How to create (upload/download) graph for devices connected to router/switch using Cacti?

I am trying to create the graph for the ONU (client end) devices connected to the Optical Line Terminal(OLT) . The graph for OLT(upstream) can be created but Im stuck on creating graphs for every devices connected to OLT.

Solution

  • Got it working : The DataInputMethod should be script/command. Script to get OLT snmp data and output them to file [ I run this script using cron every 2 minutes ] The data is saved to respective OLT files in /tmp directory.

    Later I use another script to extract the ONU (client side device connected to each OLT to extract download and upload data)

    # get_olt_snmp.sh

#!/bin/bash
echo ` date`
