On the left side of the Console screen under the Management Heading there is a field named Data Sources. Click on it. A screen like the following will appear:
The screen above shows all the Data Sources that are available in Cacti by default for the localhost. These are all Datasources for the GCEMS server you are logged on to.
In order to get the IMG data to be part of this list you must start GCEMS.
Once GCEMS is started then all the information from the /opt/dialogic/common/stats directory will now be sent to the RRDTool and from there will be sent to cacti to graph. In the above left corner of the screen above under "Select a Host" choose Any and the graphs set up for the IMG and the GCEMS will appear. See below.

The stats file is queried every 5 minutes which is the default set up in GCEMS. It may take up to 5 minutes for the graphs to appear in the menu above. The interval in which the stats file is updated is configured in the Defaults file located at either /opt/dialogic/IMG/GateControlEMS. (Software 10.5.1+) Edit the line STATS_FREQUENCY:5 to change the interval |

Click on the graphs tab at the top of the page. All the graphs from the screen shot above will appear in graphical form. On the left side of the screen is a graph tree and on the right side are the graphs.
Each of the graphs in the Data Source field can be configured individually. E-mail alerts and threshold values can be configured for each graph. In the Data Sources screen above double click on one of the graphs under the Template Name field and a screen like below will appear
Within this screen whether a Data Source is enabled or not is configured. Most of the thresholds in the Data Source Items screen are self explanatory. Below are some notes on these fields
CDEF Threshold - CDEF's allow you to apply mathematical functions to graph data to alter output
Send notifications to default alert addresses - This determines which set of email addresses will be used for alerting. There are individual addresses and global addresses. Individual addresses means that each individual threshold has a separate email address to send alerts to that are configured in the Alert E-Mail field above. Global means to send emails from all Data Sources to a specific set of emails predetermined by the user. For simplicity set this to Force:Off. This way you will only need to keep track of email address for the Alert E-mail field
Store a comma delimited list of email addresses that will be alerted if this threshold is exceeded
...
One other field that should be mentioned is the Settings field under Configuration. If you click on the Settings field and then the Alerting/Thold tab the following screen below will appear.
This is the global screen for setting email alerts and thresholds. From this page an alerting email will be sent if any of the thresholds are exceeded. Also the Base URL is the address of the GCEMS server. Verify this is correct or alerting will not work correctly
