Oracle OSWatcher Black Box (OSWbb) : collects and archives operating system and network metrics that you can use to diagnose performance issues. OSWbb operates as a set of background processes on the server and gathers data on a regular basis, invoking such Unix utilities as vmstat, netstat, iostat, and top. From release v4.0.0, you can use the OSWbba analyzer to provide information on system slowdowns, system hangs and other performance problems, and also to graph data collected from iostat, netstat, and vmstat. OSWbba requires that you have installed Java version 1.4.2 or higher on your system.
You can use yum to install Java, or you can download a Java RPM for Linux from http://www.java.com. OSWbb is particularly useful for Oracle RAC (Real Application Clusters) and Oracle Grid Infrastructure configurations. The RAC-DDT (Diagnostic Data Tool) script file includes OSWbb, but does not install it by default
