Detailed Description

MessageSvc used by the HLT applications.

This MessageSvc implementation it used by the HLT applications. It has some additional features compared to the default Gaudi MessageSvc. Most notably the forwarding of messages to the TDAQ ERS message system.

The message suppression is configured with the following parameters:

Parameters

<level>Limit	= 0: no message suppression for <level>
<level>Limit	= N > 0: suppress messages after N messages (per source)
<level>Limit	= -N < 0: use logarithmic suppression after N messages (per message)

Note, that the logarithmic suppression works on a per-message basis (ignoring any digits in the message).
