HP GLANCE/XL by Paul Primmer, Application Support Division HP GLANCE is an interactive, real-time performance monitoring software tool for HP 3000 systems. HP GLANCE/XL provides online examination of MPE XL system activity, while HP GLANCE/V provides similar functionality for MPE V/E systems. Both software tools allow you, the System Manager, to gain a "quick look" at system performance. Simple, quick, and easy-to-access information regarding system performance and resource utilization enables you to identify and resolve potential performance problems promptly. HP GLANCE provides immediate data upon which to make resource management decisions. When you need to know what is happening on your system right now, HP GLANCE can mean the difference between guesswork and factual information. HP GLANCE can be used to greatly facilitate day-to-day management of your system by providing online diagnostic performance data. In essence, HP`GLANCE enables you to check your system's activity quickly and easily so that you can more effectively evaluate system performance activity. HP GLANCE is a host-based interactive tool. It requires an HP terminal which is supported on the HP`3000 system being monitored. Supported terminals include: HP262X family, HP239X family, HP 150 personal computer, HP Vectra personal computer (running terminal emulation software), and the HP 700/9X family. HP GLANCE will utilize the features of a color CRT if present, although a color CRT is not required. Clarify an Abundance of Data HP GLANCE software displays three levels (Global, Job/Session, and Process) of performance data to help you quickly and easily identify system performance activity. Global Level The GLOBAL level screen lets you see the overall system activity. Resource consumption bars at the top of this screen represent the global utilization of the three primary resources of the system: CPU, DISC, and MEMORY. Below these bars "interesting" processes are brought to your attention. A process is considered interesting when it exceeds any one of the following user configurable conditions. * It is newly created. * It is terminating. * It is utilizing too much of a system resource (CPU or DISC). * It is executing too many terminal transactions. * It is receiving poor terminal response time. Job/Session Level The JOB/SESSION screen allows you to examine a specific JOB or SESSION. The three primary global bars remain at the top of the screen so you can compare your JOB or SESSION in relation to the entire system. Following the system wide resource bars, CPU and DISC resource bars track the selected JOB or SESSION. Below the JOB/SESSION resource bars, detailed information about processes running within the selected JOB or SESSION are shown. Process Level The PROCESS level screen allows you to closely examine response time and disc I/Os. A STATE bar lets you see the components of response time, and file information lets you see where your disc I/Os are going. Simplify Performance Diagnosis The HP GLANCE simple design allows novices total system view without any complexity, yet it provides seasoned professionals the critical information they need. Online help facilities can assist you to understand quickly how to use the tool and the data presented. Hard copy output is provided with the HP GLANCE Print Facility. To make things even easier, most commands can be executed with a single keystroke.
