Working on issues with the OSG/WLCG MaDDash instance:  https://psmad.opensciencegrid.org/maddash-webui/

• Have issues with IPv6 (dual-stack) nodes because of underlying library that MaDDash depends upon.  perfSONAR developers are aware of the issue
• Currently there are cases where we have "grey" boxes that indicate no data BUT there actually is data.  Most are due to IPv6 issue but in some cases there may be firewall issues

The PWA (pSConfig GUI) at https://psconfig.opensciencegrid.org has some issues getting all the hosts published in OIM and GOCDB.   We are working on tracking down the problem in the code in GitHub:  https://github.com/soichih/gocdb2sls

We have seen some cases where perfSONAR toolkit deployments have default limits set that prevent testing from working.  The toolkits seem to be OK but test results are not showing up.  In some cases this is because of a 10GByte directory size limit.   The file to check for latency nodes is /etc/owamp-server/owamp-server.limits.   The value to increase is 'disk=10G'    Increase it to at least 50G (assuming your disk can hold this much).
