What is red* and black*?
Can I add their time difference monitoring at https://monitoring.place11.ungleich.ch
Ah - the time difference should probably better monitored on
monitoring1.place{5,6}, not on monitoring.place11.
monitoring.place11 should be mainly configured as "monitoring us from
outside".

To enable, ntp collector run the following command on targets only if the file is not all commented out.
cat > /etc/default/prometheus-node-exporter << EOFARGS="--collector.ntp --collector.ntp.server ::1"EOF
service prometheus-node-exporter restart
I think that the prometheus query node_ntp_offset would be the one we needed. For more details, please look https://github.com/prometheus/node_exporter/blob/master/docs/TIME.md.
