Troy,

At the moment, no. trace's of any type can only be configured to be
automatically performed on a ping/conn test failure. (Using the --trace
option to xymonnet and/or the 'trace' option in hosts.cfg.)


Unfortunately, adding it in at the time of the initial status result
doesn't scale very well (for any trace at all), since xymonnet can't send
its reports in until the trace completes.

It would be nice to be able to complete this afterwards (either as a
built-in feature, or via a custom script) and be able to add that into an
existing status message in a way that causes another snapshot to be taken,
but the current model doesn't really support that.

One possible integration point would be a modify message, however they can
only easily be on a single line, and one re-iterating the 'red' color
status, while it'll be displayed, won't cause a new snapshot to be taken
recording the trace itself for posterity.

If the record of the trace after the situation is resolved isn't important
to keep, that might be an option.


HTH,
