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).

Gargoyle is an interface for small, widely available routers such as the Linksys WRT54G series and the La Fonera. It provides functionality above and beyond what the default software provides including sophisticated dynamic DNS, quality of service, and bandwidth monitoring tools. The primary goal is to provide a polished interface for these advanced tools that is at least as easy to configure as any existing firmware. This project is based on top of OpenWrt, but unlike other Web interfaces for OpenWrt it places a strong focus an usability and is meant for average users, not just power users.
mylbhelper helps dumb load balancers do their job. It monitors a local MySQL instance by periodically issuing a query. Should the query fail, a custom script, which typically would firewall off the load balancer, is executed. Likewise, when it comes back up, another script is executed. This means you can use any load balancer capable of distributing TCP traffic rather than one natively capable of talking MySQL. mylbhelper can also act solely as a monitoring daemon.
