SirMon is a comprehensive facility for monitoring the performance and availability of Model 204 Online systems that is completely integrated within the Mode 204 environment.

SirMon is part of the RKTools family of products from Rocket Software. As of Model 204 V7.5, the functions and facilities necessary to run RKTools are built into the Model 204 kernel. Earlier versions of SirMon require the installation of the Sirius Mods, with a version equal to or higher than the SirMon version.

SirMon overview

SirMon combines the real time monitoring of Model 204 performance with intelligent full screen (TN3270 or browser) displays that facilitate System Manager duties. Displays may be scrolled and sorted by displayed statistics and parameters. SirMon also supports an automatic refresh mode for timed, "hands-off" operations.

These features are designed to highlight significant resource consumers. Other features, such as the ability to restrict displays of users and subsystems to those holding a particular file open or preventing checkpoints, are designed to identify and solve problems with enqueuing and data availability.

Users may be bumped or have their priority reset from within SirMon, and subsystems may be stopped and started. SirMon is completely integrated with the Model 204 security scheme, so users have access to commands in SirMon only if they have access to them at Model 204 command level.

SirMon also provides a background monitor which measures an array of system statistics against user-defined thresholds, sending warnings when problems are detected.

SirMon divides the Model 204 Online into System, Subsystem, File, User, and Task statistics. In addition to those statistics collected by Model 204, SirMon provides an extensive collection of additional statistics and information that is invaluable for understanding the performance of a Model 204 Online. Online Help facilities explain the meaning of all statistics available for display.

SirMon is distributed with a set of pre-defined screens or browser pages for each display category. The information displayed ranges from general overviews to highly specific and targeted views of particular users, files, or other aspects of the Model 204 system. Online Help information is automatically tailored to the data displayed on the current screen. An integrated "fastpath" command structure or browser menu allows fast navigation between the various display screens.

SirMon provides a collection of pre-defined monitoring options known to be useful for analyzing Model 204 performance and solving performance problems. Extensive customization facilities make it easy to design and implement screens or views that track information of interest to your particular site. These locally-defined custom displays are fully integrated within SirMon, including in one or both of the user interfaces (TN3270 or RKWeb): support for display sorting, the standard prefix command set, fastpath access, and automatically generated Help text.
