Overview of Monitoring Functions

The monitoring functions of TIBCO SmartSockets IPC, which is built into RTserver and RTclient, offers many features, including:

A number of standard monitoring message types provide access to hundreds of pieces of IPC information about the application.

In addition to IPC information, other information can be obtained about processes such as their memory usage, CPU usage, and what node they are running on.

Most types of information can be either polled once to provide a one-time snapshot, or watched to provide continuous updates when changes occur.

Information is available about both RTclients and RTservers.

RTmon is a standard RTclient for monitoring that provides both a Graphical Development Interface (GDI) and a Command Interface (CI).

When polling or watching information, individual items or all items of a certain type can be easily accessed.

All monitoring of a TIBCO SmartSockets application goes through RTserver. Typically, a request for particular information is sent to RTserver, then RTserver retrieves the information and sends it back to the requesting program. To initiate a monitoring request in your program, call one of the functions in the TipcMon* API. This sends a message of type MON_*_SET_WATCH or MON_*_POLL_CALL to RTserver. The information is returned to the program by RTserver with a MON_*_STATUS or MON_*_POLL_RESULT message. When the information returns, an RTserver message process callback (TipcSrvProcessCbCreate) or RTserver message default callback (TipcSrvDefaultCbCreate) should be used to process the message.

This lesson shows you how to use just a small part of the extensive monitoring and locating services of TIBCO SmartSockets. Details on the monitoring and locating services available in TIBCO SmartSockets can be found in the Chapter 5, Project Monitoring, in the TIBCO SmartSockets User’s Guide. Man pages for the TipcMon* API can be found in the TIBCO SmartSockets Application Programming Interface reference.
