MRTG graph for FREERADIUS Online Users

Recently at a network where multiple NAS were implemented with single centralized billing system(radius Manager with Free radius as backend engine) , I had many mrtg base graphs for each NAS, and DUDE system to monitor various instances of the target systems, but there was no single graph to monitor overall ONLINE users of all NASES. MRTG was configured on main Billing ssytem, to sort this I used the following bash script and tag it with the mrtg cfg script.

.

SCRIPT TO PRINT ONLINE SESSIONS IN FREERADIUS

First create the script

mkdir /temp
touch /temp/online.sh
chmod +x /temp/online.sh
nano /temp/online.sh

Now paste the following code, [make sure to change the IP, ID and Password]

Note: I used this script for Radius Manager base freeradius billing system.

#!/bin/bash

SQL_USERNAME=radius_username
SQL_DATABASE=radius
SQL_PASSWORD=your_password
SQL_SERVER=127.0.0.1
SQL_ACCOUNTING_TABLE=radacct
BACK_DAYS=3

SESSIONS=`mysql -BN -u$SQL_USERNAME -p$SQL_PASSWORD -h $SQL_SERVER $SQL_DATABASE -e \
"SELECT COUNT(*) FROM $SQL_ACCOUNTING_TABLE \
WHERE acctstoptime IS NULL \
AND Acctstarttime > NOW() - INTERVAL $BACK_DAYS DAY;"`

echo $SESSIONS
echo $SESSIONS

Save & Exit.

.

MRTG.CFG FILE TO GENERATE MRTG GRAPH

Now create a MRTG cfg file and tag it with your master mrtg config file or run it as individual , its up to you and your local design.

#Radius.cfg
# Total Radius Users
Target[Radius.users]: `/temp/online.sh`
Title[Radius.users]: Central Billing System Logged in Users (Total)
PageTop[Radius.users]: <H1> Central Billing System  Logged in Users (Total)</H1>
MaxBytes[Radius.users]: 1000
Colours[Radius.users]: B#8888ff,B#8888ff,B#5398ff,B#5398ff
Options[Radius.users]: gauge,nopercent,noo,integer,growright
LegendI[Radius.users]: Radius Logged in Users
LegendO[Radius.users]:
YLegend[Radius.users]: Radius Logged in Users/Total
Legend1[Radius.users]: Radius Logged in Users/Total
Legend2[Radius.users]:
Unscaled[Radius.users]: ymwd

I will post the radius online users graphs tomorrow I.A
