Need help getting SNMP data from an OKI ES7470 MFP to Azure IoT

Hello Giacomo Maisano,

It sounds like you're trying to get SNMP data from your OKI ES7470 MFP printer into Azure IoT, and you’re looking for a script that can help with that. Here’s a general approach you can consider to pull the data and push it to Azure IoT.

Step-by-Step Guide

1. Set Up Your Environment:
   • Make sure you have an SNMP monitoring server configured. You'll need access to the printer's SNMP settings (IP address, community string, etc.).
   • Install any necessary tools on your server, like snmpget or snmptrapd, which are part of the Net-SNMP package. These tools are commonly used for SNMP operations.
2. SNMP Configuration:
   • Ensure the printer is set up to allow SNMP queries. You may need the MIB file for your printer if you want to pull specific data structured by OIDs.
   • You can find the OIDs for common metrics (like printer status, toner levels, etc.) in the printer's documentation.
3. Script to Pull SNMP Data:
   • Use a script written in a language like Python or Bash to poll the printer for data. Here’s a simple example in Bash:

     
          #!/bin/bash
     
          SNMP_COMMUNITY="your_community_string"
     
          PRINTER_IP="your_printer_ip"
     
          OID="1.3.6.1.2.1.25.3.5.1.1.1" # Example OID for printer status
     
          snmpget -v2c -c $SNMP_COMMUNITY $PRINTER_IP $OID
     
     

4. Push Data to Azure IoT:
   • Once you have the data, you can push it to Azure IoT using the Azure IoT Hub's REST API or MQTT protocol. Here’s an example using Azure IoT SDK for Python:

     
          from azure.iot.device import IoTDeviceClient
     
          connection_string = "HostName=<your-hub>.azure-devices.net;DeviceId=<your-device-id>;SharedAccessKey=<your-access-key>"
     
          client = IoTDeviceClient.create_from_connection_string(connection_string)
     
          # Send data
     
          data = {
     
              "status": "Your fetched SNMP data here"
     
          }
     
          client.send_message(json.dumps(data))
     
     

Additional Considerations

• Ensure any firewall rules allow SNMP traffic (usually on UDP port 161) to and from the printer.
• If you haven’t already configured your Azure environment (like setting up IoT Hub), make sure to do that.

Hope this helps!
Thank you!
