ARISTA Switch SNMP Checks

Hey Marius, I did some more adjustments and now I get the parsed values. Here is the code:

from .agent_based_api.v1 import *
def parse_arista_port(string_table):

    # print(string_table)
    # http://www.circitor.fr/Mibs/Html/E/ENTITY-SENSOR-MIB.php#EntitySensorDataType
    # Parse Sensor List into a dict

    sensors = {}
    for data in string_table[0]:
        sensorId = data[0]
        sensors[sensorId] = {
            "sensorType": data[1], 
            "sensorScale": data[2], 
            "sensorPrecision": data[3], 
            "sensorValue": data[4], 
            "sensorStatus": data[5], 
            "sensorUnit": data[6]
        }

    

    # http://www.circitor.fr/Mibs/Html/E/ENTITY-MIB.php#PhysicalClass
    # http://www.circitor.fr/Mibs/Html/E/ENTITY-MIB.php
    # Parse the Ports
    parsed = []
    for data in string_table[1]:
        deviceId = data[0]
        device = {
            'id': deviceId, 
            'desc': data[2], 
            'sensor': sensors.get(deviceId)
        }

        parsed.append(device)

    #print(sensors)
    print(parsed)
    return parsed

register.snmp_section(
    name = "arista_port",
    detect = startswith(".1.3.6.1.2.1.1.1.0", "Arista"),
    parse_function = parse_arista_port,
    fetch = [
        SNMPTree(
            base = '.1.3.6.1.2.1.99.1.1.1',
            oids = [
                OIDEnd(),
                '1', # entPhySensorType
                '2', # entPhySensorScale
                '3', # entPhySensorPrecision
                '4', # entPhySensorValue
                '5', # entPhySensorOperStatus
                '6', # entPhySensorUnitsDisplay
            ],
        ),

        SNMPTree(
            base = '.1.3.6.1.2.1.47.1.1.1.1',
            oids = [
                OIDEnd(),
                '1', # entPhysicalIndex
                '2', # entPhysicalDescr
                '3', # entPhysicalVendorType
                '4', # entPhysicalContainedIn
                '5', # entPhysicalClass
                '6', # entPhysicalParentRelPos
            ],
        ),
    ]
)

Here are some examples from the output. I think with that it is possible to write the check plugin or register the check plugin, but I am not sure how to proceed from here.

{'id': '1', 'desc': '48 SFP+ +4 QSFP 10Gb 1RU', 'sensor': None}, 
{'id': '100004002', 'desc': 'Scd Chip 2', 'sensor': None}, 
{'id': '100006001', 'desc': 'Cpu temp sensor', 'sensor': {
    'sensorType': '8', 'sensorScale': '9', 'sensorPrecision': '1', 'sensorValue': '412', 'sensorStatus': '1', 'sensorUnit': 'Celsius'}
},
