IIRC, this is in a structure that exists entirely in memory. It's
checkpointed every 15m (by default) in xymond.chk in your tmpdir, so you
could retrieve it from there if you need to. You can also send xymond a
USR1 signal to force an immediate checkpoint.

I believe xymond will always use the most-recent TTL for a status report
as canon. To wit: "The last report I got said to expect something else
within XX minutes."
