Adding support to LibreNMS for WUT thermometers 57605 and 57614

[Ervin_Skendaj]

hey guys , im trying to add support to LibreNMS for the WUT thermometers version 57605 and 57614.
this is my validate.php
bash-5.1$ php validate.php

Component	Version
LibreNMS	22.6.0-2-g1056f28de
DB Schema	2021_02_09_122930_migrate_to_utf8mb4 (242)
PHP	7.4.30
Python	3.9.10
MySQL	10.5.13-MariaDB
RRDTool	1.7.2
SNMP	5.9.1

====================================

[OK] Composer Version: 2.3.7
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database Schema is current
[OK] SQL Server meets minimum requirements
[OK] lower_case_table_names is enabled
[OK] MySQL engine is optimal
[OK] Database schema correct
[OK] MySQl and PHP time match
[OK] rrd_dir is writable
[OK] rrdtool version ok

now the issue is :
i’ve collected all the snmp-data via these commands:

php /opt/librenms/scripts/collect-snmp-data.php --full -o wut -v 57605 -h themometer1
php /opt/librenms/scripts/collect-snmp-data.php --full -o wut -v 57614 -h themometer2

but when i generate the .json file , there is no section that has enclose the sensors…

running this command :
php /opt/librenms/scripts/save-test-data.php -o wut -v 57605 -m sensors -d

php /opt/librenms/scripts/save-test-data.php -o wut -v 57614 -m sensors -d

even if i run the commands without -m , same result , the .json files have no sensor section created.

i’ve aslo uploaded the mibs for the respective devices, and renamed them as standard requested.

i don’t know what im doing wrong …any help would be welcomed.
thanks again.
Ervin.

i’ve changed the wut.yaml file, in order to get from the thermometers what i need:

this is what my yaml file looks like:

mib: WebGraph-Thermometer-PT-MIB:WebGraph-Thermometer-NTC-MIB:WebGraph-Thermometer-MIB:WebGraph-8xThermometer-MIB:WebGraph-2xThermometer-MIB
modules:
sensors:
temperature:
options:
divisor: 10
data:
-
oid: wtWebioAn1GraphTemp
value: wtWebioAn1GraphBinaryTempValue
num_oid: ‘.1.3.6.1.4.1.5040.1.2.{{ $index }}’
descr: ‘Temperature’
index: wtWebioAn1GraphSensorEntry.{{ $index }}

now the issue is that at the initial discovery via this command :
php discovery.php -h thermometer1 -m sensors -d
php discovery.php -h thermometer2 -m sensors -d

i get the values from the sensors , the graph is being created (empty)
but minimum / max/ and current value remain always 0.

and here it shows for a moment the real temperature , then it gets back to 0

this is from manual discovery.php :

php discovery.php -h thermometer1 -m sensors -d

SQL[SELECT * FROM sensors AS S, devices AS D WHERE S.sensor_class=? AND S.device_id = D.device_id AND D.device_id = ? AND S.poller_type = ? [“count”,158,“snmp”] 0.2ms]

hi guys , can someone give me a hint why this is happening :
im running the following command:
./poller.php -r -f -p -d -h thermometer1

SNMP[’/usr/bin/snmpget’ ‘-M’ ‘/opt/librenms/mibs:/opt/librenms/mibs/wut’ ‘-v1’ ‘-c’ ‘COMMUNITY’ ‘-OQXUte’ ‘-t’ ‘5’ ‘-r’ ‘10’ ‘udp:HOSTNAME:161’ ‘SNMP-FRAMEWORK-MIB::snmpEngineTime.0’ ‘HOST-RESOURCES-MIB::hrSystemUptime.0’]

then

Checking (snmp) temperature …
0 C

setting the temperature , as 0 , when i do an initial discovery the temperature shows correnctly for around 1min 45 sec (or less) and then it switches to 0 C.

i’ve downloaded the MIB files from the provider’s website. also i’ve updated the yaml file (actually adapted to my case) and as i said it gets the initial value , then it switches to 0.

i can see also this warning
