Greetings group!
We recently reloaded a cluster from scratch using cephadm and reef. The cluster came up, no issues. We then decided to upgrade two existing cephadm clusters that were on quincy. Those two clusters came up just fine but there is an issue with the Grafana graphs on both clusters ( which were working before the upgrade ). They are now blank. There is an error in the Prometheus alerts (PrometheusJobMissing) that is alerting and it states the following:
The prometheus job that scrapes from Ceph is no longer defined, this will effectively mean you'll have no metrics or alerts for the cluster. Please review the job definitions in the prometheus.yml file of the prometheus instance.
summary: The scrape job for Ceph is missing from Prometheus
We deployed a fresh Ceph cluster with 18.2.0 and have the exact same error. So I'm not sure it's only broken for upgrades from quincy. Gr. Stefan
