Custom SNMP plugin, works via cmk, services vanish via WATO

If you use the “–checks” option, you will ignore the scan function.

Ooooh, I wasn’t aware of that. Thanks.

Here’s my scan function (directly copy-pasted from the check_info structure):

    'snmp_scan_function':  lambda oid:
            oid(".1.3.6.1.2.1.1.2.0").startswith(".1.3.6.1.4.1.674") \
                        and 'me4' in oid(".1.3.6.1.2.1.1.1").lower(),

and after trying both OIDs shown I can easily see my mistake: the second one is too short, should be .1.3.6.1.2.1.1.1.0. Changed to

    'snmp_scan_function':  lambda oid:
            oid(".1.3.6.1.2.1.1.2.0").startswith(".1.3.6.1.4.1.674") \
                        and 'me4' in oid(".1.3.6.1.2.1.1.1.0").lower(),

and a “full scan” in WATO instantly starts to work on both hosts.

Thanks a lot! Solved!

For the record:

.1.3.6.1.2.1.1.2.0 = OID: .1.3.6.1.4.1.674
.1.3.6.1.2.1.1.1.0 = STRING: "DELL EMC ME4024"

For the Powervault ME4 i wrote last week a special agent for the well documented REST Api.

Very nice! I’ll gladly give it a try once it’s out. Where should I look for a release announcement?
