Displaying sensor data from yaml file

Help
1

Hi,

This is my first time posting so if this question has already been asked or if this is not posted in the correct area I am sorry.

My issue is that I have been unable to display sensor information from a yaml file that I created. I have looked through the discovery and all of the data is there but I am unable to display that info. At this point I am lost. Everything that I have found shows that I am doing it correctly or at least I think I am. Any help would be great. Thanks

----------------------------------------aen.yaml---------------------------------------------

mib: ACD-SFP-MIB

modules:
   sensors:

       dBm:
           data:
                 -
                   oid: acdSfpDiagRxPwrdBm
                   num_oid: '.1.3.6.1.4.1.22420.2.4.2.1.9.2'
                   descr: 'Rx'

----------------------------------------Debug Discovery-----------------------------------

#### Load disco module sensors ####
Caching data: sensors SNMP['/usr/bin/snmpbulkwalk' '-v2c' '-c' 'COMMUNITY' '-OteQUs' '-Ih' '-m' 
'ACD-SFP-MIB' '-M' '/opt/librenms/mibs:/opt/librenms/mibs/accedian' 'udp:HOSTNAME:161' 
'acdSfpDiagRxPwrdBm']

acdSfpDiagRxPwrdBm.1 = "-6.57 dBm
"
acdSfpDiagRxPwrdBm.2 = "-10.49 dBm

The num_oid is not correct.
You should check it, AND add .{{ $index }} at the end.

do a ./poller.php -h -m sensors -v -d and the error will be visible.

I added .{{ $index }} but I can’t find how the num_oid is not correct. It is discovering the correct data just not displaying the sensor. I ran ./poller.php -h -m sensors -v -d but i didn’t get any errors. Is there anything that needs to be added to the yaml file for it to display the sensor?

Basic procedure is :

  • Find your textual OID you want to draw
  • snmptranslate it to the numerical value
  • snmpwalk that numerical value to identify the OID and the INDEX
  • put the textual OID in ```value: ````
  • put the numerical OID in num_oid: with .{{ $index }} at the end

If the polling succeed in cli, you’ll get the graphs after at least 2 poll intervals.
