.SH DESCRIPTION
The

parameter reports how many seconds a specific client took to reconnect to
each target during the most recent recovery window.
The timer is reset when recovery starts and completes when each export first
connects to the target.
This is useful for isolating a specific client's recovery delay,
which is otherwise shown only in aggregate form in the full
.BR mdt.recovery_reconnect_histogram (4)
or in limited numbers in
.BR mdt.recovery_reconnect_top (4).
