Once you’ve generated some graphs, you will want to look at them to see the results. To make it easier to view the graphs, MRTG comes with an indexmaker script that generates HTML index pages. Here’s how to run indexmaker for a typical set of graphs:
indexmaker --title "Cisco to Internet" \
--filter name=~'cisco' --output /mrtg/images/cisco.html /mrtg/run/mrtg.cfg
This command creates one index page with the five-minute average
graph for each target you’ve specified in your
mrtg.cfg file. Keep in mind that the target is
the interface from which you’re gathering data. If you have
four targets for your router, there will be four graphs in the index
file, all pointing to the daily, weekly, monthly, and yearly summary
graphs for that target. The - -title option tells
indexmaker what title to use for the index file.
- -filter name=~cisco allows you to select some of
the targets in the
mrtg.cfg file by using a
regular expression: we told indexmaker to find all
targets that include the string
- -output option is the name of the index file.
The final argument on the command line is the full path to the
configuration file. Table 13-1 gives a synopsis of
these options as well as some other useful options to
