This section introduces the Rendezvous messages published by the Tracker Server and describes their formats. Those messages fall into three categories: Job messages,
SYSLOG messages, and Alert messages.
You can receive all Job, SYSLOG, and Alert messages from the Tracker Server by using the Mainframe WebUI on a Web browser or from the TIBCO BusinessWorks sample project, both of which are shipped with the product.
At the end of each job step and at the end of the job it monitors, the Tracker Server publishes Rendezvous messages to the subject specified on the startup parameter
DEST-JOBSTEP=tibtrk.jobstep. Applications (servlets, programs, Mainframe WebUI, BusinessWorks projects, and others) that listen on this subject receive the Rendezvous messages.
Table 4 defines the content of those messages.
TIBCO Mainframe Service Tracker can select specific messages written to z/OS SYSLOG based on the message IDs or search strings. For each message it selects, the Tracker Server publishes the
SYSLOG message to the subject specified in the startup parameter
DEST-LOGMSG=tibtrk.logmsg.
Table 5 defines the
SYSLOG message fields.
Hawk is a scalable tool for monitoring and managing distributed systems. It employs distributed
agents that run on nodes throughout a network. Those agents autonomously monitor system and application parameters and can act according to their values.
Hawk communicates and inherits many of its benefits through TIBCO’s messaging software. Because Hawk is designed specifically for monitoring distributed systems, no centralized console exists. However, Hawk contains a console application,
TIBCO Hawk Display, as a user interface for viewing events on the network and for configuring agents. In addition, other TIBCO products with console and dashboard facilities are available.
Figure 3 illustrates the architecture.

Figure 4 shows the main Hawk components on a monitored system.
Rule – A user-defined monitoring construct. A rule contains three parts: the data source monitored by the agent, one or more tests that check for conditions, and one or more actions to perform if a test is true.
The TIBCO Hawk Display console subscribes to alert messages generated by TIBCO Hawk rule bases and presents them in an organized view. Color-coded alerts denote the severity of reported problems. In TIBCO Hawk Display, you view the status of mainframe tasks or jobs as reported by TIBCO Mainframe Service Tracker.
The main window of TIBCO Hawk Display graphically illustrates system behavior, with each monitored computer represented by a
container icon (see the left panel above). Through application menus and dialog boxes, you can create, modify, or distribute rulebases, which control the monitoring behavior of TIBCO Hawk agents.
TIBCO Hawk Display does not store centralized monitoring intelligence, but simply displays a view of events on your distributed systems. All TIBCO Hawk Display users view the same managed objects without complicated configuration schemes. You can also customize your instance of TIBCO Hawk Display without affecting other users and add more instances with no additional network overhead or configuration.
