You'll need to:

• Put the plugin in the /usr/local/nagios/libexec/ directory
  create a command
  create a service that users the command

Have a read of this:

http://nagios.sourceforge.net/docs/3_0/ ... bject.html

Followed by this:

hi !

can someone help me to finish this

1. firstly I created script file, using copy and paste script in below URL to notepad and create it as check-cisco.pl

https://github.com/ranl/monitor-utils/b ... k-cisco.pl

2. then I moved check-cisco.pl file to /usr/local/nagios/libexec/ directory

3. created command in command.cfg file

# 'check-cisco' command definition
define command{
command_name check-cisco
command_line /usr/local/nagios/libexec/check-cisco.pl -H $HOSTADDRESS$
}

4. finally created service in switch.cfg file

define service{
use generic-service ; Inherit values from a template
hostgroup_name switches
service_description cisco switch
check_command check-cisco!/usr/local/nagios/libexec/check-cisco.pl
}

but its not working.. can someone show me what is wrong and correct !!

Thanks

You are getting there.

The first thing to test is to make sure the script is correctly running at the command line.

Code: Select all

su nagios
/usr/local/nagios/libexec/check-cisco.pl -H the_cisco_device_ip_address

What output does this produce?
I suspect you are going to need to add some more options to the command such as -C public -t temp
Once you have the command working and returning correct output, then you will know how to define the command and service.

Your command definition will need to allow arguments:

Code: Select all

command_line /usr/local/nagios/libexec/check-cisco.pl -H $HOSTADDRESS$ $ARG1$

The $ARG1$ allows you to pass through arguments to your service like "-C public -t temp"

To pass arguments to the command, change your service definition to:

Code: Select all

check_command check-cisco!-C public -t temp

Anything after ! is $ARG1$.

when I running the script at the command line its showing this,

[root@localhost ~]# /usr/local/nagios/libexec/check-cisco.pl -H 10.238.80.11

Your problem is a Perl problem, not specific to Nagios at this point. You need to get the Net::SNMP Perl modules installed on your machine. Most likely, you can do it via CPAN as root:

Code: Select all

perl -MCPAN -e shell
install Net::SNMP

If that fails for some reason, you can head to http://search.cpan.org/~dtown/Net-SNMP-v6.0.1/ and download, compile, and install from source.

[l_freez]

can you tell me how to install it. I tried to install it using this command but it not work

[root@localhost ~]# perl -MCPAN -e 'install Net::SNMP'
Can't locate CPAN.pm in @INC (@INC contains: /usr/local/lib/perl5 /usr/local/share/perl5 /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5 /usr/share/perl5 .).
BEGIN failed--compilation aborted.

and also tried this its showing

[root@localhost tmp]# yum install Net::SNMP
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
* base: centos.excellmedia.net
* epel: ftp.riken.jp
* extras: centos.excellmedia.net
* updates: centoss5.centos.org
Setting up Install Process

Error: Nothing to do

[l_freez]

after so many tried I installed it. below commands are which I tried

#perl -MCPAN -e shell
#install Net::SNMP
#yum install Net::SNMP
#perl -MCPAN -e 'install Net::SNMP'
#perl -MCPAN -e 'install Net::SNMP'
#yum install Net::SNMP
#yum install cpan App::cpanminus

#perl -MCPAN -e 'install Net::SNMP'

#perl -MCPAN -e shell
#install Net::SNMP

I assumed above things are installed well and now its showing this

[root@localhost ~]# /usr/local/nagios/libexec/check-cisco.pl -H 10.238.80.11
Syntax Error !
