Step 5
Open the crontab file in your system by entering crontab -e. The -e enables edit mode. You can run
crontab from any directory.
igloo:/ ->crontab -e
"/tmp/crontabmMaqZd" 14 lines, 610 characters
#ident "@(#)root 1.19 98/07/06 SMI" /* SVr4.0 1.1.3.1 */
#
# The root crontab should be used to perform accounting data collection.
#
# The rtc command is run to adjust the real time clock if and when
# daylight savings time changes.
#
10 3 * * 0,4 /etc/cron.d/logchecker
10 3 * * 0 /usr/lib/newsyslog
15 3 * * 0 /usr/lib/fs/nfs/nfsfind
1 2 * * * [ -x /usr/sbin/rtc ] && /usr/sbin/rtc -c > /dev/null 2>&1
30 3 * * * [ -x /usr/lib/gss/gsscred_clean ] && /usr/lib/gss/gsscred_clean
Caution
Although the crontab file is a flat text file, do not manually edit it by using vi crontab.
vi can corrupt the crontab, which causes all cron jobs to stop working. You must use the
crontab -e command, which synchronizes and updates all the crontab daemons
accordingly.
Step 6
Insert the directory path for the MRTG configuration file (.cfg) you created. At the bottom of the file,
enter a line similar to this one:
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /opt/mrtg/run/mrtg
/opt/mrtg/run/conf/travis-nas-01.cfg
Note
Do not forget to include a space between /mrtg and /opt
