Device Monitor - a tool for automatic network device monitoring and detection

[mooh]

Not every plugin is for everyone — install what fits your needs. 🙂

I didn't mean to belittle your effort. In fact, I appreciate every effort to improve OPNsense.

I just not sure what the size of the target audience for all this host discovery stuff is, yours and the new component of OPNsense. If I want to know what's going on on my network, I ask it directly via SNMP or an all-in-one solution like Unifi or Omada. Only small, unmanaged networks don't already provide that functionality. How many are there using OPNsense?

I have an older version of Device Monitor installed and working.  It is great !!!

I am happy with it, but is there a way to update to this new version, or do I need to fully uninstall/reinstall?

Thank you.

Hi Steffen,
The hostname field works as follows: the plugin pulls the hostname from Services → ISC DHCPv4 / DHCPv6 → DHCP Static Mappings — specifically the Hostname field for each entry. If a device doesn't have a static mapping with a hostname defined there, the field will simply remain empty, as the plugin has no other automatic source for this information.
You can also fill in the hostname manually directly in the plugin, but note that this is stored only in the plugin's own database — it does not propagate back to OPNsense DHCP or any other system.
So the short answer: populate the Hostname field in your DHCP static mappings and it will appear automatically.

I have hostnames defined at Dnsmasq because I think ISC is deprecated. So it would be nice to support Dnsmasq too.

Figured it out.  Deleted the existing /tmp/opnsense-devicemonitor folder.  Then downloaded, unzipped, and copied over the new files.  Then just re-ran sh install.sh.

Now up-to-date. ☑️

Good day, exactly as you asked. If you use sh install.sh, everything except the database will be deleted before installation. After installation, the plugin will be started again. If you use sh uninstall.sh, everything will be removed.

Good day, I just converted my home network from ISC to DNSmasq and it will take a while before I get to it and modify the plugin. but don't worry, it will happen :).

Hello, I recently switched from pfSense to OpnSense and this option was standard in the system and I use it to check if an uninvited guest is connecting. Or when I connect a device, I find out its IP address. I don't have unifi, or rather I only use AP AC RL and I have a classic L2, L3 switch. So OpnSense will provide me with the necessary information :). I originally wrote the plugin just for myself, but I decided to share it with others... I would like the plugin to be offered as a standard package, but that's too much for me for now :).
