After applying custom plugins, checkmk is display UNKNOWN state

glumauig · July 9, 2024, 11:41pm

Hi,

I am creating a custom plugins for an SNMP card which monitors our HVAC. After doing the following commands, there was no error on CLI however in CHeckmk dashboard it shows UNKNOWN state. Can anyone help me on this issue?

cmk --detect-plugins=hvac_C2 -vl hvac-2
cmk --debug -II --detect-plugins=hvac_C2 -vl hvac-2
cmk -vv --debug --detect-plugins=hvac_C2 hvac-2

These are the code

import re
from .agent_based_api.v1 import *
from cmk.base.plugins.agent_based.agent_based_api.v1 import (
   get_value_store,
)

def discover_hvac_C2(section):
    yield Service()

def check_hvac_C2(section):
    hvac_snmp_C2 = int(section[0][0])
 
    ##Compressor 1
    if hvac_snmp_C2 == 0:      
        hvac_snmp_value_converted = "Off"
        summary_hvac_C2 = "Compressor2 Status: " + str(hvac_snmp_value_converted)
        #yield Result(state=State.OK,summary=summary_hvac_C2)

    else:
        hvac_snmp_value_converted = "On"
        summary_hvac_C2 = "Compressor2 Status: " + str(hvac_snmp_value_converted)
        #yield Result(state=State.CRIT,summary=summary_hvac_C2)
    
    yield Result(state=State.CRIT,summary=summary_hvac_C2)
    hvac_snmp_C2_name = "Compressor_Status"
    yield Metric(hvac_snmp_C2_name,hvac_snmp_C2)

    

register.snmp_section(
    name = "hvac_C2",
    #detect = contains(".1.3.6.1.2.1.1.1.0","licheepi-zero"),
    detect = exists(".1.3.6.1.4.1.7416.1.2.30019.0"),
    fetch = SNMPTree(
        base = '.1.3.6.1.4.1.7416.1.2',
        oids = ['31.0'],
    ),
)

##register plugins
register.check_plugin(
    name = "hvac_C2",
    sections = ["hvac_C2"],
    service_name='HVAC Compressor 2',
    discovery_function= discover_hvac_C2,

If you want to simulate the real check i would test with

cmk -vv --debug hvac-2

I think your detect OID works not correctly.
With the “–detect-plugins” you overrule this part.

I run the debug file here is the result.

You need to check with “snmpget” for the detect OID.
In your code you have another OID →

My bad it should be .30016.0
I changed my OID detect however it still the same. Still “Check plugin received no monitoring data”

Relevant is first the detection without the “force”.

cmk --debug -vvII hvac-2

After the “SNMP scan” the line is relevant where you see the found plugins.

Is it possible that you have a rule active that disables nearly all SNMP sections?
It’s a little bit short, the scan.

glumauig · July 11, 2024, 9:24pm

Yes, Actually i worked with cmk support because the snmp card has some limited allowable oid that can be scanned and since cmk is doing all snmp section by default, cmk tends to timeout which causes not to detect snmp_uptime and interface. hence they recommend to allow only interface and snmp_uptime.
What should I allow in snmp section in order for the script to detect the custom OID?

thl-cmk · July 11, 2024, 9:40pm

your own section hvac_C2 maybe ?

glumauig · July 11, 2024, 9:48pm

No, hvac_c2 is a actually the plugin I created.

andreas-doehler · July 12, 2024, 3:39am

glumauig:

register.snmp_section(
    name = "hvac_C2",
    #detect = contains(".1.3.6.1.2.1.1.1.0","licheepi-zero"),
    detect = exists(".1.3.6.1.4.1.7416.1.2.30019.0"),
    fetch = SNMPTree(
        base = '.1.3.6.1.4.1.7416.1.2',
        oids = ['31.0'],
    ),
)

Here is your section with the name that @thl-cmk said.
You need to enable this section to be found for your device.

glumauig · July 12, 2024, 4:52pm

@andreas-doehler and @thl-cmk thank you both for your input. Yeah this fix my issue.
really appreciate your quick responses!
