Autodiscovery

Hi There …

I recently properly installed librenms and deployed the snmpd agent on the estate of servers (both phisical and virtual) and switches we have

I added the private network we want to monitor and the discovery process started.As advised i manually added a few devices and these are the networks
$config[‘nets’][] = “10.72.0.0/16”;
$config[‘nets’][] = “10.190.74.0/24”;
$config[‘nets’][] = “10.190.75.0/24”;
$config[‘nets’][] = “10.190.76.0/24”;
$config[‘nets’][] = “10.190.77.0/24”;
$config[‘nets’][] = “10.190.78.0/24”;
$config[‘nets’][] = “10.190.79.0/24”;
$config[‘nets’][] = “10.190.80.0/24”;
$config[‘nets’][] = “10.190.81.0/24”;
$config[‘nets’][] = “10.190.82.0/24”;
$config[‘nets’][] = “172.30.0.0/16”;
$config[‘nets’][] = “172.31.0.0/16”;
$config[‘nets’][] = “10.200.0.0/16”;
$config[‘nets’][] = “10.201.0.0/16”;
$config[‘nets’][] = “10.202.0.0/16”;

can i configure so many networks lines in config.php ?
How discovery.php detect a new host ? (all the hosts are new for librenms)
Considering the librenms server is a dual cpu 8gb mem host how much time it will take to discover everything ?
Is there any log or config to achieve the discovery process logged verbosely to a level i can read a lines like “10.201.0.18 no response”
In around 4 hours it discovered around 40 hosts in which order it sweeps the networks ?

Can librenms correctly detect virtual host and phisical hosts ?

thanks

Francesco

Hi @Francesco_Ratto

All the details can be found in the documentation here :
https://docs.librenms.org/Extensions/Auto-Discovery/

Different protocols can be used by LibreNMS to discover devices (Routing Protocols, neighbours, arp table…)
You can disable some if you like.

In term of time, it depends how many devices you have, and how many hops are necessary to reach them. But it will eventually discover all the devices from the seeds you manually added.

I solved most of my issues with autodiscovery and got a little more proficiency on the tool

wonderful thing … and thank you for the support
