Hello Everyone, I have installed both Prometheus and Grafana on one of my manager nodes (Ubuntu 18.04), and have configured both according to the documentation. I have visible Grafana dashboards when visiting http://mon1:3000, but no data exists on the dashboard. Python errors are shown for the job_name: ceph in Prometheus. Below is my prometheus.yaml configuration global: scrape_interval: 5s scrape_configs: - job_name: prometheus static_configs: - targets: ['localhost:9090'] - job_name: 'ceph-exporter' static_configs: - targets: ['localhost:9100'] labels: alias: ceph-exporter - job_name: 'ceph' static_configs: - targets: ['localhost:9283'] labels: alias: ceph And, these are the Python errors shown when I view the details of the targets in Prometheus (http://mon1:9090/targets) Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/cherrypy/_cprequest.py", line 670, in respond response.body = self.handler() File "/usr/lib/python2.7/dist-packages/cherrypy/lib/encoding.py", line 220, in __call__ self.body = self.oldhandler(*args, **kwargs) File "/usr/lib/python2.7/dist-packages/cherrypy/_cpdispatch.py", line 60, in __call__ return self.callable(*self.args, **self.kwargs) File "/usr/share/ceph/mgr/prometheus/module.py", line 1060, in metrics return self._metrics(instance) File "/usr/share/ceph/mgr/prometheus/module.py", line 1074, in _metrics instance.collect_cache = instance.collect() File "/usr/share/ceph/mgr/prometheus/module.py", line 975, in collect self.get_rbd_stats() File "/usr/share/ceph/mgr/prometheus/module.py", line 734, in get_rbd_stats 'rbd_stats_pools_refresh_interval', 300) TypeError: unsupported operand type(s) for +: 'int' and 'str' If anyone has experienced this issue, and might have a solution, I would appreciate any assistance. Thank you, Todd
