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, mpstat, netstat, iostat, and top.
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.
