Monitoring
==========

Send buffers
------------

The :cpp:func:`get_available_send_buffers<FelixClientThreadExtension520::get_available_send_buffers>`
function can be used to check the number of available send buffers per FID for which
:cpp:func:`init_send_data<FelixClientThreadExtension520::init_send_data>` was called. Note, that
this function returns the minimum number of available send buffers since the last call to this
function and not the current number of available send buffers.

.. tip::
  Many FIDs might share the same connection (and therefore buffers) and will report the same number
  of available send buffers.

.. caution::
  The number of receive buffers cannot be monitored.


Block decoding
--------------

In case felix-star is sending entire blocks and not decoded messages, statistics about the block
decoder (such as the number of blocks received, the number of blocks decoded, and the number of
blocks dropped) can be obtained using the
:cpp:func:`get_block_decoder_stats<FelixClientThreadExtension520::get_block_decoder_stats>`
function. This function returns a structure containing the statistics per FID.
