MRTG - CPU monitoring

Step 1

vi /etc/mrtg/mrtg.cfg

## CPU Load (user and system
Target[cpu]: ssCpuRawUser.0&ssCpuRawSystem.0:public@localhost
RouterUptime[cpu]: public@localhost
Title[cpu]: CPU Load
PageTop[cpu]: <H1>CPU Load (user and system)</H1>

### global options
LoadMIBs: /usr/share/snmp/mibs/UCD-SNMP-MIB.txt
Refresh: 300

Language: utf8
Options[_]: growright

First , you need "locate UCD-SNMP-MIB.txt" and modify in global options

indexmaker /etc/mrtg/mrtg.cfg > /var/www/mrtg/index.html
env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg
env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg
env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg

Generate new index page and update mrtg
