Lookup Service Dashboards upgrade

Thu, 25 Jul 2024 00:00:00 +0000

The perfSONAR public dashboard (aka Lookup Service dashboard) has just been upgraded. Thanks to Grafana 10 a new browsing UI has been implemented with improved filtering capabilities. It still lists all the perfSONAR public instances and provides useful statistics about those deployments so that perfSONAR users can find the best suited target perfSONAR node to make measurements.

Go ahead and test for yourself at https://stats.perfsonar.net!

We welcome your feedback on the perfSONAR user list.

perfSONAR Office Hours

Thu, 25 Jan 2024 00:00:00 +0000

In the wake of TLPW Perf Club coming to a close, the perfSONAR team has decided to try out a similar open forum for current and prospective users to discuss perfSONAR-related topics. We’re calling it perfSONAR Office Hours and plan to host it once per quarter as part of the ESNet CI Lunch and Learn series. Topics could include, but are not limited to:

Deployment
Making measurements and interpreting the results
System tuning
Ideas for new features

Bug reports and security concerns should, as always, be reported directly to the development team at perfsonar-developer@internet2.edu.

The first meeting will take place Friday, February 16 at 2:00 p.m. ET and can be attended using the regular CI Lunch and Learn Zoom at https://esnet.zoom.us/j/804696793. See the full CI Lunch and Learn series calendar at https://www.es.net/science-engagement/ci-engineering-lunch-and-learn-series.

We’re looking forward to your questions and discussion.

Statement on Operating System Support, 2023 Edition

Fri, 14 Jul 2023 00:00:00 +0000

NB: This is not a re-post from two years ago.

Last week, Red Hat announced that it has ceased distributing the source code for Red Hat Enterprise Linux to the public and barred its licensees from doing the same. This closes the loophole it left open that made Alma Linux and Rocky Linux (and, originally, CentOS) possible, or at least easier, in the first place. The maintainers of Alma and Rocky have indicated that Red Hat’s actions make their ability to maintain them more-complicated but should only have a minor impact on their release processes.

For our part:

Support for CentOS 7 will continue until it reaches end of life next June.

Support for perfSONAR on Alma and Rocky in their EL8 and EL9 flavors remains unchanged. While that support is currently considered beta, we will remove that designation once those builds have seen wide-enough use outside the development team to be considered stable. We do not anticipate major problems with either. Red Hat Enterprise Linux and Oracle Linux will continue to be supported on an advisory-only basis. This means the team may pass along any information arising from informal experimentation or reports from the community. Supporting these distributions will not be a priority, although we will integrate patches from the community that make perfSONAR work there and don’t cause problems for the officially-supported distributions.

Support for any forks of RHEL will be considered if they turn into viable distributions and the perfSONAR community appears to be headed for a critical mass of adopting them.

Our support for Debian and its derivatives will remain unchanged. As part of an upcoming reorganization of our Docker containers, we may start basing them on a Debian-derived distribution to avoid instability caused by upheaval in the EL-derived world.

The perfSONAR team has an in-person developers’ meeting scheduled for late next month, and this will be a topic of discussion. While we understand that, like two years ago, most of you are still trying to find your way through this, early feedback on where you’re headed will help us make decisions about what to support and get that support in place in a timely manner.

As always, if you have questions or concerns, please drop us a line at perfsonar-developer@internet2.edu.

New Lookup Service Dashboards

Fri, 28 Apr 2023 00:00:00 +0000

The new perfSONAR public dashboard is a powerful tool, built on top of the Lookup Service, the global directory of all perfSONAR public instances, that provides statistics about the public perfSONAR deployments all around the world. It is divided in five sections where you can find general information, maps, and specific data regarding the perfSONAR hosts and services.

You can filter and search for Communities, hostname, perfSONAR utilisation statistics and characteristics of the various public deployments. We welcome your feedback on the perfSONAR user list.

Go ahead and start exploring at https://stats.perfsonar.net!

And read more about it on the APNIC blog.

Getting Ready for perfSONAR 5.0

Thu, 23 Mar 2023 00:00:00 +0000

The release of 5.0 is only a few weeks away bringing with it major changes including replacement of the current Esmond data archive with Opensearch (an Apache licensed derivative of Elasticsearch). This talk will cover what you need to do to prepare including how to test with the latest beta version, highlight potential breaking changes and the impact on historical data. We’ll also highlight what to expect post-5.0 in terms of additional features and OS support.

This talk should be of interest to anyone currently running a perfSONAR host or looking to start using it.

Please plan to join us in one of the 2 following sessions on Friday March 31st:

at 11:00 CEST (UTC+2) for a GÉANT hosted InfoShare, watch the recording.
at 14:00 EDT (UTC-4) for a ESnet hosted CI Engineering Lunch & Learn, watch the recording.

We will also reserve time for questions and will welcome your feedback.

We look forward to seeing you on March 31st.

We’re currently looking for short (3-5 minutes) lightning talks about any perfSONAR-related subject and would welcome participation from the user community. If you have a topic, please send a short proposal to perfsonar-training@internet2.edu.

Registration is complimentary for Internet2 members, MoU partners, and InCommon participants. There is a small fee for non-members that can be waived for any current or prospective perfSONAR user. If you would like to attend and are unable to register at no charge using your existing credentials, please contact us at perfsonar-training@internet2.edu to request a complimentary registration code.

The full agenda and links for registration may be found at https://internet2.edu/techextra21/techextra21-schedule/perfsonar-day-2021.

We look forward to seeing you on November 3!

Statement on Operating System Support

Thu, 05 Aug 2021 00:00:00 +0000

As many of you are aware, Red Hat announced last December that all support for CentOS 8 will cease on December 31, 2021. At the time of the announcement, the perfSONAR team was in the process of a long-overdue port to that distribution; that project was halted pending an assessment of the post-CentOS landscape. During our recent developer meeting, the team had some discussions and would like to share the decisions made about operating system support:

CentOS 7 will continue to be fully-supported until its originally-scheduled end of life on June 30, 2024.

Alma Linux 8 will become fully-supported and the team’s primary environment for development, build and distribution. Our RPM repositories and ISO images will be built using this distribution. The first Alma-based release will be perfSONAR 5.0.

Rocky Linux 8 has a small amount of catching up to do relative to Alma but is shaping up to be a solid alternate. As it should be bug-compatible with Red Hat Enterprise Linux, we will be revisiting it regularly and anticipate supporting running the Alma-built RPMs there.

Red Hat Enterprise Linux 8 and Oracle Linux 8 will be supported on an advisory-only basis. This means the team may pass along any information arising from informal experimentation or reports from the community. Supporting these distributions will not be a priority, although we will integrate patches from the community that make perfSONAR work there and don’t cause problems for those we do support.

CentOS Stream will not be supported, but we may use it internally as a way to make support for distributions derived from Red Hat Enterprise Linux 9 more timely.

CentOS 8 will not be supported in any fashion.

There are no changes in current or future support for Debian and Ubuntu. There is work underway to make both first-class citizens in our development environment rather than the ports they have been previously. This should make perfSONAR on those distributions a better product.

We will, as always, have documentation and programs available to help with the migration from CentOS 7 to the new systems.

If you have questions or concerns, please drop us a line at perfsonar-developer@internet2.edu.
