a xymon 4.3.27 installation I set up a while back generally works, but
comes up with all blank graphs.
Digging into it some more, I have
#!/bin/sh
rrd="/var/xymon/rrd/Gurgler/tcp.ssh.rrd"
rrdtool graph "/tmp/rrd-ssh-output.png" \
--width=800 -v "ssh response time" \
-s 'now-48h' -e now \
DEF:time1=${rrd}:sec:AVERAGE \
LINE2:time1#FF0000:time1
creating a proper graph (for the fun of it: <https://www2.nt.tu-darmstadt.de/~hf/xymon/rrdtool-graph-output.png>;).
On the other hand,
#!/bin/sh
REQUEST_METHOD=GET
SCRIPT_NAME=showgraph.sh
QUERY_STRING="host=Gurgler&color=green&service=tcp%3aconn&graph_height=120&graph_width=576&disp=Gurgler&nostale&graph=daily&action=view"
export REQUEST_METHOD SCRIPT_NAME QUERY_STRING
showgraph.cgi \
--env=/etc/pkg/xymon/xymonserver.cfg \
| tail -n +4 > /tmp/showgraph-output.png
leaves me with an empty graph - see <https://www2.nt.tu-darmstadt.de/~hf/xymon/showgraph-output.png>;.
Adding --debug doesn't bring up anything helpful; --save does not write anything, fwiw.
For sh!ts and giggles, and to rule out pkgsrc artefacts, I installed xymon from the distribution sources, and got identical results..This needed a few NetBSD specific patches, which I saw the pkg maintainer had sent to the list before, but they were never incorporated -- what is the accepted way to submit patches?
I do not at this point have a comprehensive mental image of xymon's inner workings, so hints and pointers would be very helpful.
Cheerio,
hauke
