Auto Discovery Results

Post by sleon »

Running on 64bit Cent OS Nagios XI.

I ran an auto discovery which yielded about 200 hosts. Then I clicked the results and it fails to load the page seems like the webpage goes unresponsive. I am thinking there's too much data its trying to process??

I am doing this in my lab as production has over 1500 devices so maybe there is a better way to do this?

Thanks!

I would segment your network scan to smaller sections, or subnet ranges, nagios is running a nmap scan of the network segment you define so breaking it up into slices often works to your advantage.

What is your recommendation for splitting this up? If I want to use this for my 1500 hosts is there an easier way I hope than small amounts?

By subnet. Try to only scan x.x.x.x/24 when possible.

Under the Scan Target selection in the Auto Discovery Wizard you can define a specific netmask. It is best to use /24 as abrist suggests.

Did that work for you, can we lock this up or did you want us to leave it open still? Either way is just fine.
