Procedure:

  • To begin the procedure you must Stop GCEMS if GCEMS is running

  • 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
  • The file should look like the following after being commented out.

####################################################################### # # 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 #
  • 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
  • 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

  • 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

  • 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

  • In order to log into MRTG use the following link
    http://<IP ADDRESS OF GCEMS HOST>/mrtg_logs/systemindex.html
