Enable Prometheus export module

Prometheus online docu


ceph mgr module enable prometheus

Enable Pool metrics
Selected pools

ceph config set mgr mgr/prometheus/rbd_stats_pools "pool1,pool2,poolN"

All pools

ceph config set mgr mgr/prometheus/rbd_stats_pools "*"

Enable performance counters in Prometheus
With the introduction of ceph-exporter daemon, the Prometheus module will no longer export Ceph daemon perf counters as prometheus metrics by default.
However, one may re-enable exporting these metrics by setting the module option exclude_perf_counters to false:

ceph config set mgr mgr/prometheus/exclude_perf_counters false

Configure firewall
Enable access to Prometheus export module from XorMon NG.
By default module accepts HTTP requests on port 9283.

XorMon NG storage configuration

• Configure hostnames/IPs
  If you are using a load balancer translating hostname to an active manager node, then you can fill in only the load balanced hostname.
  Otherwise, fill in IP addresses/hostnames of all CEPH manager nodes which can host the Prometheus module.
  You cen get a list of manager nodes from "ceph -s" command.
  
  
• Add storage into configuration from the UI:
  XorMon NG UI ➡ Settings icon ➡ Device ➡ Storage ➡ New ➡ Vendor:device ➡ Ceph
  
• Run "Test" for configured storage device, it must show "OK"
  
  
• Wait about 1 hour, then reload the web browser, you should see it in XorMon NG UI
