To use the message center, you must configure
your catalog servers as messaging hubs.
Procedure
Activate the catalog server as a hub for the health monitoring
framework. All catalog servers are activated as hubs by
default. You can enable or disable this setting with the following
property in the server.properties file for the
catalog server:
enableManagementConcentrator
Specifies if the catalog server is a hub for the message center.
This property is enabled by default. To disable the hub, set the value
to false.
Default:true
Optional: If you want INFO log messages to
be included, you must specify a regular expression that filters the
INFO log messages. Specify your regular expression with
the following property in the server.properties file
for the catalog server:
logNotificationFilter
Specifies a regular expression that filters all messages, including
the INFO level log messages. This filter determines which messages
generate health monitoring events. If you do not specify a regular
expression, INFO level log messages are not published through the
health monitoring framework. By default, only WARNING and SEVERE level
messages generate health monitoring events.
After your catalog servers are activated as hubs for the
health monitoring framework, you can use the message center in the
web console or the xscmd utility to view notifications
for health events.
