About my network inventory issues

Only thing I want is to inventory my network devices via SNMP without configure each field of information. That is a slave work. Unfortunely GLPI documentation doesnt give a clear example of how to do this. Could you please give me a hand and explain me how to execute a glpi-netinventory scan (for a given host, like 10.7.100.3) and import this information to my GLPI server?

I am using:

glpi-agent_1.6.1
glpi-agent-task-network_1.6.1
OS: Ubuntu 20.04
Server: glpi-10.0.10
Aditional info: The agent is installed on same GLPI server and the server has access to isolated network for network devices, through VPN. Network devices are under 10.7.100.0/24, while GLPI server is glpi.ecasa.avianet.cu. The agent config is as follow:

server = https://glpi.ecasa.avianet.cu/marketplace/glpiinventory
delaytime = 3600
lazy = 0
scan-homedirs = 0
scan-profiles = 0
html = 0
backend-collect-timeout = 180
force = 0
additional-content =
no-p2p = 0
proxy =
user =
password =
ca-cert-dir =
ca-cert-file =
no-ssl-check = 1
timeout = 180
no-httpd = 1
httpd-ip =
httpd-port = 62354
httpd-trust =
logger = stderr
logfile = /var/log/glpi-agent.log
logfacility = LOG_USER
color = 0
tag =
debug = 0

Theglpi-netdiscovery does not create the folder netinventory inside the glpi-agent config directory. It just created the netdiscovery folder. Your first command with netinventory does not create a netinventory folder, it just create a file specified for output. In my case:

glpi-netdiscovery --host 10.7.100.3 --credentials version:2c,community:ecasanc --timeout 30 --inventory --save /etc/glpi-agent/ --debug

Created the file 10.7.100.3.xml

cat /etc/glpi-agent//netdiscovery/10.7.100.3.xml

Its contents is as follow:

But when used glpi-netinventory command:

glpi-netinventory --host 10.7.100.3 --credentials version:2c,community:ecasanc --timeout 30 --type NETWORKING --debug > 10.7.100.3.xml

It only created the file 10.7.100.3.xml on your root directory, not inside the agent folder as expected (it can be fixed specifying the complete path, but you still have to create the netinventory folder first)

Anyway, the output of the previous command is as follow:

[debug] Current netinventory run expiration timeout: 1.0 hour
[debug] using 1 netinventory worker
[debug] #1, full snmp scan of 10.7.100.3 with credentials 1
[debug] #1, full match for sysobjectID .1.3.6.1.4.1.2011.10.1.43 in database

When you check the file 10.7.100.3.xml, is empty.

I can execute an snmpwalk to the network device:

snmpwalk 10.7.100.3 -v2c -c ecasanc | less

The output is as follow:

iso.3.6.1.2.1.1.1.0 = STRING: "Huawei Versatile Routing Platform Software

Trying again with glpi-netinventory command, this time more simple:

glpi-netinventory --host 10.7.100.3 --credentials version:2c,community:ecasanc

The output show error communication via SNMP using the agent:

[error] #1, SNMP communication error: no response from host 10.7.100.3
<?xml version="1.0" encoding="UTF-8"?>
<REQUEST>
  <CONTENT>

    <PROCESSNUMBER>1</PROCESSNUMBER>
  </CONTENT>

Why is not working the netinventort using the agent, when snmpwalk is able to query the remote network device using this protocol?
