CMK version: 2.4.0p16 Enterprise
OS version: Debian Linux 12.12
I have created a simple SNMP-plugin, which only monitors one single value:
#!/usr/bin/env python3
from cmk.agent_based.v2 import *
def check_if_lte_up(section):
if_lte_up = int(section["if_lte_up"])
if(if_lte_up != 1):
yield Result(state=State.CRIT, summary="LTE-Verbindung ist gestört")
else:
yield Result(state=State.OK, summary="LTE-Verbindung ist aufgebaut")
def discover_generic(section):
yield Service()
check_plugin_oneaccess_if_lte_up = CheckPlugin(
name = "oneaccess_if_lte_up",
sections = ['oneaccess_data'],
service_name = "Interface LTE",
discovery_function = discover_generic,
check_function = check_if_lte_up,
)
def parse_oneaccess_data(string_table):
section = {}
section["if_lte_up"] = string_table[0][0]
return section
snmp_section_oneaccess_data = SimpleSNMPSection(
name = "oneaccess_data",
detect = contains(".1.3.6.1.2.1.1.1.0", "OneOS-pCPE-ARM_pi1-6.14.2m2"), # sysDescr
fetch = SNMPTree(
base = '.1.3.6.1.2.1.2.2.1.8',
oids = [
'402657280' # if_lte_up
],
),
parse_function = parse_oneaccess_data,
)
I copied the py-file to local/lib/python3/cmk_addons/plugins/oneaccess/agent_based/oneaccess.py.
When manually executing
cmk --detect-plugins=oneaccess_if_lte_up --debug -vvv Host-to-monitor the test is succesful:

When restarting (cmk -R) monitoring core, the service is visible in GUI and seems to work.
But after some time, the service changes to “Unimplemented check oneaccess_if_lte_up”. Does anybody know what I am doing wrong?
