Using Xymon 4.3.28 from the Terabithia RPMs.

I've been adding a few new client servers to our Xymon monitor. However, I have noticed today that for some graphs no graph title appears. The graph appears, the values appear (on the graph) and the graph lines appear. Just no title.

It seems that this affects those client servers which are configured in the hosts.cfg file with a NAME: entry. For example:

10.11.12.13 server1 # NAME:"server1 (pre-prod web)" testip !ftp ssh...

(I don't use FQDNs for the server names.)

It seems that entries we have added to the 'graphs.cfg' file, and where the TITLE uses the 'exec:' function have the problem. (See the 'graphs.cfg' man page for info about using 'exec:'.) So, for example we have in graphs.cfg:

======= [memory] TITLE exec:/bin/sh -c 'echo Memory Utilisation - $2' YAXIS % Used ...

Hello,

I finally got round to looking into this. I have attached a patch file against the 4.3.28 RPMs for the 'web/showgraph.c' file. The patch is only a few lines long, and seems to work okay. (All our graphs, those using 'exec:' for the title and those not, all appear with their correct titles.)

I have also added a patch for the 'web/graphs.cfg.5' man page. This now specifies that the RRD file parameters are double quoted, and if the hostname parameter also contains a space then that too will be double quoted.

As always feel free to change around the patches, or remove bits from them, as considered necessary :-)

John.
