LPAR2RRD makes historical, future trends and nearly "realtime" CPU utilization graphs of LPARs and shared CPU usage of IBM Power servers. It collects complete physical and logical configuration of all servers/LPARs. It is agent-less (it gets everything from the HMC/SDMC or IVM). It supports all kinds of logical partitions (AIX/AS400/Linux/VIOS).
WOTS is a logfile monitoring utility written in Perl. It's based on swatch but is brand new. It can be configured to watch multiple logfiles and to generate actions based on (perl regex) patterns matched in those files. Logfile rotations and variable logfile names are all possible. The actions can be printing the message, executing an external command, and others.
