On a 5-minute time interval, MRTG will start up, read the configuration file, and re-generate performance graphs.

Sending MRTG Graphs to a Web Server

MRTG builds all the graphs and web pages.

To browse and view the graphs produced by MRTG, make sure the web server is running. For information on how to set up a web server, go to http://www.apache.org/

To send MRTG graphs to a web server, follow these steps:

Step 1 Verify that the configuration file points to the correct working directory (WorkDir:) on your web server by entering the more command. See WorkDir: in the following example.

igloo:/opt/downloads/mrtg/mrtg-2.8.8/run ->moretravis-nas-01.cfgWorkDir: /export/home/www/mrtg/travis-nas-01/dial

#set defaults Options[_]: growright

#make legends reflect these are call counters YLegend[_]: Active Calls

ShortLegend[_]: calls

LegendI[_]:  calls:

LegendO[_]:  calls:

.

.

.

Step 2 To send the web pages and graphs to the web-server directory, enter the following command:

igloo:/opt/downloads/mrtg/mrtg-2.8.8/run ->./mrtgtravis-nas-01.cfg

igloo:/opt/downloads/mrtg/mrtg-2.8.8/run ->

Now, the crontab will automatically perform this function every five minutes.

Ignore any Rateup WARNING errors, which means that crontab is working in the background.
