Upgrade from MRTG to Cacti

 

Procedure:

  1. To begin the procedure you must Stop GCEMS if GCEMS is running

  2. There is a file named dialogicPRIMARYcron located at /opt/dialogic/IMG/GateControlEMS/bin. This file needs to have the reference to MRTG uncommented. Using either a vi editor or gedit uncomment the following line.

 

#*/5 * * * * env LANG=C /usr/local/mrtg/bin/mrtg /opt/dialogic/common/mrtg_bin/cantatamrtg.cfg -- logging /opt/dialogic/common/log/mrtg.log > /dev/null 2>&1

 

  1. The file should look like the following after being commented out. See bolded text

 

#######################################################################

#

# StartGCEMS was run in PRODUCTION/PRIMARY mode

#

######################################################################

# This script checks to see if each GCEMS component is running.

# If not, it is restarted.

#

* * * * * /opt/dialogic/IMG/GateControlEMS/bin/StartGCEMS -p -a > /dev/null 2>&1

#

# This script activates MRTG statistics gathering.

*/5 * * * * env LANG=C /usr/local/mrtg/bin/mrtg /opt/dialogic/common/mrtg_bin/cantatamrtg.cfg -- logging /opt/dialogic/common/log/mrtg.log > /dev/null 2>&1

#

# This script activates BACKUP File zip processing to happen daily at 12:30 AM.

30 0 * * * /opt/dialogic/IMG/GateControlEMS/bin/cantataBackupZip

#

 

  1. Located in /etc is a file named crontab. Using a VI editor or gedit utility comment out the reference to cacti. See file below with the line commented out

 

SHELL=/bin/bash

PATH=/sbin:/bin:/usr/sbin:/usr/bin

MAILTO=root

HOME=/

# run-parts

01 * * * * root run-parts /etc/cron.hourly

02 4 * * * root run-parts /etc/cron.daily

22 4 * * 0 root run-parts /etc/cron.weekly

42 4 1 * * root run-parts /etc/cron.monthly

#*/5 * * * * cactiuser /www/php/bin/php /www/htdocs/cacti/poller.php > /dev/null

2>&1

 

  1. Verify that Cacti has stopped logging by going to /www/htdocs/cacti/rra and checking the timestamps on the files. Verify they are not getting updated.

 

# cd /www/htdocs/cacti/rra

# ls -la

 

  1. Go to /opt/dialogic/IMG/GateControlEMS and edit the Defaults file using VI editor or Gedit so that the line stating Cacti support now reads CACTI_SUPPORT:0

 

 

  1. The Apache database must now be linked to MRTG instead of Cacti. Follow steps below to accomplish this. A link will be created linking Apache to MRTG

 

$ su

$ excel2 (root password)

# cd /www/htdocs

# ln -s /opt/dialogic/common/mrtg_logs  /www/htdocs/mrtg_logs

 

 

  1. In order to log into MRTG use the following link
