Hi !
I am using nagios to monitor my equipments .

I have to monitor the interfaces of my switches and routers, but is a big number of interfaces and equipments , i can't add it one by one manualy .

I searshed in internet , and i have found this script :

Code:

#!/usr/bin/perl
use strict;
 
open(MODEL, "modele.txt");
mkdir("modeles") if(!-d("modeles"));
while() {
  chomp();
  my($modele, $ip) = split(/;/);
  my @interfaces = `snmpwalk -c ecalyptus -v 2c $ip 1.3.6.1.2.1.2.2.1.2`;
  open(MODEL_CFG, ">modeles/switch-$modele.cfg");
  foreach(@interfaces) {
    if(/iso.3.6.1.2.1.2.2.1.2.(\d+) = STRING: "(.*Ethernet.*)"/) {
      my ($id, $interface) = ($1, $2);
      print MODEL_CFG "define service {
  hostgroup_name       $modele
  use                  generic-service
  service_description  $interface
  check_command        check_port_usage!$id!6000!8000
}
\n";
    }
  }
  close(MODEL_CFG);
}
close(MODEL);

i don't know how to use it , what should I write on modele.com file, and from where my script will get the $ip et $modele ?

Please help me .

Here i found this script :

If I had to guess, and I am, you should not use this.

Why not? Define a "big number of interfaces and equipments"
Are those host details stored in a file somewhere?
Where did you 'find' this script exactly?

Yes, you CAN add them manually. It's a matter of WANTING to add them manually.

So...you found the script, but instead of asking the author of the script for help, you posted it here, and want US to figure it out? Why don't you just email the person who wrote it, and ask? Their email address and other contact info is on their website. Also, there are six pages of networking plugins on the Nagios site...have you checked there?

You just say "monitor"...you don't say if you want a simple up/down, traffic information, or how detailed you want.

What do you mean "no way"??? You couldn't find out how, they haven't answered, or they told you no?? If you read the script, it's telling you the .txt file contains two things: the model of the Cisco router, and the IP address of the router, separated by comma.

Question about WHAT?? They didn't write that script...which plugin did you post about?? Each plugin has a different author and maintainer...but they are very easy to install/use and are typically well documented. Did you read/understand those docs?

Ok, so AGAIN, go to the Nagios plugin site, and pick the plugin that does exactly what you're looking for. Read the instructions and install it. Did you try to look this up?

for the moment, this satisfies your request.

Code:

nmap -PN IP -p port
telnet host port

such as

Code:

telnet towel.blinkenlights.nl 666

and process the output.

Put more than just a passing effort into it!
