Before you begin using System Monitor, you must have the required web servers, client browsers, and other software installed on your system.
You also must decide whether you want to use the default monitors provided with System Monitor or if you want to create additional monitors using the Monitor Definition wizard. For example, you might want a monitor called System Overview, which displays status and start time of all system components. You create this monitor using the Monitor Definition Wizard, a tool opened from System Manager.
System Monitor requires the following software, listed in Table 1:
Table 1. Required software for System Monitor
Supported Web servers | Software required on Web server | Supported browsers |
---|---|---|
A Web application server which supports JSP versions 1.1 or later,
and servlets versions 2.2 or later, such as IBM WebSphere Application
Server Express versions 5.0.2 or 5.1, IBM WebSphere
Application Server versions 5.0.2 or 5.1, or Tomcat
versions 4.1.24 or 4.1.27 (using IBM JDK
1.3.1)
|
DB2 Client (if using DB2 for repository database)
|
|
Perform the following step to gain a better understanding of what information is included in each monitor:
Default monitor | Definition | Display options | Available operations when viewing monitor |
---|---|---|---|
System Overview | Overview of the current status of all major components of the system: collaborations, connectors, maps, and relationships | Table tree (a table with expandable nodes in the first column that display more rows) |
|
Collaboration Statistics | Current status and statistics of all collaborations in the system:
| Table |
|
Connector Statistics | Current status and statistics of all connectors:
| Table |
|
Map Status | Status of all maps | Table | Start and stop |
Relationship Status | Status of all relationships | Table | Start and stop |
Server Statistics | Current statistics of the server: the number of failed and successful calls, events, and flows | Stacked bar | None |
Database Connections | Current status of database connections:
| Table | None |
Message Queues | Current status of message queues:
| Table | None |
Business Objects | Current statistics of the business objects for a particular connector: business objects sent and business objects received | Table | None |
Connector Subscriptions | Current statistics of the subscriptions for a particular connector:
| Table | None |
Collaboration Events | Current statistics of collaboration events, which includes the following
information:
| Bar | None |
Historical Server Statistics | Server statistics for a specific period of time. Statistical
information:
Time intervals:
| Bar | None |
Historical Server Flows | Flow statistics of the server for a specific period of time at certain
time intervals. Statistical information:
Time intervals:
|
| None |
Historical Collaboration Flows Stack | Flow statistics of a particular collaboration for a specific period of
time at certain time intervals. Statistics information:
Time intervals:
| Stacked bar | None |
Historical Collaboration Flows Line | Flow statistics of a particular collaboration for a specific period of
time at certain time intervals. Statistics information:
Time intervals:
| Line | None |
Event Rate | Current number of processed events per minute | Meter | None |
Flow Control | Current state of collaboration objects and connectors under Flow
Control:
| Table | None |
State Change Log | Current persisted state changes on a component for a specified time
period. State change information:
Time intervals:

Before you begin: Review the existing default monitors in Table 2, to see if the monitor you want to create already exists.
Perform the following steps to create a monitor:
Figure 1. Monitor Definition Wizard, page for selecting information type and display option
Each information type has one or more available display options, and each display option has configurable properties. When you select an information type, only the display options for that information type are available under Displayed Option(s). For a description of the configurable properties of each display option, see Steps for using monitor display options, and for examples of how the display options appear in System Monitor, see Examples of display options.
Figure 2. Monitor Definition Wizard, Specify Monitor Properties page
Figure 3. Monitor Definition Wizard, Specify Attribute Thresholds screen
Perform this step to use display options for monitors you are creating with the Monitor Definition Wizard (see Steps for creating additional monitors) or using monitors in System Monitor (see Steps for setting display properties:
Refer to Table 3 to determine ways you can configure display options when
creating monitors in Monitor Definition Wizard, or when you are using the
monitors in System Monitor. (For examples of the display options, see Examples of display options.)
Table 3. Configurable display options for monitors
Display option | Properties you can configure when building monitors in Monitor Definition Wizard | Properties you can configure when using monitors in System Monitor |
---|---|---|
|
|
|
| None |
|
Meter | Meter threshold | Font and color settings of the labels and data |
The following exemplify the display options you can select when creating monitors in the Monitor Definition Wizard and how they appear in System Monitor:
