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

Question

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.

Answer 1

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`

Read onu script to create graph for each client end device.Add this script in cacti datainputtype field

# read_onu_snmp.sh

#!/bin/sh
#
# Find a user's in/out traffic by username.
# Syntax:
# olt_snmp <olt> <ontid>

OLT=$1
ONTID=$2

UPLOAD=`/bin/grep ${ONTID} /tmp/${OLT}_upload_data | cut -d':' -f4 | sed 's/ *//g'`
DOWNLOAD=`/bin/grep ${ONTID} /tmp/${OLT}_download_data | cut -d':' -f4 | sed 's/ *//g'`

echo "in_traffic:${UPLOAD} out_traffic:${DOWNLOAD}"
