Use Health Monitor to view a snapshot of the
overall system health of your business solution. This widget provides a single
place from which you can quickly assess the status of application servers,
nodes, clusters, deployment environments, messaging engines and their queues,
databases, system applications, and failed events.
The
Health Monitor widget displays the status of and
information about the following items on your system, organized into tabs
for easy browsing.
- Topology tab
- Deployment environments
- Lists the status of all deployment environments on the system that match
any filter criteria you specified. If you specify no criteria, all objects
are displayed.
- Clusters
- Lists the status of all clusters on the system that match any filter criteria
you specified. If you specify no criteria, all objects are displayed.
- Standalone servers
- Lists the status of all standalone servers on the system that match any
filter criteria you specified. If you specify no criteria, all objects are
displayed.
- Node agents
- Lists the status of all node agents on the system.
- System Applications tab
- System applications
- Lists the status of Business Process Choreographer, Common Event Infrastructure
(CEI) and Service Component Architecture (SCA) applications and services configured
on your system (for example, the failed event manager, Business Process Choreographer
containers, and the Event Service), as well as Business Space widgets and
the Business Space Manager.
- System data sources
- Lists the data sources that match any filter criteria you specified. If
you specify no criteria, the Health Monitor displays all data sources on the
system, including the Common database, the Business Process Execution database,
the Common Event Infrastructure database, and the Service Integration Bus
database.
- System messaging engines
- Lists the messaging engines configured on the system and application buses
(SCA.SYSTEM.busID.Bus, SCA.APPLICATION.busID.Bus,
CommonEventInfrastructure_Bus, and BPC.cellName.Bus).
- Applications tab
- Applications
- Lists enterprise applications installed on the system that match any filter
criteria you specified. If you specify no criteria, all objects are displayed.
- Failed event count
- If the Recovery subsystem is enabled, lists the number of failed events.
- Queues tab
- Queue depth
- Displays current queue depth for the messaging point. If not all messaging
engines are running, only partial queue depth is available. Use the radio
buttons to select the subset of queues you want to display in the Health Monitor.
Status can be running, stopped, or unavailable.

Using Health Monitor
In Health Monitor, you can perform the following actions:
- Customize the widget to provide status on a desired subset of system components.
Click Configure from the widget menu to access the
list of item types available in Health Monitor. By default, all item types
are selected; clear any that you do not want to monitor. You can update this
configuration at any time to change the types of system components you are
currently monitoring.
In addition, you can use the text boxes under certain
system components (clusters, servers, deployment environments, applications,
and system databases) to further filter the monitoring results. Enter the
full text or use partial text with a wild card character. The text fields
support two types of wild cards: the question mark (?)
is a single-character wild card and the asterisk (*)
is a multi-character wild card. You can enter multiple values delimited by
a comma (,) or a carriage return.
- Specify the rate at which the widget refreshes the information. You can
specify any positive value in the Refresh every numberOfSeconds seconds field;
set it to 0 (zero) to prevent Health Monitor from refreshing.
- Specify the number of rows to show per page. For each system component
you are monitoring, Health Monitor displays only the number of rows you specify.
All other rows are placed into tabbed pages; use the forward arrow (>)
and back arrow (<) to navigate through the data.
When you have configured Health Monitor to display status for a large number
of system component types, use a smaller value for the Rows per
page field to prevent the need for excessive scrolling.
- Specify the maximin number of query results sent from the server to the
client. You can specify any positive value in the Maximum query
result field.
Tip: If you are displaying status for all system component
types, note that setting a frequent refresh rate can affect performance.
