Ganglia is a scalable distributed system monitor tool for high-performance computing systems such as clusters and grids. It allows the user to remotely view live or historical statistics (such as CPUload averages or network utilization) for all machines that are being monitored.[1]

Ganglia[edit]
It is based on a hierarchical design targeted at federations of clusters. It relies on a multicast-based listen/announce protocol to monitor state within clusters and uses a tree of point-to-point connections amongst representative cluster nodes to federate clusters and aggregate their state. It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization. It uses carefully engineered data structures and algorithms to achieve very low per-node overheads and high concurrency. The implementation is robust, has been ported to an extensive set of operating systems and processor architectures, and is currently in use on over 500 clusters around the world. It has been used to link clusters across university campuses and around the world and can scale to handle clusters with 2000 nodes.[2]
The ganglia system comprises two unique daemons, a PHP-based web front-end, and a few other small utility programs.
Ganglia Monitoring Daemon (gmond)[edit]
Gmond is a multi-threaded daemon which runs on each cluster node you want to monitor. Installation does not require having a common NFS filesystem or a database back-end, installing
