MRTG is not supported on CentOS
The Multi Router Traffic Grapher (MRTG) is a tool to monitor various items in an IMG. Information such as temperature, CPU, memory, CPU usage and disk space is logged. The MRTG generates HTML pages containing PNG images which provide a live visual representation of data. MRTG log files are stored in the following directory:
/opt/dialogic/common/mrtg_logs (Software 10.5.1+)
/opt/cantata/common/mrtg_logs (Software 10.3.x-10.5.0)
The MRTG Data is refreshed in 5 minute intervals.
The following information is reported for different IMG components:
Traffic
CPU Utilization
Memory Data
Temperature Data
See IMG 1010 - Sample MRTG Main Page.
Using MRTG:
Perform the following steps to install and use the MRTG.
IMG 1010 - Setting Up An MRTG Web Host (optional)
To generate MRTG logs, press the MRTG Scripts button on the Dialogic® EMS pane in ClientView. You can update the MRTG from the IMG 1010 - Channel Groups pane after you add channel groups.
If you add a Channel Group in ClientView, you must re-generate the MRTG scripts to include those Channel Groups in the MRTG log files.
To view logs, connect to the Apache Web Server (from step 2), or go to either
/opt/dialogic/common/mrtg_logs (Software 10.5.1 +)
/opt/cantata/common/mrtg_logs/ (Software 10.5.0)
and view individual logs with a web browser.
When using Microsoft Internet Explorer® as a Web Browser, an issue with the browser could arise where the cache is not properly updated and any MRTG Data that was previously viewed could be propagated to the newly opened MRTG window. To fix this issue, follow steps below.
Open Microsoft Internet Explorer®
Select Tools > Internet Options
Click on the 'General' Tab.
Click on 'Settings' button under Browsing History section.
Click on 'Every time I visit the webpage'
Select OK

This file shows a single graph for each IMG that is configured in the GCEMS. The main graph for each IMG is the Total Traffic single day graph. Click on a graph to view additional graphs for that IMG. This will take you to the IMG Index graph for that IMG.
Level 1: Local Host
The following graphs are generated for the local host:
CPU Utilization
Disk Utilization
Memory Utilization
Memory Swap Usage
Swap Statistics
Level 2: Individual IMGs
There is one IMG Index graph for each IMG. This page contains four graphs, shown below with applicable sub-graphs:
