Hello,
Friends,
I dont have much experience in snmp configuration so decided to ask smarter people 
I’m having a problem with adding mcafee atd device via snmp protocol.
Snmp worked fine with other vendors, but seems like this one is not being recognized properly as its not giving any system information on query .1.3.6.1.2.1.1
$cmk --debug -v -I ATD
[snmp] ERROR: Cannot fetch system description OID .1.3.6.1.2.1.1.1.0. This might be OK for some bogus devices. In that case please configure the ruleset “Hosts without system description OID” to tell Check_MK not to fetch the system description and system object OIDs.
$ snmpwalk -On -v2c -c ** x.x.x.x
.1.3.6.1.2.1 = No Such Object available on this agent at this OID
Host connection is not an issue as I managed to discover all available OIDs on the atd device:

…but have no clue how to implement it on check_mk as my atd’s services. I also have a mib file with the description. Been playing a little with python files based on instruction found on https://checkmk.de/cms_legacy_devel_snmpbased.html but with no luck 
v. raw v.1.6.0p5
Will be grateful for any help.
Regards.
