One thing I noticed very recently which might be worth considering for 4.3.29:
xymond/etcfiles/xymonserver.cfg.DIST contains:
NTPDATEOPTS="-u -q -p 1"
If on the host running xymond, ntpdate from the ntpsec project is installed, then I just get the warning:
$ ntpdate -u -q -p 1 127.0.0.1 ntpdate: -p is no longer supported. 2019-04-11 19:22:28.524619 (-0200) +0.000002 +/- 0.000053 127.0.0.1 s4 no-leap $
So it might be an idea to drop the "-p 1" completely.
That seems premature. The fact that ntpseq has dropped the parameter does not make it common or standard.
Dropping the "-p 1" option means ntpdate will attempt to collect more than one time sample before returning. In all man pages I've consulted the default value for "samples" is 4. Which means that each non-answering server will block that xymonnet queue for three additional seconds.
If you're using ntpsec, I don't think it is unreasonable to expect you to tweak that parameter on your own server. I don't think it is reasonable to build in a 4x longer delay for everyone.
