How do you montor an entire subnet

[topperh]

Hi,

I have several /19 subnets that I need to monitor but I am unsure how I can enter the entire subnet in cacti.

All I need to ping statistics.

Any help would be appreciated.

You don't enter a subnet, you add each device you want to monitor separately.

There must be another way.

What I am looking to do is to enter 10-11 /24 subnets and all I want to do is monitor packetloss and latency. No SNMP is required.

I really do not want to sit and 2500 nodes individually if it can be done by entering the entire subnet one at a time.

Combine the discovery plugin with autom8. The only problem you are going to run into is that discovery requires SNMP on the device to be enabled to match the sysdesc to a discovery template so it will add it.

The only other real option is to use the command line scripts and write a script to add the hosts and graphs.

the cli scripts are the only way to do it fast , to get you started:

http://www.cacti.net/downloads/docs/html/scripts.html

it's easy after you do some tests and see it in action.

i added 500 devices and 4000 graphs like this just for fun.

ps: if you use the shell script from slaptijack you can generate the ip list by using excel and select a few ip's and drag down.

Hope it helps.
