Monitoring system performance
Monitoring system performance is an integral part of administering any set of servers, whether they be production, test, or development oriented. Representing this performance data visually on a graph significantly aids the human eye in recognizing anomalies and trends. An accurate visual portrayal of past and present performance data allows the administrator to quickly pinpoint recurring bottlenecks and spot applications that could benefit from tuning. Using the utility Orca in conjunction with RRDtool, the SE Toolkit, and a web server such as Apache is an effective way to track such performance data on machines running the Solaris Operating System. Orca can also plot a variety of data collected from machines using other operating systems, enabling the administrator to create a centralized performance monitoring infrastructure.
