By default, xymond only creates a snapshot (specifically: sends a copy of
the current client report for a $HOST over the 'clichg' channel to the
xymond_hostdata listener) when an ALERT threshold is crossed.


I'd considered a patch that would cause xymond to send a "spurious" clichg
message on a regular basis while something is in an alert state
persistently (eg, every half-hour snapshots), but this is really something
that would have to be highly configurable for different installations...

A hack that can be done now is to create an otherwise-ignored status test
for all hosts (eg, "tied"). On whatever frequency you want, send a "red"
status in for the host on this test, followed by a green or clear status.
This will cause xymond to save a snapshot in which should be visible from
either the 'tied' service history dot, and/or an event log report for the
host generally.
