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.
