SNMP Check Switch Interface Alias

Troubleshooting
9

I was able to create a new check for the moxa switch. It is basically a copy and paste from the already existing checks if64 and if64_tplink

It is working, but not usable for all moxa switches because the vendor ifAlias ID is different for every switch series (.1.3.6.1.4.1.8691.7.18.1.9.1.1.7 EDS-G509) (.1.3.6.1.4.1.8691.7.7.1.9.1.1.7 EDS-408A)

So for a check to work for all moxa switches it would be necessary to determine the correct OID for the switch inside the check.
Because we only use this two types I just created two checks one for each switch series.

Here is the code, maybe it helps someone else…

#!/usr/bin/python

@network_interface_scan_registry.register
def snmp_scan_function_if64_moxa(oid):
return oid(".1.3.6.1.2.1.1.2.0").startswith(".1.3.6.1.4.1.8691.7.18")

def inventory_if64_moxa(info):
return inventory_if_common(info, has_nodeinfo=True)

def check_if64_moxa(item, params, info):
return check_if_common(item, params, info, has_nodeinfo=True)

Thanks for the quick responses, this solves the problem for my environment :slight_smile:
