I have a plugin which is working in CheckMK 2.3 but I can’t work out how to get it work in CheckMK 2.4

#!/usr/bin/env python3

from cmk.base.check_api import LegacyCheckDefinition
from cmk.base.config import check_info

from cmk.agent_based.v2 import any_of, SNMPTree, startswith, StringTable

def inventory_sbc_signalling(info):
    inventory = [] 
    for line in info:
        inventory.append( (line[0], None, None) )
    return inventory

def parse_sbc_signalling(string_table: StringTable) → StringTable:
    return string_table

def check_sbc_signalling(name, params, info):

for label, enabled in info:
    if name == label:
        infotext = "Signal %s " % label
    if int(enabled) == 1:
        return (0, “OK - %s” % infotext)
    else:
        return (2, “CRITICAL - %s” % infotext);

check_info[‘sbc_signalling’] = LegacyCheckDefinition(
parse_function=parse_sbc_signalling,
discovery_function=inventory_sbc_signalling,
check_function=check_sbc_signalling,
service_name=“Signal %s”,
detect=any_of(
startswith(“.1.3.6.1.2.1.1.2.0”, “.1.3.6.1.4.1.177.15.1.1”),
),
fetch=SNMPTree(
base=“.1.3.6.1.4.1.177.15.1.5.4.1”,
oids=[“2”, “5”],
),
)

The device is a session border controller and it used for our telephony system

The oid .1.3.6.1.4.1.177.15.1.5.4.1.2 is a string, the name of the signal

I did finish the article on inventory plug-ins but did not yet add it to the TOC:
