How to debug showgraph.sh?
Hello,
I'm sure I saw a way to run showgraph.sh from the command-line in order to debug problems with it. As far as I remember it required setting the variable QUERY and perhaps some others before running it. I have looked, but cannot find how this was done.
Can anyone offer any help here?
(I have 4 client status pages for a local test which are not showing a graph, but are showing a link where the graph should be. The corresponding 'trends' page shows the graphs (so obviously RRD is working okay, and the graphs do exist). Also I have one client which does show the graph on the status page. So I want to see why one works and four fail.)
Thanks,
John.

If you have a graph link in your browser like
http://www.xymon.com/xymon-cgi/showgraph.sh?host=jorn.hswn.dk&service=la&gra...
(taken from the "cpu" graph on the www.xymon.com site), then you can run it "by hand" with:
REQUEST_METHOD=GET SCRIPT_NAME=showgraph.sh QUERY_STRING="host=jorn.hswn.dk&service=la&graph_width=864&graph_height=180&disp=jorn.hswn.dk&nostale&color=green&graph_start=1343160394&graph_end=1343419594&graph=hourly&action=view" (i.e. everything after the "?" in the URL)
export REQUEST_METHOD SCRIPT_NAME QUERY_STRING
xymoncmd showgraph.cgi

You could also insert this into showgraph.sh
env > /tmp/showgraph.outto save the query string and other things. Add in the export & xymoncmd lines and you have a script to fiddle with.

Hello,
Thanks for that. It was just what I wanted.
Turns out that the error I'm getting is 'No DS called 'in' in 'ifstat.eth0.rrd'. However, my test is called 'if', not 'ifstat'.
It seems that the entry I had in graphs.cfg was 'FNPATTERN ^if.(.+).rrd' (which would match the previous 'ifstat' entry). Changing my pattern to '^if\.' sorted out the problem :-)
Now I have to work out why the one graph for one client I did have for the 'if' test appeared - it seems that the client has no 'Network traffic' graphs at all (or RRD files) so something with the netstat or ifconfig data must be causing a problem. (Both do exist in the client data.)
John.
