OVIS Cluster Monitor Available Free

By DE Editors

The initial version of OVIS, a software tool developed by Sandia National Laboratories (Livermore, CA) that provides real-time monitoring of computational computer clusters, is now available for free download here. 

Sandia researchers say OVIS offers a statistical approach to the problem of computational platform monitoring and analysis. OVIS observes the overall statistical properties and environmental effects of a cluster, characterizing individual device behaviors and comparing them to a large number of statistically similar devices. Individual node values that appear to deviate from the norm (given the current applicable model, as established by real-time analysis) are flagged as aberrant. OVIS also allows the system builder to visualize the spatial distribution of a particular characteristic over the entire system.

The baseline capabilities of OVIS currently available for download are visualization and correlation tools that display information about state variables (such as temperature, CPU utilization, and fan speed) and their aggregate statistics, statistical tools that present the cluster as a comparative ensemble (rather than as individual nodes), and an XML-based cluster configuration information template.

Though not part of the current download distribution, OVIS also incorporates a Bayesian inference scheme to infer models for the normal behavior of a system and to determine bounds on the probability of values manifested in the system. This and other advanced features will be available in future releases.

Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin company, for the U.S. Department of Energy’s National Nuclear Security Administration.
