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.

Release Notes: A modular metric interface for C and Python (DSO support) and scriptable metric module support with Python. All pre-existing metrics (CPU, network, disk, memory, etc.) were converted to metric modules. New metric modules were introduced: multicpu, multidisk, and tcp_conn status. Modular front-end graph support was added. Metric groups that can be viewed or hidden as desired were implemented. Additional scaling capacity was provided for systems with memory greater than 4TB. Native metric support for Windows was improved (Built with CygWin).

Ganglia seems to be a promising tool to represent visually what is happening on my cluster.

Is there any way I could get an invitation to clusteradmin.blogspot? I am very interested in learning more about the 'Ganglia overview.'

A short Ganglia overview for sysadmins new to Linux clusters.
If somebody is interested I made a general overview of cluster monitoring topic with Ganglia as a main example (including adding your own metrics).


Quick read + links for first-timers.
