If it helps any, my graphs are being generated with the same links as
yours (nostale vs no nostales) without issue.

There's probably some other underlying issue.

Hi,

I got different issue with graphs, but I think my problem should be
related to your comment :

It's worth checking hobbitgraph.cfg if you have added a number of your
own custom graphs.
The FNPATTERN operator is doing a regexp match, but in some cases the
default pattern definition is very loose.

For example, I'd added a bunch of devmon based system health check
reporting stuff which generated file names like
/var/lib/hobbit/rrd/HOSTNAME/temp.memory11.rrd
These were causing the memory graph to die because it was attempting to
query non-conformant RRDs for the particular graph. Solved by tightening
the regexp definition as below (adding ^ in front, which means the
filename has to start with memory, not just have it as a substring).

[memory]
        FNPATTERN ^memory.(.+).rrd
        TITLE Memory Utilization

Note that the FNPATTERN is not used when deciding if there are any RRD
files to use to display a graph at all on the test status page. It just
seems to glob TEST*.rrd to count the number of files to decide how many
lines to display on the graph for TEST. This is with 4.2.3.

David.

Thank you for your advices. I migrated my xymon server (and some
clients)
to 4.3.0-0.beta2, without migrating (is it needed anyway ?) my rrd
files.
My issue is very simple (and strange), I've 7 partitions monitored by
xymon, all are reported correctly. I've 2 graphs for 3 partitions, but
there should be a 3rd one for the 7th partition. Instead, I've a broken
link.
I've the same issue on custom tests/graphs. Many datas are graphed, but
some graphs are missing. I think there should have a way to deal with
it,
in modifying how many values are on the same graph, or in correcting the
root cause. Actually I don't have any skill in C nor php, so I can't
solve
it myself.
Do you think this behaviour is related to your advice (changing
FNPATTERN)
?

Regards,
Damien
