0018 The CMS MessageLogger Service is meant to allow code in modules, other
0019 services, and other framework "scaffolding" to log
0020 messages to a unified message logging
0021 and statistics facility.
0022 <p>
0023 The MessageLogger Service captures and coordinates messages originating in
0024 multiple modules (which, under the CMS framework, will in general be running
0025 in multiple threads) into a specified set of destinations.
0026 The management of these destinations is
0027 based on the ZOOM Error Logger package developed at Fermilab.
0028 <p>
0029 All users of the MessageLogger service should read the section on
0030 <a href="MessageLogger.html#howSend"> Issuing Messages </a>.
0031 <p>
0032 The behavior of the MessageLogger can be adjusted via lines in the
0033 job's configuration file (.cfg).
0034 Users wishing to customize the behavior of the MessageLogger should read
0035 the section on
0036 <a href="parameters.html"> MessageLogger Parameters </a>.
