The question arises:
How to make RRDTool generate graphics in Mac OS X?
I installed rrdtool using homebrew on Mac OS x 10.6.8.
I can create a database, update some data and get data, but I can not create graphs for it.
Looks like a problem with glib and pango .
Both libraries are installed with homebrew .
I use:
- RRDTool 1.4.7
- Glib 2.34.2
- Pango 1.30.1
When I ran this:
rrdtool create datafile.rrd DS:packets:ABSOLUTE:900:0:10000000 RRA:AVERAGE:0.5:1:9600 RRA:AVERAGE:0.5:4:9600 RRA:AVERAGE:0.5:24:6000 rrdtool update datafile.rrd N:12322 rrdtool graph graph.png DEF:pkt=datafile.rrd:packets:AVERAGE LINE1:pkt#ff0000:Packets
I get:
