Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and grids. It is based on a hierarchical design targeted at federations of clusters. Ganglia is currently in use on over 500 clusters around the world and has scaled to handle clusters with 2000 nodes.
Lilith is a logging and access event viewer for the Logback logging framework. It has features comparable to Chainsaw, a logging event viewer for log4j. This means that it can receive logging events from remote applications using Logback as their logging backend. It uses files to buffer the received events locally, so it is possible to keep vast amounts of logging events at your fingertip while still being able to check only the ones you are really interested in by using filtering conditions.
MultiTail lets you view one or multiple files like the original tail program. The difference is that it creates multiple windows on your console (with ncurses). Merging of 2 or more log files is possible. It can also use colors while displaying the log files (through regular expressions) for faster recognition of what is important. It can also filter lines (again with regular expressions). It has interactive menus for editing given regular expressions and deleting and adding windows. One can also have windows with the output of shell scripts and other software. When viewing the output of external software, MultiTail can mimic the functionality of tools like 'watch'.
Prewikka is a graphical front-end analysis console for the Prelude hybrid IDS framework. Prelude is a hybrid intrusion detection framework implementing an open communication layer for use by any security application. It offers the ability to unify currently available security tools into one, powerful, and distributed application. Providing numerous features, Prewikka facilitate the work of users and analysts. It provides alert aggregation, sensors and hearbeat views, and has user management and configurable filters. It has access to external tools such as whois and traceroute.
ProM is an extensible framework that supports a wide variety of process mining techniques in the form of plug-ins. Plug-ins currently support the import of and the conversion between several process modelling languages, including Petri nets (PNML, TPN), EPCs/EPKs (Aris graph format, EPML), and YAWL. Mining, analysis, and log filtering plug-ins are also available.
RRDutil is a a tool to collect statistics (typically every 5 minutes) from multiple servers, store the values in RRD databases (using RRDtool), and plot out pretty graphs to a Web server on demand. The graph types shown include CPU, memory, disk (space and I/O), Apache, MySQL queries and query types, email, Web hits, and more.
SiLK (System for Internet-Level Knowledge) consists of two sets of tools: a packing system and an analysis suite. The packing system receives Netflow V5 PDUs or IPFIX and converts them into a more space efficient format, recording the packed records into service-specific binary flat files. The analysis suite consists of tools that can read these flat files and then perform various query operations, ranging from per-record filtering to statistical analysis of groups of records. The analysis tools interoperate using pipes, allowing a user to develop a relatively sophisticated query from a simple beginning.
Tea4CUPS is similar in functionality to the *nix command "tee", but in the form of a CUPS (Common UNIX Printing System) backend. Tea4CUPS captures a print job's data in their final form while they are being sent to a printer (more precisely, to a CUPS backend), and at the same time allows you to dispatch these data to any number of commands.
