Network Discovery and Network Inventory SNMP not works for me.

ramses.sevilla · 2020-07-08 14:33:43

Hi everyone,

I have installed a server with GLPI 9.4.6 + FusionInventory 9.4+2.4 over UBUNTU Server 20.04 and
FusionInventory-Agent 2.5 on computers and It works well, I can see the assets Computers.

Now I need discover the Network Devices (Routers, Switches, Printers,...) by SNMP.

I have installed the FusionInventory-Agent on the Server and I have configured FusionInventory Network Discovery following this process:
http://fusioninventory.org/documentatio … overy.html

I think that all is configured fine but don't work.

If I check the tasks in the Agent it show me the next:

-------------------------------------------------
glpi@glpi:~$ sudo fusioninventory-agent --list-tasks
Available tasks :
Inventory (v1.9)
WMI (v0.3)
Maintenance (v1.1)
NetInventory (v4.1)
WakeOnLan (v2.2)
NetDiscovery (v4.1)

server target: https://glpi.test.com/plugins/fusioninventory/
Planned tasks:
- Inventory (v1.9)
- NetDiscovery (v4.1)
- NetInventory (v4.1)

scheduler target: scheduler0
No planned task
glpi@glpi:~$
-------------------------------------------------

If I look into Networking > Network Inventory Status It does not show any task.

The FusionInventory-Agent Service is running correctly:

--------------------------------------------------
glpi@glpi:~$ sudo systemctl status fusioninventory-agent.service
[sudo] password for glpi:

--------------------------------------------------

What I can be doing wrong?

Do I need define a rule or something to works Network Discovery and Network Inventory SNMP?

Regards,

Ramsés

You need to set task. First - discovery to find devices. When you will find it - you can inventory by SMTP.

1. Administration > Fusioninventory > Networking > SNMP credentials > plus to add your SNMP settings (ex. for your switches).
2. Administration > Fusioninventory > Networking > IP Ranges > plus to add your IP ranges where you have ex. switches. When you will add this range you have to open it and on "Associated SNMP credentials" tab - add SNMP setting from point 1.
3. Administration > Fusioninventory > Tasks > Task Management > plus to add task (discovery). At the "jobs configuration" tab of this task - set targets (IP range from point 2) and actors (ex. agent installed at the computer).
4. Go to https://computerIP:agent_port and click Force inventory.
5. Administration > Fusioninventory > Networking > Discovery status > check results.

Hello I am also having troubles to set up the network inventory via SNMP. Following the steps you mention:

1: I just assigned SNMP v3 credentials for read-only - should be enough, to import network printers?
2: I have added the two IP ranges of interest, to which I assigned the SNMP v3 credentials from step 1
3: I have added a discovery task and added the IP ranges from step 2 as targets, my PC agent as actor
4: I click force Inventory, runs fine
5: But Nothing shows up under Discovery status, no devices imported

Do you have a guess what I might be doing wrong?

Strangely, under computer's network names tab -> "HomeSetup Dropdowns Network names" I see the warning: IP networks - "IP network is not included in the database. However, you can see current available networks"
but nothing happens when I assign one of my IP networks. Is this a bug?

Any help appreciated.

Best Regards

Personally, I couldn't get HP printers to work with SNMP version 3 With lower version... hard to say with my poor English. It would be easier with the screenshots.

Did you check the DiscoveryTask status?: plugins/fusioninventory/front/statediscovery.php (Devices not imported? Devices linked? Devices imported?)
If you have "Finished tasks" than you should check: plugins/fusioninventory/front/ignoredimportdevice.php

You cannot import devices via SNMP. This task is for inventory. But first you have to discovery devices.
Therefore, you need to create 2 tasks - the first for discovering (and adding devices to the database) and the second - SNMP inventory.

Maybe try SNMP v1 / v2 and 1 or 2 printers first? If this works, you will know if it is a problem with the SNMP version or the job configuration.

Hi everyone

I've the same problem with SNMPv2
I've a server Linux (kali) with IP 192.168.100.100 where I installed GLPI 10.0.6 and GLPI agent 14.1.
I linked the server Linux with a Cisco router (IP: 172.16.0.1 ).
I would like to add Cisco router in GLPI inventory and populate the inventory with SNMPv2. I can't install the GLPI agent in the Cisco router.

The comunication between server and Cisco router work. I ping Cisco router from server Linux and SNMP work correctly, I tested it with snmwalk.

(root㉿kali)-[~]# ping 172.16.0.1

.....
.

I used the plugin "GLPI Inventory" for this goal and I created the two tasks, but didn't work
I tried with FusionInventory but nothig is changed.

The two tasks are:

1) Create first task for discover the network devices

In Administration -> GLPI Inventory -> IP Ranges
I created IP range with name "network" ( 172.16.0.1 - 172.16.0.255) and associated it with SNMP credentials ( v2, community: public )

In Administration -> GLPI Inventory -> Task management
I created task "Discover" and in "Job configuration" I associated Object "network" and actors GLPI agent 14.1, then I activated this task in "task managment" and I clicked on "Force start"

2) Create second task for SNMP:

In Administration -> GLPI Inventory -> Task management
I created task "SNMP" and in "Job configuration" I associated Object "network" and actors GLPI agent 14.1
I activated this task in "task managment" and I clicked on "Force start"

Finally I went to htp://127.0.0.1:62354 and I clicked on Force Inventory

In Administration -> GLPI Inventory -> GLPI Inventory I see only the one device, the server Linux but the Cisco router no.
I activated the agent in Administration -> GLPI Inventory -> General setup -> Agents modules

what is the problem?
