perfSONAR User Q&A and Other Discussion

[Johann Hugo <>]

Hi all

Our MaDDash recently stopped working, everything orange

https://perf-cm.sanren.ac.za/

Installed MadDash version

perfsonar-centralmanagement.noarch     4.4.4-1.el7
perfsonar-psconfig-maddash.noarch      4.4.4-1.el7

The only problem I could find was with the postgresql database. I deleted the database + created a clean DB, but still orange

systemctl stop postgresql-10.service
cd /var/lib/pgsql/10/
mv data data.old
/usr/pgsql-10/bin/postgresql-10-setup initdb
/usr/lib/esmond-database/configure-pgsql.sh 10
rm -rf data.old/
systemctl start postgresql-10.service
/usr/lib/perfsonar/scripts/system_environment/configure_esmond --force

MadDash log files looks fine

It's reading the confings from the PWA server

I can see the test-points submitting there results

Any ideas ?
