Hello, I have issue with multiple of our clusters. It doesn't seem to be versions specific and just happens on our clusters which have been running for a while and have been through some version upgrades. In current cephadm versions prometheus is configured via service discovery from MGR. Relevant prometheus config looks like this: - job_name: 'ceph-exporter' honor_labels: true http_sd_configs: - url: http://X.X.X.X:8765/sd/prometheus/sd-config?service=ceph-exporter Issue is that mgr doesn't return any hosts. Just an empty array []. Prometheus doesn't scrap ceph-exporter and some of our grafana graphs are empty. :/ Other URLs in this config file work fine and generate valid sd configs. Has anyone else experienced this? Does anyone know how to fix this? Best regards Adam Prycki
