Hi,

How i can monitor temperature from my GPON ZTE C300 / C320?

OID: .1.3.6.1.4.1.3902.1015.2.1.3.2

Regards,
W.

Support needs to be added, please see this as an example : https://github.com/librenms/librenms/blob/master/includes/discovery/sensors/temperatures/ies.inc.php

<?php echo(" ZTE-AN-EQUIP-MIB "); // Chassis temperature $high_limit = 65; $high_warn_limit = 55; $low_warn_limit = 15; $low_limit = 5; $descr = "GPON ZTE Temperature"; $oid = ".1.3.6.1.4.1.3902.1015.2.1.3.2"; // extremeCurrentTemperature $value = snmp_get($device, $oid, '-Oqv', 'ZTE-AN-EQUIP-MIB'); if (is_numeric($value)) { discover_sensor($valid['sensor'], 'temperature', $device, $oid, 1, 'ztegpon-temp', $descr, '1', '1', $low_limit, $low_warn_limit, $high_warn_limit, $high_limit, $value); OK, what's now?

The code is at least missing a closing }

Have you tested it?

Hello, i’m have this device. (C320). What steps i need to add support of them? Have some linux/snmp/php skills, but not have MIBs.

I want to add OLT/ONU GPON ports with optical rx/tx and link-length information.
I found some oids to do that, but how to discover these “virtual” xPON interfaces in LibreNMS?

6

Got MIBs for these GPON devices, did’n test yet

@111 Have a look at the documentation on adding device support :
https://docs.librenms.org/Support/Adding-a-Device/

I can’t figure out how to work with ONU GPON interfaces. They have a completely different ideology, not like IF-MIB. Standart IF-MIB covers only GPON OLT interfaces. But each OLT interface can contain up to 128 ONU interfaces (end user devices) that needs to be discovered and polled: Rx/Tx Dbm, Rx/Tx bytes, Optical cable length, ONU statuses and others

…

The values like 268501248 in OID tree are encoded ONU “address”
gpon-onu-1/2/3:4 - is RACK 1, SHELF 2, OLT PORT 3, ONU NUMBER 4

I know algorithm to encode this value

function encode_gponOnuIndex($shelf=“0”, $slot=“0”, $port=“0”, $onu_num=“0”) {
return( (1 << 30) + (($shelf -1 ) << 21 )+ (($slot - 1) << 20 )+ ( ($port - 1) << 16 )+ ( ($onu_num - 1 ) << 8 ));
}

I would do this type of discovery using LibreNMS “Components” which are a generic way of storing data and polling it. Standard Interface is tighlty linked to IF-MIB and would not be adapted for anything else.
Using Components, you could do a discovery phase (with a new module), a polling phase (again with a new module) and create new WebUI to display this data.

OSPF neighbors are an example of this “Component” usage.

Hi, do you found how to graphs traffic onu interface from OLT?

Hi, what software do you use to graph bandwith per ONU bro?

13

Hi bro, so, do you have what are the OID to Output rate and Input rate ?,

thanks!

Hi, i’m testing my code…
BTW, i’m added temperature, cpu, memory, ONU/OLT RX dbm

Next, i will try to discover ONU as Interface of OLT, with bandwith and errror counters
Then, i will ask help to push my code to librenms thru GIT

Hi there.

Just a tip: If you want to add ONU data (sensors, interfaces, etc) I would make that optional creating a module.

Why? Think in a OLT with, lets say, 300 ONUs. That means you will have a device overview with 300+ sensors that will need to load. And now think in a OLT with 3k ONUs.

I dont own a ZTE but Huawei ones. In my case, polling ONU info would multiply no less than x10 my current sensor count in LibreNMS. And thats only with 1 sensor (ONU RX).

That would kill my current install totally :wink:

Hi Guys!, thanks for your comments!, so, I need only to graph bandwidth for ONU. could you give a example how I need to configure the template to do it please?, Right now I am using Cacti, but I need to improve discovery ONU, because I am configuring one by one ONU OID (Tx, Rx) :woozy_face:.

And how to understand how for the next gpon-onu_1 / 1/1: 2, etc.

Hello, sorry to post on an old thread, but can you tell me the OID to get the Power Levels of the ONUs?

Thank you

Hi, do you have this changes in a github tree?

are those based on the 1.2.5 MIB, of you somehow found the 2.1.0 MIB? :slight_smile:

Hello how did you manage to put in cpu and memory graphics from zte
