[Xymon] [PATCH] Config option for updated time comment in graphs

[John Horne]

Hello,

We are using the Terabithia 4.3.30 RPMs.

It is hard-coded that Xymon will add a comment to graphs to indicate when the
graph was last updated. It is seen at the bottom of the graph legend as (for
example): Updated: 13-Sep-2019 17:14:00

This is something we do not want. (The graph itself will soon show if it is not
being updated, and we have other monitoring in place to indicate if any
services/processes have stopped.)

Attached is a patch that adds a 'xymonserver.cfg' configuration file
environment variable to indicate if the above comment should be added to graphs
or not. By default it is set to true. It seems better, for us at least, to use
a config option rather than having the graph comment hard-coded.

The patch itself is just a couple of lines in showgraph.c, and a default value
set in the environ.c file. The other (3) patches are again just one or two
lines each updating the documentation files for the new variable.

The patch has been tested by us, and works fine. Because of the location of the
new call to xgetenv within the showgraph.c file, it means that any change to
the config file for this variable takes immediate effect. No service restart
required.

Feel free to modify the patches as you wish, or to ignore them if it is not
felt to be useful at all.



John.
