perfSONAR v4.0 RC3 is out.   Hoping this is basically the final version for v4.0   If no problems are found a release could happen in a couple weeks.   Will need to get our sites update (auto-updates should run but needs checking)

Working on new mesh-configuration.   See https://meshconfig-itb.grid.iu.edu/     Will become the production version http://meshconfig.grid.iu.edu soon (next ~week).    Everyone can get an account if interested.  Need to request admin access for specific meshes if needed.

Lots of reorganization of network service components planned in OSG.  Will remove some ITB instances and rebalance resources (memory/CPU). New monitoring will be Docker based ETF running on CentOS7.3 VM.   https://gitlab.cern.ch/etf/docker/blob/master/README.md   Need updates for all services once perfSONAR v4.0 is released

Next week is the LHCONE/LHCOPN meeting at BNL.  Hope some of you will be attending.  https://indico.cern.ch/event/581520/

Analytics on network metrics showing occasional problems in packet loss at various locations.  Need to start opening tickets (after perfSONAR v4).

Analytics links:  

 http://tiny.cc/PktLossNoUnknown  (Shows 6 months of packet loss by src/dest)

 http://tiny.cc/pSLink   (Shows network stats by specific site)

Test emails by subscription are being issued, e.g.:

Dear Shawn McKee,

        this mail is to let you that there was a significant change in packet loss detected by PerfSONAR.

The site CA-SCINET-T2 (142.150.19.61)'s links got improved, total number from 5 to 0 links.
These are all the bad links for the past hour:


Best regards,
ATLAS AAS
