NAME

       LogCentral - Central logging service for distributed applications

NAME

       LogCentral - service using the publisher/subscriber model, where components publish tagged
       messages and tools get back appropriate messages .

SYNOPSYS

          LogCentral [options] ...

DESCRIPTION

       LogCentral gathers and publishes the messages to the subscribers.   Messages  are  tagged,
       the LogCentral service only sends suscribers filtered messages.

       Before starting the LogCentral, you must:

       • launch a CORBA Naming Service.

       • launch log forwarders if needed

       • launch LogCentral service

       [Remark: LogCentral must be launched before the log tools/components]

OPTIONS

       -config [name]
              The  configuration file for the LogCentral service.  First, LogCentral will use the
              file provided by command-line, then read  environment  variable  $LOGCENTRAL_CONFIG
              and  in  last  resort,  it  will  look  for  a  file  named "config.cfg" in current
              directory.

CONFIGURATION FILE

       You can pass a configuration file to LogCentral using command  line  options  through  the
       -config  option. Configuration file lists several classes of tags describing the messages.
       A minimal configuration will look like this:

       [General]

       [DynamicTagList] [StaticTagList] [UniqueTagList] [VolatileTagList]

       The general tag accept the following parameters: * 'port=xxx', specifies the port to use

       • 'MinAge=xxx', defines the minimum period of time that messages will  be  stored  in  the
         LogCentral

       • 'DynamicStartSuffix=START', expands tags with START. See DynamicTagList.

       • 'DynamicStopSuffix=STOP', expands tags with STOP. See DynamicTagList.

       The  other  four categories configure the state manager of the LogCentral. It is important
       to know that all tags will be expanded with two suffixes to generate pairs of tags.

       • VolatileTagList, should contain all the monitored tags. Not  essential  but  it  may  be
         requested by some tool.

       • UniqueTagList, should contain tags that will overwrite the previous messages of this tag

EXAMPLE

       • Launching the LogCentral

          LogCentral -config ./LogCentral.cfg

RATIONALE

       The  LogCentral  uses  CORBA  as its communication layer. While it's a flexible and robust
       middleware, its deployement on heterogeneous networks still is delicate  and  may  require
       using ssh tunnels.
