IMG 1010 - Overview of MRTG

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.
