I think merging some add-ons into the Xymon source code should be
considered where those add-ons would be widely used, subject to licensing
restrictions.
For example, and I have not yet tested this add-on, but a way to alert on
processes using too much memory looks increasingly useful to me (together
with graphing of memory for certain processes):

Ideally the shell code that add-on uses would be converted to support in
the C code so that this could be configured in analysis.cfg rather than
hosts.cfg though.
Another example is Xymondash:
https://github.com/daduke/Xymondash
I haven't used it yet either, but it sounds good. Having said that,
development on that shouldn't be stymied by locking it to Xymon releases -
and it requires Python >= 3.5 (or 3.4). Maybe as a post-installation task
Xymon could ask if you wish to install it, check dependencies, ask a few
questions, download and install it?
It would be good to be able to present a more modern GUI as part of Xymon.
Kind regards,
