SNMP Inventory shows "No data available in table"

• OS Name : Linux x86_64
• Version : 5.3.18-lp152.72-default
• RAM installed : 3892 MB
• Free RAM : 3082 MB
• Distribution : openSUSE Leap 15.2
• PHP Version : 7.4.6
• Web Server : Apache
• Database Server : MariaDB package version 10.4.17-MariaDB
• Version OCSReports: 2.8.1
• Agent Version: 2.8.1
• Agent and Server installed from source

Problem: Inventory --> SNMP = "No data available in table"

Expected result: OCS would scan a host with snmp enabled (192.168.209.134) and add it to the Inventory --> SNMP

My setup has two hosts:

• openSuse with OCS Server installed
• ubuntu with snmp enabled
• Both in the 192.168.209.0/24 network

From command line on the openSUSE server side is possible to view the snmp info from ubuntu:

snmpwalk -v2c -c public 192.168.209.134 1.3.6.1.2.1.1.5

SNMPv2-MIB::sysName.0 = STRING: ubuntu-testes

OCS server is setup to scan snmp like this:

• Configuration --> General
  • --> SNMP
    • SNMP Enable/Disable the snmp service: ON
  • --> Ipdiscover: ON
• Manage --> Network Scan
  • SNMP communities --> 
    • Version: 2c
    • Name: public 
• Configuration --> SNMP
  • --> Create type:
    • Name: host
    • OID Value: 1.3.6.1.2.1.1.5
    • Value: sysName
  • --> Create label:
    • Name: name
  • --> Type configuration
    • Type: host
    • Label: name
    • OID: 1.3.6.1.2.1.1.5
    • Use for reconciliation: yes
  • --> Add MIB File: not configured
• All computers --> Select localhost (that is the current openSuse ocs server)
  • --> Configuration --> Edit --> Netowrks scans
    • Ipdiscover: 192.168.209.0
    • Snmp_Switch: ON
    • Snmp_Networks 192.168.209.0/24

Server Agent config:

tag=ocs-server

debug=1

logfile=/var/log/ocs-agent.log

server=https://192.168.209.136/ocsinventory

snmpretry=2

snmp=1

nosoftware=0

basevardir=/var/lib/ocsinventory-agent

snmptimeout=3

ca=/etc/ocsinventory-agent/cacert.pem

The server is accessible via https, no cert erros on the ocs agent log

Quering DB show nothing on the snmp table (snmp_host because of the created type host)

MariaDB [ocsweb]> SELECT * FROM snmp_host;

Empty set (0.000 sec)
