Hello!
I have been struggling with a problem for some time, the network inventory. It's almost done, but the SNMP query is weird. Maybe I missed something, but after reading a lot of descriptions and forums, I couldn't get any further.
I have defined a network discovery with 4 ip ranges and a linux (debian12) agent is doing the work. Apparently (according to the logs) it does the job, but the snmp query only returned results for 3 unifi devices. and there are quite a few network switches in the system that we monitor via SNMP. So SNMP works on them, snmpwalk run on the agent returns all relevant information, but z snmp inventory returns nothing. I am now pasting the logs and snmpwalk details of one device here, but the situation is similar for the others. It did not recognize the printers either, even though the counters are also queried via snmp.
The data:
GLPI: GLPI 10.0.16
GLPI Agent: 1.10 Linux via eg script --type=all
OS: Debian 12
INventory: GLPI Inventory from marketplace
The switch log from agent:

What that found looks like this: this is a "full match" result in the database. How can I update the database? or how can I get him to learn about network devices and printers? The TP-Link is a partial match

Hello!
I read everything I could, manuals, forums, I even searched the source on github, but I couldn't find the solution
I find the device with network discovery, netinventory scan the device (ip range mode), and nothing. The logos are up.
I manually assign it to network devices. I set the SNMP credentials before that, I tested the SNMP result with snmpwalk, everything came back, and LibreNMS also queries the device on SNMP the device just fine. Then I created a snmp netinventory task, I only added two device and an agent.
I would also send pictures, but unfortunately I can't find the description of attaching the picture to the forum. I don't have the storage space to link it from outside.
After that, I started a manual inventory from the agent's website.
Here is the log:

In practice, the snmp query has no results and thus no sense.
