NAME

6       LogCentral - Central logging service for distributed applications
7

NAME

9       LogCentral - service using the publisher/subscriber model, where compo‐
10       nents publish tagged messages and tools get back appropriate messages .
11

SYNOPSYS

13          LogCentral [options] ...
14

DESCRIPTION

16       LogCentral gathers and publishes the messages to the subscribers.  Mes‐
17       sages are tagged, the LogCentral service only sends suscribers filtered
18       messages.
19
20       Before starting the LogCentral, you must:
21
22       · launch a CORBA Naming Service.
23
24       · launch log forwarders if needed
25
26       · launch LogCentral service
27
28       [Remark: LogCentral must be launched before the log tools/components]
29

OPTIONS

31       -config [name]
32              The configuration file for the LogCentral service.  First,  Log‐
33              Central  will  use  the file provided by command-line, then read
34              environment variable $LOGCENTRAL_CONFIG and in last  resort,  it
35              will look for a file named "config.cfg" in current directory.
36

CONFIGURATION FILE

38       You  can  pass  a  configuration  file to LogCentral using command line
39       options through the -config option. Configuration  file  lists  several
40       classes  of  tags describing the messages. A minimal configuration will
41       look like this:
42
43       [General]
44
45       [DynamicTagList] [StaticTagList] [UniqueTagList] [VolatileTagList]
46
47       The general tag accept the following parameters: *  'port=xxx',  speci‐
48       fies the port to use
49
50       · 'MinAge=xxx',  defines  the minimum period of time that messages will
51         be stored in the LogCentral
52
53       · 'DynamicStartSuffix=START', expands tags  with  START.  See  Dynamic‐
54         TagList.
55
56       · 'DynamicStopSuffix=STOP', expands tags with STOP. See DynamicTagList.
57
58       The  other  four  categories configure the state manager of the LogCen‐
59       tral. It is important to know that all tags will be expanded  with  two
60       suffixes to generate pairs of tags.
61
62       · VolatileTagList, should contain all the monitored tags. Not essential
63         but it may be requested by some tool.
64
65       · UniqueTagList, should contain tags that will overwrite  the  previous
66         messages of this tag
67

RATIONALE

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