We start using pmm about 3 months ago and now we are facing some errors in dashboards. We are using pmm2 on docker. And we cannot open query analytics there is a error message on that dashboard saying “Error loading: pmm-qan-app-panel”. We also facing some error messages on Home page like Error loading: pmm-check-panel-home and Error loading: pmm-update. I updates Grafana with below commands:
yum update percona-dashboards
rm -rf /var/lib/grafana/plugins/pmm-app/
cp -r /usr/share/percona-dashboards/pmm-app/ /var/lib/grafana/plugins/
supervisorctl restart grafana
grafana-cli plugins ls | grep pmm-app
installed plugins:
pmm-app @ 2.21.0
Thank you for all your help.
