The Department of Energy Sciences Network (ESnet), Indiana University, Internet2 and GÉANT  today announced the release of a new version of the open-source tool perfSONAR, which stands for Performance Service Oriented Network Monitoring Architecture.

perfSONAR is a jointly developed and widely deployed test and measurement infrastructure that is used by science networks and facilities around the world to measure and ensure network performance. As research and education institutions are increasingly reliant on networking, open-source tools like perfSONAR allow network engineers to test and measure network performance, with the ability to archive data in order to pinpoint and solve service problems that may span multiple networks and international boundaries

“As research is becoming increasingly data-intensive, the ability to pinpoint and eliminate network bottlenecks is critical in order to make the most effective use of networks,” said Inder Monga, ESnet director. “This new release leverages an open-source, time-series graphing package developed by ESnet that allows for easy exploration of measurement data.”

The updates in version 4.0 include:

  • new scheduling software called pScheduler that supports community-developed test tools
  • results archiving and analysis
  • new interactive time-series graphs for improved human analysis
  • support for email alerting in MaDDash
