Sar2html is a Web-based front end for performance monitoring. It converts sar binary data to graphical format. Both the command line and Web interface provide the same functionality. HPUX 11.11, 11.23, and 11.31, Redhat 3, 4, 5, and 6, Suse 8, 9, 10, and 11, and Solaris 5.9, 5.10. 5.11 are supported for performance monitoring. The reporting tool runs on Linux only. If you have customers facing performance problems on the operating systems listed above, you may send sar2ascii to collect performance data. Then you may plot performance graphics and generate performance reports in PDF format through sar2html. If you are a systems administrator, you may monitor your systems by accessing them through sar2html. Automatically collecting performance data in a predefined time window will be implemented soon.
