The record

Purpose: Ganglia is a scalable distributed monitoring system for high-performance computing clusters and Grids.
Architecture: It uses a hierarchical design to monitor clusters and aggregate their state across federations of clusters.
Node monitoring: The multithreaded gmond daemon runs on each cluster node and monitors host state.
Cluster aggregation: The gmetad daemon polls data sources, stores numeric volatile metrics in round-robin databases, and exports aggregated XML to clients.
Web frontend: The PHP web frontend displays live monitoring data and historical graphs for metrics such as CPU, memory, disk, and network usage.
Custom metrics: The gmetric command-line tool can announce arbitrary host metrics.
Metric extensions: Gmond supports pluggable metric modules written in C or Python.
Transport and storage: Ganglia uses XML for data representation, XDR for transport, and RRDtool for data storage and visualization.
Supported platforms: The documentation lists Linux, FreeBSD, NetBSD, OpenBSD, DragonflyBSD, MacOS X, Solaris, AIX, IRIX, Tru64, HPUX, and Windows NT/XP/2000/2003/2008.
Deployment requirements: The web frontend depends on gmetad, and its documentation recommends a fairly powerful dedicated machine when displaying a large amount of data.
Additional dependency: Gmetad relies on RRDtool and is not compiled unless explicitly requested with the --with-gmetad flag.
Security: The project site warned that a Ganglia Web security issue could allow arbitrary script execution with web user privileges and advised upgrading or password-protecting publicly accessible installations.
License: The monitor-core repository lists the BSD-3-Clause license.
Components: The system includes the gmond monitoring daemon, gmetad aggregation daemon, and a PHP-based web frontend.
