PLAISTOW, NH (May 9, 2002) Aptitune Corporation has announced the general release of SarCheck Version 5.0 for Solaris SPARC and HP-UX. SarCheck is a performance management tool designed to assist system administrators in the analysis of system performance by translating the output of several monitoring utilities into a plain English or HTML-formatted report. SarCheck identifies performance bottlenecks, finds runaway processes and memory leaks, recommends changes to various tunable parameters and hardware configurations, and quantifies remaining system capacity.
The most important new feature in SarCheck Version 5.0 is its graphing capabilities. SarCheck now uses gnuplot to create graphs on the fly and inserts them into its HTML output. Both PNG and JPEG graphs are supported and the graphs highlight information specific to the operating system and the values of various kernel parameters.
SarCheck is designed to help systems administrators learn more about how their systems work by explaining resource utilization and capacity limits in plain English. It uses tools available within the operating system, primarily sar and ps, to learn how the system's resources are being utilized. It then makes recommendations for kernel tuning and hardware upgrades, based on the system's resource utilization. SarCheck also helps the administrator to diagnose problems remotely, and to quickly recommend or implement corrective actions. Because SarCheck has been specifically designed with safety in mind, it will make detailed recommendations instead of attempting to fix problems itself. It will also explain the reasons for its recommendations.
SarCheck runs on many popular UNIX platforms, and support for other languages is planned. Contact Aptitune Corporation, P.O. Box 1033, Plaistow, NH 03865. Tel.: (603) 382-4200; Fax: (603) 382-4247. More information and examples of reports are available at http://www.sarcheck.com/.
