I am running three different Hobbit servers at three different
sites and all work great except one.
On the one not running great, I see everything fine except that
all graphs are missing titles and lables along grid lines. Other
than this missing text on the graphs, the graphs show the data fine.
For the life of me I cannot figure out the difference between this
misbehaving installation of Hobbit and the other two that are
working great. Could anyone offer any hints as to where to look?
If it's only text missing, you might want to check that the server has
the same fonts installed as on the other two servers.
You could also try manually generating the graphs and see if rrdtool
complains about anything. For example, I have Hobbit on a Gentoo
server called lorien, so I can generate the cpu load graph manually
like this:
rrdtool graph /var/www/localhost/htdocs/la.png \
"DEF:avg=/home/hobbit/data/rrd/lorien/la.rrd:la:AVERAGE" \
"CDEF:la=avg,100,/" \
"AREA:la#00CC00:CPU Load Average"
rrdtool responds with "481x168" which is the pixel size of the
image generated. I can then load that image in a browser at
http://localhost/la.png. The DEF, CDEF & AREA lines come from the
server/etc/hobbitgraph.cfg file.
