Login maker public @ localhost>/etc/mrtg. cfg

(Note) use the following command to monitor only one IP Address:
Registrant maker public@192.168.0.1>/etc/mrtg. cfg

Generate the home page of mrtg:
Indexmaker/etc/mrtg. cfg>/var/www/mrtg/index.html

Http: // localhost/mrtg/

2. Install CPU load monitoring [collection once every 5 minutes by default]

Switch to Super User:

#! /Bin/bash
Cpuusr = '/usr/bin/sar-u 1 3 | grep Average | awk {print $3 }'
Cpusys = '/usr/bin/sar-u 1 3 | grep Average | awk {print $5 }'
UPtime = '/usr/bin/uptime | awk {print $3 "" $4 "" $5 }'
Echo $ cpuusr
Echo $ cpusys
Echo $ UPtime
Hostname

Run the following script:
Chmod + 755/opt/mrtg. cpu

Modify/etc/mrtg. cfg and add the cpu project to the end of the file.

Switch to Super User:
Sudo-sH

Create a RAM script:
Mkdir/opt/mrtg
Vim/opt/mrtg. ram
#! /Bin/bash
# Run this script to check the mem usage.
Totalmem = '/usr/bin/free | grep Mem | awk {print $2 }'


Usef8 = '/usr/bin/free | grep Mem | awk {print $3 }'
UPtime = '/usr/bin/uptime | awk {print $3 "" $4 "" $5 }'
Echo $ totalmem
Echo $ usedmem
Echo $ UPtime
Hostname


Run the following script:
Chmod + 755/opt/mrtg. ram

Modify/etc/mrtg. cfg and add the ram project to the end of the file.
Target [ram]: '/opt/mrtg. ram'
# Unscaled [ram]: dwym
