 Description   

Description:

  1. I used to have many network discovery rules running perfectly in Zabbix 6.0.31, for example:

  1. After I performed an upgrade from 6.0.31 to 7.0.3, the network discovery rules that had SNMPv2c checks stopped working.

Result:
See screenshot...

See proxy's log file...

And then:

I managed to contour the issue by changing the symbolic OIDs to numeric ones:

  • SNMPv2-MIB::sysDescr.0   =>  .1.3.6.1.2.1.1.1.0
  • SNMPv2-MIB::sysName.0  =>  .1.3.6.1.2.1.1.5.0

There's nothing in the manual stating that numeric OIDs must be used in SNMP checks.

I'm guessing that in version 7.0.3, zbx_snmp_translate() is not being called where and when it should be.
