Device
cisco(config)#
snmp-server community public RO
setup the
MRTG server
yum
install mrtg
-> will install the MRTG
yum install
httpd -> will
install the apache to view the graphs crated by mrtg
To configure
the MRTG issue following command:
Cfgmaker
–global “WorkDir: /var/www/mrtg” –output
/etc/mrtg/mrtg.cfg device-community-
string@( hostname
or IP)
in this
command :
--global “WorkDir: /var/www/mrtg” -> this is global configuration to define
where the graphs will be
store
- -output /etc/mrtg/mrtg.cfg
-> this is the output file
name
Now run the
indexmaker, that will create web pages which display the status:
indexmaker --output=/var/www/mrtg/index.html
/etc/mrtg/mrtg.cfg
As next step
you have to run following to gather the information and write into graphs:
LANG=C LC_ALL=C
/usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file
/var/lock/mrtg/mrtg_lock
Also you can
automate the run of MRTG by adding this command to cron job as followed. It
will run in every 5 minutes as scheduled.
