The purpose of this small program is to generate html pages on the fly from MRTG rrd files.
html and images are built in realtime, this mean no .html or .png file
stored on server.
For a fast display with many small image, the html
include inline png data.
This program is a rainy saturday project, but it may be useful to some people so i decide to publish it as a beerware.
- "THE BEER-WARE LICENSE"
- jc@michot.fr write this file. As long as you retain this notice
- you can do whatever you want with this stuff.
- If we meet some day, and you think this stuff is worth it,
- you can buy me a beer in return.
You only need to configure below the $mrtgconfigfiles with one or several absolute path and filename for your mrtg configuration file. (theses files must be readable by your web user running php script)
Syntax example:
[url]/mrtgrg.php
[url]/mrtgrg.php?cfg=mrtg.cfg&target=port24
[url]/mrtgrg.php?cfg=mrtg.cfg&target=port24&png=weekly
To manualy force width &| height (this can also be configured inside mrtg config file):
[url]/mrtgrg.php?cfg=homebridge.cfg&target=power-home&png=weekly&width=1400&height=300
To manualy force 2waygraph:
[url]/mrtgrg.php?cfg=homebridge.cfg&target=power-home&png=weekly&width=1280&height=450&force2way=1
A new option is available in your MRTG config file:
Rrd*Graph[ TARGET ]: 2waygraph,forcearea,forceday
forceline: force display line/s
forcearea: force display area/s
forceday: do not use week number in month graph
2waygraph: graph in/ou in 2 way (up/down a 0 line) (enable forcearea)
autoscale: man rrdgraph
autoscale-max: man rrdgraph
autoscale-min: man rrdgraph
All test has been done with: FreeBSD and pkg mod_php74-7.4.27 php74-gd-7.4.23 php74-pecl-rrd-2.0.1_1
