:Name: idleTimeout
:Scope: input
:Type: nonnegative integer
:Default: input=60
:Required?: no
:Introduced: 8.2608.0

Description
-----------
Set the maximum number of seconds that a client session may remain connected
without receiving any new bytes. When the timeout expires, ``imbeats`` closes
the session and does not acknowledge any incomplete batch. The value ``0``
disables the idle timeout.

This progress-based timeout applies even when the session has not started a
Lumberjack frame. It pauses while a complete, validated batch is submitted to
rsyslog and resumes when ``imbeats`` prepares the acknowledgement, so slow
local processing cannot turn a successfully submitted batch into an
unacknowledged retransmission. The resumed interval also bounds a client that
stops reading its acknowledgement. Use :ref:`param-imbeats-frametimeout` to
place an absolute deadline on a partially received frame.
