How to graph your modem utilization with ploticus
This install process describes how to generate a stair-step graph of you modem usage throughout the day, with the explicit goal of answering the question:
- Do I have enough modems?
It is a bit involved. However, one you are finished you will be able to generate graphs like these, which are viewable from any web-browser (even a Manager can use it!)
The basic approach is as follows:
- Direct your hylafax log to your web-server using syslog
- Use syslog-ng or logrotate to keep log files small (weekly works well for me)
- Install the perl script
modem_usage_from_syslog.plas a CGI program on your web-server
- View the results in a web-browser
